NAME
HUJI_magic.py
DESCRIPTION
converts Hebrew University, Jerusalem format files to magic_measurements format files
SYNTAX
HUJI_magic.py [command line options]
OPTIONS
-h: prints the help message and quits.
-usr USER: identify user, default is ""
-f FILE: specify HUJI format input file, required
-F FILE: specify output file, default is magic_measurements.txt
-LP [colon delimited list of protocols, include all that apply]
AF: af demag
T: thermal including thellier but not trm acquisition
N: NRM only
TRM: trm acquisition
ANI: anisotropy experiment
G: triple AF demag (GRM protocol)
-spc NUM : specify number of characters to designate a specimen, default = 0
-loc LOCNAME : specify location/study name, must have either LOCNAME
-dc B PHI THETA: dc lab field (in micro tesla) and phi,theta, default is none
NB: use PHI, THETA = -1 -1 to signal that it changes, i.e. in anisotropy experiment
-ac B : peak AF field (in mT) for ARM acquisition, default is none
-ncn NCON: specify naming convention: default is #1 below
-A: don't average replicate measurements
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
[8] this is a synthetic sample with no site name
NB: all others you will have to customize your self
or e-mail [email protected] for help.
INPUT
Best to put separate experiments (all AF, thermal, thellier, trm aquisition, Shaw, etc.) in
seperate files (eg. af.txt, thermal.txt, etc.)
Spec: specimen name
Treat: treatment step
XXX T in Centigrade
XXX AF in mT
for special experiments:
Thellier:
XXX.0 first zero field step
XXX.1 first in field step [XXX.0 and XXX.1 can be done in any order]
XXX.2 second in-field step at lower temperature (pTRM check)
XXX.3 second zero-field step after infield (pTRM check step)
XXX.3 MUST be done in this order [XXX.0, XXX.1 [optional XXX.2] XXX.3]
AARM:
X.00 baseline step (AF in zero bias field - high peak field)
X.1 ARM step (in field step) where
X is the step number in the 15 position scheme
(see Appendix to Lecture 13 - Lectures in Paleomagnetism, 2007)
TRM:
XXX.YYY XXX is temperature step of total TRM
YYY is dc field in microtesla
Intensity assumed to be total moment in 10^3 Am^2 (emu)
Declination: Declination in geographic coordinate system
Inclination: Declination in geographic coordinate system

OPTIONS
-f FILE: specify master txt file
-fpos FILE: specify stratigraphic position file (.saf format)
-F FILE: specify magic_measurements output file, default is: magic_measurements.txt
-Fsa FILE: specify output file, default is: er_samples.txt
-ncn NCON: specify naming convention: default is #2 below
-ocn OCON: specify orientation convention, default is #5 below
-mcd: specify sampling method codes as a colon delimited string: [default is: FS-FD:SO-POM]
FS-FD field sampling done with a drill
FS-H field sampling done with hand samples
FS-LOC-GPS field location done with GPS
FS-LOC-MAP field location done with map
SO-POM a Pomeroy orientation device was used
SO-ASC an ASC orientation device was used
SO-MAG orientation with magnetic compass
SO-SUN orientation with sun compass
-loc: location name, default="unknown"
-spc NUM : specify number of characters to designate a specimen, default = 0
-ins INST : specify instsrument name
-a: average replicate measurements
INPUT FORMAT
Input files are horrible 2G binary format (who knows why?)
Orientation convention:
[1] Lab arrow azimuth= mag_azimuth; Lab arrow dip=-field_dip
i.e., field_dip is degrees from vertical down - the hade [default]
[2] Lab arrow azimuth = mag_azimuth-90; Lab arrow dip = -field_dip
i.e., mag_azimuth is strike and field_dip is hade
[3] Lab arrow azimuth = mag_azimuth; Lab arrow dip = 90-field_dip
e.g. field_dip is degrees from horizontal of drill direction
[4] lab azimuth and dip are same as mag_azimuth, field_dip
[5] lab azimuth and dip are same as mag_azimuth, field_dip-90
[6] all others you will have to either customize your
self or e-mail [email protected] for help.
Magnetic declination convention:
Az will use supplied declination to correct azimuth
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
NB: all others you will have to customize your self
or e-mail [email protected] for help.

