NAME
aarm_magic.py
DESCRIPTION
Converts AARM data to best-fit tensor (6 elements plus sigma)
Original program ARMcrunch written to accomodate ARM anisotropy data
collected from 6 axial directions (+X,+Y,+Z,-X,-Y,-Z) using the
off-axis remanence terms to construct the tensor. A better way to
do the anisotropy of ARMs is to use 9,12 or 15 measurements in
the Hext rotational scheme.
SYNTAX
aarm_magic.py [-h][command line options]
OPTIONS
-h prints help message and quits
-usr USER: identify user, default is ""
-f FILE: specify input file, default is aarm_measurements.txt
-crd [s,g,t] specify coordinate system, requires er_samples.txt file
-fsa FILE: specify er_samples.txt file, default is er_samples.txt
-Fa FILE: specify anisotropy output file, default is arm_anisotropy.txt
-Fr FILE: specify results output file, default is aarm_results.txt
INPUT
Input for the present program is a series of baseline, ARM pairs.
The baseline should be the AF demagnetized state (3 axis demag is
preferable) for the following ARM acquisition. The order of the
measurements is:
positions 1,2,3, 6,7,8, 11,12,13 (for 9 positions)
positions 1,2,3,4, 6,7,8,9, 11,12,13,14 (for 12 positions)
positions 1-15 (for 15 positions)

NAME
thellier_magic_redo.py
DESCRIPTION
Calculates paleointensity parameters for thellier-thellier type data using bounds
stored in the "redo" file
SYNTAX
thellier_magic_redo [command line options]
OPTIONS
-h prints help message
-usr USER: identify user, default is ""
-fcr CRIT, set criteria for grading
-f IN: specify input file, default is magic_measurements.txt
-fre REDO: specify redo file, default is "thellier_redo"
-F OUT: specify output file, default is thellier_specimens.txt
-leg: attaches "Recalculated from original measurements; supercedes published results. " to comment field
-CR PERC TYPE: apply a cooling rate correction.
PERC should be a percentage of original (say reduce to 90%)
TYPE should be one of the following:
EG (for educated guess); PS (based on pilots); TRM (based on comparison of two TRMs)
-Fcr CRout: specify pmag_specimen format file for cooling rate corrected data
-ANI: there are anisotropy data to correct thellier results
-fan ANIFILE: specify rmag_anisotropy format file, default is rmag_anisotropy.txt

NAME
HUJI_magic.py
DESCRIPTION
converts HUJI 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 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
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
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
-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
-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
# to do! -ac B : peak AF field (in mT) for ARM acquisition, default is none
-ncn NCON: specify naming convention: default is #1 below
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
separate experiments ( AF, thermal, thellier, trm aquisition) should be seperate files
(eg. af.txt, thermal.txt, etc.)
HUJI masurement file format (space delimited text):
Spec lab-running-numbe-code Date Hour Treatment-type(T/N/A) Treatment(XXX.XX) dec(geo) inc(geo) dec(tilt) inc(tilt)
---------
conventions:
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)
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: Inclination 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
thellier_magic.py
DESCRIPTION
plots Thellier-Thellier, allowing interactive setting of bounds
and customizing of selection criteria. Saves and reads interpretations
from a pmag_specimen formatted table, default: thellier_specimens.txt
SYNTAX
thellier_magic.py [command line options]
OPTIONS
-h prints help message and quits
-f MEAS, set magic_measurements input file
-fsp PRIOR, set pmag_specimen prior interpretations file
-fan ANIS, set rmag_anisotropy file for doing the anisotropy corrections
-fcr CRIT, set criteria file for grading.
-fmt [svg,png,jpg], format for images - default is svg
-sav, saves plots with out review (default format)
-spc SPEC, plots single specimen SPEC, saves plot with specified format
with optional -b bounds adn quits
-b BEG END: sets bounds for calculation
BEG: starting step for slope calculation
END: ending step for slope calculation
-z use only z component difference for pTRM calculation
DEFAULTS
MEAS: magic_measurements.txt
REDO: thellier_redo
CRIT: NONE
PRIOR: NONE
OUTPUT
figures:
ALL: numbers refer to temperature steps in command line window
1) Arai plot: closed circles are zero-field first/infield
open circles are infield first/zero-field
triangles are pTRM checks
squares are pTRM tail checks
VDS is vector difference sum
diamonds are bounds for interpretation
2) Zijderveld plot: closed (open) symbols are X-Y (X-Z) planes
X rotated to NRM direction
3) (De/Re)Magnetization diagram:
circles are NRM remaining
squares are pTRM gained
4) equal area projections:
green triangles are pTRM gained direction
red (purple) circles are lower(upper) hemisphere of ZI step directions
blue (cyan) squares are lower(upper) hemisphere IZ step directions
5) Optional: TRM acquisition
6) Optional: TDS normalization
command line window:
list is: temperature step numbers, temperatures (C), Dec, Inc, Int (units of magic_measuements)
list of possible commands: type letter followed by return to select option
saving of plots creates .svg format files with specimen_name, plot type as name

