Generate XDS.INP
Jump to navigation
Jump to search
This script generates XDS.INP based on a list of frame names supplied on the commandline. It currently works for MarCCD, ADSC, Pilatus and a few Rigaku detectors; since this is just a bash script, extension to other detectors is very easy.
On Mac OS X, installation of the "Command Line Tools" (from http://developer.apple.com/downloads; requires Apple ID) is required (I think). These are a part of the (larger, but also free) Xcode package.
Usage
Usage is just (don't forget the quotation marks!):
generate_XDS.INP "/home/myname/frms/mydata_1_???.img"
XDS supports bzip2-ed frames. Thus, when specifying the frame name parameter of the script, you should leave out any .bz2 extension.
For improved interaction with XDSGUI, it is advantageous to use an absolute filename - one that starts with a slash ("/").
The script
#!/bin/bash
# purpose: generate XDS.INP
#
# tested with some datasets from ALS, SSRL, SLS, ESRF, BESSY, SPring-8 and PF; only MARCCD, ADSC/SMV, PILATUS, RAXIS (in-house) detectors;
# for other detectors, values marked with XXX 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.
#
# 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)
# - on Mac OS X, Xcode (from http://developer.apple.com/tools/xcode) might be needed - 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

echo XDS.INP is ready for use. The file has only the most important keywords.
echo Full documentation, including complete detector templates, is at
echo http://www.mpimf-heidelberg.mpg.de/~kabsch/xds . More documentation in XDSwiki
echo After running xds, inspect, using XDS-Viewer, at least the beamstop mask in
echo BKGPIX.cbf, and the agreement of predicted and observed spots in FRAME.cbf!

System-wide or personal installation
Ask your system adminstrator to cut-and-paste the script into e.g. /usr/local/bin/generate_XDS.INP, and to make it "executable".
But you may also cut-and-paste the script from this webpage into a file in e.g. your home directory; the filename should be generate_XDS.INP. After creating the file, make it executable - e.g. if it's in your $HOME, use:
chmod +x ~/generate_XDS.INP
After that, you can just run it in a similar way as if it were installed in your $PATH:
~/generate_XDS.INP "frms/mydata_1_???.img"
By using your own file, you can easily update to the latest revision, or even change the script, without having to bother the system administrator.
Generating generate_XDS.INP from this webpage
Instead of cutting-and-pasting the lines of the script, you (or the system administrator) could just cut-and-paste the following four lines
wget http://strucbio.biologie.uni-konstanz.de/xdswiki/index.php/generate_XDS.INP -O - | \ sed -e s/\ \;/\ /g -e s/\>\;/\>/g -e s/\<\;/\</g -e s/amp\;//g -e s/\"\;/\"/g -e s/\&\#\1\6\0\;/\ /g | \ sed '/# end of generate_XDS.INP/,$d' | awk '/^#/,/rm -f tmp1 tmp2/' > generate_XDS.INP chmod +x generate_XDS.INP
to copy the script from this website into an executable file generate_XDS.INP in your current directory.
If you do use cut-and-paste from the webpage, be aware of the following problem report: On the Mac, after loading frames, by clicking “generate XDS.INP”, the program gives some strange symbol “Ô in XDS.INP. And the more you click “save” button, the more “Ô appear. This looks like e.g.
SPACE_GROUP_NUMBER=0 Ã ! 0 if unknown
UNIT_CELL_CONSTANTS= 70 80 90 90 90 90 Ã
The problem is due to the “Rich text” format in TextEdit when saving "generate_XDS.INP". It is solved by re-downloading the script, and changing format to Plain - everything should work then.
