files for use with PmagPy plotting software
SYNTAX
kly4s_magic.py -h [command line options]
OPTIONS
-h: prints the help message and quits
-i: allows interactive input of input/output filenames
-f FILE: specify .ams input file name
-fad AZDIP: specify AZDIP file with orientations, will create er_samples.txt file
-fsa SFILE: specify existing er_samples.txt file with orientation information
-fsp SPFILE: specify existing er_specimens.txt file for appending
-F MFILE: specify magic_measurements output file
-Fa AFILE: specify rmag_anisotropy output file
-ocn ORCON: specify orientation convention: default is #3 below -only with AZDIP file
-usr USER: specify who made the measurements
-loc LOC: specify location name for study
-ins INST: specify instrument used
-spc SPEC: specify number of characters to specify specimen from sample
-ncn NCON: specify naming convention: default is #1 below
DEFAULTS
MFILE: magic_measurements.txt
AFILE: rmag_anisotropy.txt
SPFILE: create new er_specimen.txt file
USER: ""
LOC: "unknown"
INST: "SIO-KLY4S"
SPEC: 1 specimen name is same as sample (if SPEC is 1, sample is all but last character)
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)
[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.
Orientation convention:
[1] Lab arrow azimuth= azimuth; Lab arrow dip=-dip
i.e., dip is degrees from vertical down - the hade [default]
[2] Lab arrow azimuth = azimuth-90; Lab arrow dip = -dip
i.e., azimuth is strike and dip is hade
[3] Lab arrow azimuth = azimuth; Lab arrow dip = dip-90
e.g. dip is degrees from horizontal of drill direction
[4] Lab arrow azimuth = azimuth; Lab arrow dip = dip
[5] Lab arrow azimuth = azimuth; Lab arrow dip = 90-dip
[6] all others you will have to either customize your
self or e-mail [email protected] for help.

NAME
UB_magic.py
DESCRIPTION
takes University of Barcelona format magnetometer files and converts them to magic_measurements and er_samples.txt
SYNTAX
UB_magic.py [command line options]
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.
OUTPUT
output saved in magic_measurements.txt & er_samples.txt formatted files
will overwrite any existing files

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

NAME
orientation_magic.py
DESCRIPTION
takes tab delimited field notebook information and converts to MagIC formatted tables
SYNTAX
orientation_magic.py [command line options]
OPTIONS
-f FILE: specify input file, default is: orient.txt
-Fsa FILE: specify output file, default is: er_samples.txt
-Fsi FILE: specify output site location file, default is: er_sites.txt
-app append/update these data in existing er_samples.txt, er_sites.txt files
-ocn OCON: specify orientation convention, default is #1 below
-dcn DCON [DEC]: specify declination convention, default is #1 below
if DCON = 2, you must supply the declination correction
-BCN don't correct bedding_dip_dir for magnetic declination -already corrected
-ncn NCON: specify naming convention: default is #1 below
-a: averages all bedding poles and uses average for all samples: default is NO
-gmt HRS: specify hours to subtract from local time to get GMT: default is 0
-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
INPUT FORMAT
Input files must be tab delimited and have in the first line:
tab location_name
Note: The "location_name" will facilitate searching in the MagIC database. Data from different
"locations" should be put in separate files. The definition of a "location" is rather loose.
Also this is the word 'tab' not a tab, which will be indicated by '\t'.
The second line has the names of the columns (tab delimited), e.g.:
site_name sample_name mag_azimuth field_dip date lat long sample_lithology sample_type sample_class shadow_angle hhmm stratigraphic_height bedding_dip_direction bedding_dip GPS_baseline image_name image_look image_photographer participants method_codes site_description sample_description GPS_Az, sample_igsn, sample_texture, sample_cooling_rate, cooling_rate_corr, cooling_rate_mcd
Notes:
1) column order doesn't matter but the NAMES do.
2) sample_name, sample_lithology, sample_type, sample_class, lat and long are required. all others are optional.
3) If subsequent data are the same (e.g., date, bedding orientation, participants, stratigraphic_height),
you can leave the field blank and the program will fill in the last recorded information. BUT if you really want a blank stratigraphic_height, enter a '-1'. These will not be inherited and must be specified for each entry: image_name, look, photographer or method_codes
4) hhmm must be in the format: hh:mm and the hh must be in 24 hour time.
date must be mm/dd/yy (years < 50 will be converted to 20yy and >50 will be assumed 19yy)
5) image_name, image_look and image_photographer are colon delimited lists of file name (e.g., IMG_001.jpg) image look direction and the name of the photographer respectively. If all images had same look and photographer, just enter info once. The images will be assigned to the site for which they were taken - not at the sample level.
6) participants: Names of who helped take the samples. These must be a colon delimited list.
7) method_codes: Special method codes on a sample level, e.g., SO-GT5 which means the orientation is has an uncertainty of >5 degrees
for example if it broke off before orienting....
8) GPS_Az is the place to put directly determined GPS Azimuths, using, e.g., points along the drill direction.
9) sample_cooling_rate is the cooling rate in K per Ma
10) int_corr_cooling_rate
11) cooling_rate_mcd: data adjustment method code for cooling rate correction; DA-CR-EG is educated guess; DA-CR-PS is percent estimated from pilot samples; DA-CR-TRM is comparison between 2 TRMs acquired with slow and rapid cooling rates.
is the percent cooling rate factor to apply to specimens from this sample, DA-CR-XX is the method code

Samples are oriented in the field with a "field arrow" and measured in the laboratory with a "lab arrow". The lab arrow is the positive X direction of the right handed coordinate system of the specimen measurements. The lab and field arrows may not be the same. In the MagIC database, we require the orientation (azimuth and plunge) of the X direction of the measurements (lab arrow). Here are some popular conventions that convert the field arrow azimuth (mag_azimuth in the orient.txt file) and dip (field_dip in orient.txt) to the azimuth and plunge of the laboratory arrow (sample_azimuth and sample_dip in er_samples.txt). The two angles, mag_azimuth and field_dip are explained below.
[1] Standard Pomeroy convention of azimuth and hade (degrees from vertical down)
of the drill direction (field arrow). lab arrow azimuth= sample_azimuth = mag_azimuth;
lab arrow dip = sample_dip =-field_dip. i.e. the lab arrow dip is minus the hade.
[2] Field arrow is the strike of the plane orthogonal to the drill direction,
Field dip is the hade of the drill direction. Lab arrow azimuth = mag_azimuth-90
Lab arrow dip = -field_dip
[3] Lab arrow is the same as the drill direction;
hade was measured in the field.
Lab arrow azimuth = mag_azimuth; Lab arrow dip = 90-field_dip
[4] lab azimuth and dip are same as mag_azimuth, field_dip : use this for unoriented samples too
[5] Same as AZDIP convention explained below -
azimuth and inclination of the drill direction are mag_azimuth and field_dip;
lab arrow is as in [1] above.
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:
[1] Use the IGRF value at the lat/long and date supplied [default]
[2] Will supply declination correction
[3] mag_az is already corrected in file
[4] Correct mag_az but not bedding_dip_dir
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 = sample name
[6] site name entered in site_name column in the orient.txt format input file
[7-Z] [XXX]YYY: XXX is site designation with Z characters from samples XXXYYY
NB: all others you will have to either customize your
self or e-mail [email protected] for help.

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.

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