-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
INPUT

NAME
specimens_results_magic.py
DESCRIPTION
combines pmag_specimens.txt file with age, location, acceptance criteria and
outputs pmag_results table along with other MagIC tables necessary for uploading to the database
SYNTAX
specimens_results_magic.py [command line options]
OPTIONS
-h prints help message and quits
-usr USER: identify user, default is ""
-f: specimen input magic_measurements format file, default is "magic_measurements.txt"
-fsp: specimen input pmag_specimens format file, default is "pmag_specimens.txt"
-fsm: sample input er_samples format file, default is "er_samples.txt"
-fsi: specimen input er_sites format file, default is "er_sites.txt"
-fla: specify a file with paleolatitudes for calculating VADMs, default is not to calculate VADMS
format is: site_name paleolatitude (space delimited file)
-fa AGES: specify er_ages format file with age information
-crd [s,g,t,b]: specify coordinate system
(s, specimen, g geographic, t, tilt corrected, b, geographic and tilt corrected)
Default is to assume geographic
NB: only the tilt corrected data will appear on the results table, if both g and t are selected.
-cor [AC:CR:NL]: colon delimited list of required data adjustments for all specimens
included in intensity calculations (anisotropy, cooling rate, non-linear TRM)
unless specified, corrections will not be applied
-pri [TRM:ARM] colon delimited list of priorities for anisotropy correction (-cor must also be set to include AC). default is TRM, then ARM
-age MIN MAX UNITS: specify age boundaries and units
-exc: use exiting selection criteria (in pmag_criteria.txt file), default is default criteria
-C: no acceptance criteria
-aD: average directions per sample, default is NOT
-aI: average multiple specimen intensities per sample, default is by site
-aC: average all components together, default is NOT
-pol: calculate polarity averages
-sam: save sample level vgps and v[a]dms, default is by site
-xSi: skip the site level intensity calculation
-p: plot directions and look at intensities by site, default is NOT
-fmt: specify output for saved images, default is svg (only if -p set)
-lat: use present latitude for calculating VADMs, default is not to calculate VADMs
-xD: skip directions
-xI: skip intensities
OUPUT
writes pmag_samples, pmag_sites, pmag_results tables

DESCRIPTION
Converts AARM data to best-fit tensor (6 elements plus sigma)
Original program ARMcrunch written to accomodate ARM anisotropy data
collected from 6 axial directions (+X,+Y,+Z,-X,-Y,-Z) using the
off-axis remanence terms to construct the tensor. A better way to
do the anisotropy of ARMs is to use 9,12 or 15 measurements in
the Hext rotational scheme.

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
UMICH_magic.py
DESCRIPTION
converts UMICH .mag format files to magic_measurements format files
SYNTAX
UMICH_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
-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
-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.
Format of UMICH .mag files:
Spec Treat CSD Intensity Declination Inclination metadata string
Spec: specimen name
Treat: treatment step
XXX T in Centigrade
XXX AF in mT
Intensity assumed to be total moment in 10^3 Am^2 (emu)
Declination: Declination in specimen coordinate system
Inclination: Declination in specimen coordinate system
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...)