NAME
UU_magic.py
DESCRIPTION
takes Fort Hoofddijk (University of Utrecht) format magnetometer files and converts them to magic_measurements and er_samples.txt
SYNTAX
UU_magic.py [command line options]
OPTIONS
-f FILE: specify input file
-fpos FILE: specify stratigraphic position file (.saf format)
-F FILE: specify magic_measurements output file, default is: magic_measurements.txt
-Fsa FILE: specify output file, default is: er_samples.txt
-ncn NCON: specify naming convention: default is #1 below
-ocn OCON: specify orientation convention, default is #1 below
-mcd: specify sampling method codes as a colon delimited string: [default is: FS-FD:SO-POM]
FS-FD field sampling done with a drill
FS-H field sampling done with hand samples
FS-LOC-GPS field location done with GPS
FS-LOC-MAP field location done with map
SO-POM a Pomeroy orientation device was used
SO-ASC an ASC orientation device was used
SO-MAG orientation with magnetic compass
SO-SUN orientation with sun compass
-loc: location name, default="unknown"
-spc NUM : specify number of characters to designate a specimen, default = 0
-ins INST : specify instsrument name
INPUT FORMAT
Input files must be colon delimited:
"file_name", "instrument"
"specimen name","",az,pl,vol(cc),strike,dip
treatment,X,Y,Z,CSD,"yy-mm-dd","hh:mm"
Orientation convention:
[1] Lab arrow azimuth= mag_azimuth; Lab arrow dip=-dip
i.e., dip is degrees from vertical down - the hade [default]
[2] Lab arrow azimuth = mag_azimuth-90; Lab arrow dip = -dip
i.e., mag_azimuth is strike and dip is hade
[3] Lab arrow azimuth = mag_azimuth; Lab arrow dip = dip-90
e.g. dip is degrees from horizontal of drill direction
[4] Lab arrow azimuth = mag_azimuth; Lab arrow dip = dip
[5] Lab arrow azimuth = mag_azimuth; Lab arrow dip = 90-dip
[6] all others you will have to either customize your
self or e-mail [email protected] for help.
Magnetic declination convention:
Az is already corrected in file
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
NB: all others you will have to customize your self
or e-mail [email protected] for help.
OUTPUT
output saved in magic_measurements.txt & er_samples.txt formatted files
will overwrite any existing files

-Fsi FILE: specify output er_sites.txt file, default is er_sites.txt
-Fsa FILE: specify output er_samples.txt file, default is er_samples.txt # LORI
-n [gm,kg,cc,m3]: specify normalization
-A: don't average replicate measurements
-spc NUM : specify number of characters to designate a specimen, default = 0
-ncn NCON: specify naming convention
-loc LOCNAME : specify location/study name, must have either LOCNAME or SITEFILE or be a synthetic
-mcd [FS-FD:SO-MAG,.....] colon delimited list for method codes applied to all specimens in .sam file
-dc B PHI THETA: dc lab field (in micro tesla) and phi,theta, default is none
NB: use PHI, THETA = -1 -1 to signal that it changes, i.e. in anisotropy experiment
-ac B : peak AF field (in mT) for ARM acquisition, default is none
INPUT
Best to put separate experiments (all AF, thermal, thellier, trm aquisition, Shaw, etc.)
NOTES:
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length) [default]
[4-Z] XXXXYYY: YYY is sample designation with Z characters from site XXX
[5] all others you will have to either customize your
self or e-mail [email protected] for help.

