#!/bin/bash
# purpose: generate XDS.INP
# revision 0.03 . Kay Diederichs 2/2010
# revision 0.04 . Kay Diederichs 4/2010 - include alternative ORGX, ORGY calculations for ADSC
# revision 0.05 . Kay Diederichs 5/2010 - grep for "Corrected" in addition to "marccd"; needed for BESSY
# revision 0.06 . KD 6/2010 - add UNTRUSTED_RECTANGLE and UNTRUSTED_ELLIPSE; use `whereis catmar` and so on
# revision 0.07 . KD 6/2010 - decide about ORGX/Y info in MAR header being pixels or mm; other fixes
# tested with some datasets from ALS, SSRL, SLS and ESRF; only MARCCD, ADSC/SMV, PILATUS detectors; for other detectors, values must be manually filled in.
#
# usage: e.g. generate_XDS.INP "frms/mydata_1_???.img"
# make sure to have the two quotation marks !
# the ? are wildcards for the frame numbers.
#
# requirement for external programs(s):
# - for MARCCD detectors the "catmar" binary (which can be downloaded from http://www.marresearch.com/download.html) must be in $PATH
# - alternatively, the [[mccd_xdsparams.pl]] script (see http://strucbio.biologie.uni-konstanz.de/xdswiki/index.php/Mccd_xdsparams.pl ) will be used, courtesy of Ana Gonzalez.
#
# limitations:
# - frame numbers are assumed to start with 1 and run consecutively
#
# known problems:
# - for ADSC detectors, there are at least three ways to obtain ORGX and ORGY values from the header (see below);
# - the same might be a problem for MAR headers, too (not sure about this)
#
# notes for debugging of the script:
# - add the -v option to the first line, to see where an error occurs
# - comment out the removal of tmp1 and tmp2 in the last line
#