NAME
2G_bin_magic.py
DESCRIPTION
takes the binary 2G format magnetometer files and converts them to magic_measurements, er_samples.txt and er_sites.txt file
SYNTAX
2G_bin_magic.py [command line options]
OPTIONS
-f FILE: specify input 2G (binary) file
-F FILE: specify magic_measurements output file, default is: magic_measurements.txt
-Fsa FILE: specify output file, default is: er_samples.txt
-Fsi FILE: specify output file, default is: er_sites.txt
-ncn NCON: specify naming convention: default is #2 below
-ocn OCON: specify orientation convention, default is #5 below
-mcd: specify sampling method codes as a colon delimited string: [default is: FS-FD:SO-POM]
FS-FD field sampling done with a drill
FS-H field sampling done with hand samples
FS-LOC-GPS field location done with GPS
FS-LOC-MAP field location done with map
SO-POM a Pomeroy orientation device was used
SO-ASC an ASC orientation device was used
SO-MAG orientation with magnetic compass
SO-SUN orientation with sun compass
-loc: location name, default="unknown"
-spc NUM : specify number of characters to designate a specimen, default = 0
-ins INST : specify instsrument name
-a: average replicate measurements
INPUT FORMAT
Input files are horrible mag binary format (who knows why?)
Orientation convention:
[1] Lab arrow azimuth= mag_azimuth; Lab arrow dip=-field_dip
i.e., field_dip is degrees from vertical down - the hade [default]
[2] Lab arrow azimuth = mag_azimuth-90; Lab arrow dip = -field_dip
i.e., mag_azimuth is strike and field_dip is hade
[3] Lab arrow azimuth = mag_azimuth; Lab arrow dip = 90-field_dip
i.e., lab arrow same as field arrow, but field_dip was a hade.
[4] lab azimuth and dip are same as mag_azimuth, field_dip
[5] lab azimuth is same as mag_azimuth,lab arrow dip=field_dip-90
[6] Lab arrow azimuth = mag_azimuth-90; Lab arrow dip = 90-field_dip
[7] all others you will have to either customize your
self or e-mail [email protected] for help.
Magnetic declination convention:
Az will use supplied declination to correct azimuth
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
NB: all others you will have to customize your self
or e-mail [email protected] for help.
OUTPUT
output saved in magic_measurements.txt & er_samples.txt formatted files
will overwrite any existing files

SYNTAX
JR6_txt_magic.py [command line options]
OPTIONS
-h: prints the help message and quits.
-f FILE: specify input file, or
-F FILE: specify output file, default is magic_measurements.txt
-Fsa: specify er_samples format file for appending, default is new er_samples.txt (Not working yet)
-spc NUM : specify number of characters to designate a specimen, default = 1
-loc LOCNAME : specify location/study name
-A: don't average replicate measurements
-ncn NCON: specify sample naming convention (6 and 7 not yet implemented)
-mcd [SO-MAG,SO-SUN,SO-SIGHT...] supply how these samples were oriented
-v NUM : specify the volume of the sample, default 2.5cm^3.
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX

NAME
sio_magic.py
DESCRIPTION
converts SIO .mag format files to magic_measurements format files
SYNTAX
sio_magic.py [command line options]
OPTIONS
-h: prints the help message and quits.
-usr USER: identify user, default is ""
-f FILE: specify .mag format input file, required
-fsa SAMPFILE : specify er_samples.txt file relating samples, site and locations names,default is none
-F FILE: specify output file, default is magic_measurements.txt
-Fsy: specify er_synthetics file, default is er_sythetics.txt
-Fsa: specify output er_samples file, default is NONE (only for LDGO formatted files)
-LP [colon delimited list of protocols, include all that apply]
AF: af demag
T: thermal including thellier but not trm acquisition
S: Shaw method
I: IRM (acquisition)
I3d: 3D IRM experiment
N: NRM only
TRM: trm acquisition
ANI: anisotropy experiment
D: double AF demag
G: triple AF demag (GRM protocol)
CR: cooling rate experiment.
The treatment coding of the measurement file should be: XXX.00,XXX.10, XXX.20 ...XX.70 etc. (XXX.00 is optional)
where XXX in the temperature and .10,.20... are running numbers of the cooling rates steps.
XXX.00 is optional zerofield baseline. XXX.70 is alteration check.
syntax in sio_magic is: -LP CR xxx,yyy,zzz,.....xx -A
where xx, yyy,zzz...xxx are cooling time in [K/minutes], seperated by comma, ordered at the same order as XXX.10,XXX.20 ...XX.70
if you use a zerofield step then no need to specify the cooling rate for the zerofield
It is important to add to the command line the -A option so the measurements will not be evraged.
But users need to make sure that there are no duplicate meaurements in the file
-V [1,2,3] units of IRM field in volts using ASC coil #1,2 or 3
-spc NUM : specify number of characters to designate a specimen, default = 0
-loc LOCNAME : specify location/study name, must have either LOCNAME or SAMPFILE or be a synthetic
-syn INST TYPE: sets these specimens as synthetics created at institution INST and of type TYPE
-ins INST : specify which demag instrument was used (e.g, SIO-Suzy or SIO-Odette),default is ""
-dc B PHI THETA: dc lab field (in micro tesla) and phi,theta, default is none
NB: use PHI, THETA = -1 -1 to signal that it changes, i.e. in anisotropy experiment
-ac B : peak AF field (in mT) for ARM acquisition, default is none
-ncn NCON: specify naming convention: default is #1 below
-A: don't average replicate measurements
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
NB: all others you will have to customize your self
or e-mail [email protected] for help.
[8] synthetic - has no site name
[9] ODP naming convention
INPUT
Best to put separate experiments (all AF, thermal, thellier, trm aquisition, Shaw, etc.) in
seperate .mag files (eg. af.mag, thermal.mag, etc.)
Format of SIO .mag files:
Spec Treat CSD Intensity Declination Inclination [optional metadata string]
Spec: specimen name
Treat: treatment step
XXX T in Centigrade
XXX AF in mT
for special experiments:
Thellier:
XXX.0 first zero field step
XXX.1 first in field step [XXX.0 and XXX.1 can be done in any order]
XXX.2 second in-field step at lower temperature (pTRM check)
XXX.3 second zero-field step after infield (pTRM check step)
XXX.3 MUST be done in this order [XXX.0, XXX.1 [optional XXX.2] XXX.3]
AARM:
X.00 baseline step (AF in zero bias field - high peak field)
X.1 ARM step (in field step) where
X is the step number in the 15 position scheme
(see Appendix to Lecture 13 - http://magician.ucsd.edu/Essentials_2)
ATRM:
X.00 optional baseline
X.1 ATRM step (+X)
X.2 ATRM step (+Y)
X.3 ATRM step (+Z)
X.4 ATRM step (-X)
X.5 ATRM step (-Y)
X.6 ATRM step (-Z)
X.7 optional alteration check (+X)
TRM:
XXX.YYY XXX is temperature step of total TRM
YYY is dc field in microtesla
Intensity assumed to be total moment in 10^3 Am^2 (emu)
Declination: Declination in specimen coordinate system
Inclination: Declination in specimen coordinate system
Optional metatdata string: mm/dd/yy;hh:mm;[dC,mT];xx.xx;UNITS;USER;INST;NMEAS
hh in 24 hours.
dC or mT units of treatment XXX (see Treat above) for thermal or AF respectively
xx.xxx DC field
UNITS of DC field (microT, mT)
INST: instrument code, number of axes, number of positions (e.g., G34 is 2G, three axes,
measured in four positions)
NMEAS: number of measurements in a single position (1,3,200...)

NAME
2G_bin_magic.py
DESCRIPTION
takes the binary 2G format magnetometer files and converts them to magic_measurements, er_samples.txt and er_sites.txt file
SYNTAX
2G_magic.py [command line options]
OPTIONS
-f FILE: specify input 2G (binary) file
-F FILE: specify magic_measurements output file, default is: magic_measurements.txt
-Fsa FILE: specify output file, default is: er_samples.txt
-Fsi FILE: specify output file, default is: er_sies.txt
-ncn NCON: specify naming convention: default is #2 below
-ocn OCON: specify orientation convention, default is #5 below
-mcd: specify sampling method codes as a colon delimited string: [default is: FS-FD:SO-POM]
FS-FD field sampling done with a drill
FS-H field sampling done with hand samples
FS-LOC-GPS field location done with GPS
FS-LOC-MAP field location done with map
SO-POM a Pomeroy orientation device was used
SO-ASC an ASC orientation device was used
SO-MAG orientation with magnetic compass
SO-SUN orientation with sun compass
-loc: location name, default="unknown"
-spc NUM : specify number of characters to designate a specimen, default = 0
-ins INST : specify instsrument name
-a: average replicate measurements
INPUT FORMAT
Input files are horrible mag binary format (who knows why?)
Orientation convention:
[1] Lab arrow azimuth= mag_azimuth; Lab arrow dip=-field_dip
i.e., field_dip is degrees from vertical down - the hade [default]
[2] Lab arrow azimuth = mag_azimuth-90; Lab arrow dip = -field_dip
i.e., mag_azimuth is strike and field_dip is hade
[3] Lab arrow azimuth = mag_azimuth; Lab arrow dip = 90-field_dip
i.e., lab arrow same as field arrow, but field_dip was a hade.
[4] lab azimuth and dip are same as mag_azimuth, field_dip
[5] lab azimuth is same as mag_azimuth,lab arrow dip=field_dip-90
[6] Lab arrow azimuth = mag_azimuth-90; Lab arrow dip = 90-field_dip
[7] all others you will have to either customize your
self or e-mail [email protected] for help.
Magnetic declination convention:
Az will use supplied declination to correct azimuth
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
NB: all others you will have to customize your self
or e-mail [email protected] for help.
OUTPUT
output saved in magic_measurements.txt & er_samples.txt formatted files

-spc NUM : specify number of characters to designate a specimen, default = 0
-loc LOCNAME : specify location/study name, must have either LOCNAME or SAMPFILE or be a synthetic
-syn INST TYPE: sets these specimens as synthetics created at institution INST and of type TYPE
-ins INST : specify which demag instrument was used (e.g, SIO-Suzy or SIO-Odette),default is ""
-dc B PHI THETA: dc lab field (in micro tesla) and phi,theta, default is none
NB: use PHI, THETA = -1 -1 to signal that it changes, i.e. in anisotropy experiment
-ac B : peak AF field (in mT) for ARM acquisition, default is none
-FT [SIO,LDGO] : file type. default is SIO (.mag file format)
-ncn NCON: specify naming convention: default is #1 below
-A: don't average replicate measurements
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXX[YYY]: YYY is sample designation with Z characters from site XXX
[5] site name same as sample
[6] site is entered under a separate column
[7-Z] [XXXX]YYY: XXXX is site designation with Z characters with sample name XXXXYYYY
NB: all others you will have to customize your self
or e-mail [email protected] for help.
[8] synthetic - has no site name

INPUT
Best to put separate experiments (all AF, thermal, thellier, trm aquisition, Shaw, etc.) in
seperate .mag files (eg. af.mag, thermal.mag, etc.)
Format of SIO .mag files:
Spec Treat CSD Intensity Declination Inclination [optional metadata string]
Spec: specimen name
Treat: treatment step
XXX T in Centigrade
XXX AF in mT
for special experiments:
Thellier:
XXX.0 first zero field step
XXX.1 first in field step [XXX.0 and XXX.1 can be done in any order]
XXX.2 second in-field step at lower temperature (pTRM check)
XXX.3 second zero-field step after infield (pTRM check step)
XXX.3 MUST be done in this order [XXX.0, XXX.1 [optional XXX.2] XXX.3]
AARM:
X.00 baseline step (AF in zero bias field - high peak field)
X.1 ARM step (in field step) where
X is the step number in the 15 position scheme
(see Appendix to Lecture 13 - Lectures in Paleomagnetism, 2007)
TRM:
XXX.YYY XXX is temperature step of total TRM
YYY is dc field in microtesla
Shaw:
XXX.YY XXX is AF field
YY=00 is AF of NRM
YY=01 is AF of ARM1
YY=02 is AF of TRM
YY=03 is AF of ARM2
specify temperature and field of Total TRM step on command line
Intensity assumed to be total moment in 10^3 Am^2 (emu)
Declination: Declination in specimen coordinate system
Inclination: Declination in specimen coordinate system
Optional metatdata string: mm/dd/yy;hh:mm;[dC,mT];xx.xx;UNITS;USER;INST;NMEAS
hh in 24 hours.
dC or mT units of treatment XXX (see Treat above) for thermal or AF respectively
xx.xxx DC field
UNITS of DC field (microT, mT)
INST: instrument code, number of axes, number of positions (e.g., G34 is 2G, three axes,
measured in four positions)
NMEAS: number of measurements in a single position (1,3,200...)
