Generate XDS.INP

From XDSwiki
Jump to: navigation, search

This script generates XDS.INP based on a list of frame names supplied on the commandline. It currently works for MarCCD, ADSC, Pilatus, Eiger, some Rigaku and one Bruker detector(s); since this is just a bash script, extension to other detectors should be very easy.

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

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.

On Mac OS X, installation of the "Command Line Tools" (from http://developer.apple.com/downloads; requires Apple ID) is required. These are also part of the (larger, but also free) Xcode package. This package comes with a license that has to be accepted by the user when running a Command Line Tool for the first time.

See also the Installation article.

Obtaining 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/\&nbsp\;/\ /g -e s/\&gt\;/\>/g -e s/\&lt\;/\</g -e s/amp\;//g -e s/\&quot\;/\"/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. On a Mac (which does not seem to have wget), one could try

 curl -L -o - http://strucbio.biologie.uni-konstanz.de/xdswiki/index.php/generate_XDS.INP | \
   sed -e s/\&nbsp\;/\ /g -e s/\&gt\;/\>/g -e s/\&lt\;/\</g -e s/amp\;//g -e s/\&quot\;/\"/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

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 “” in XDS.INP. And the more you click “save” button, the more “” appear. This looks like e.g.
SPACE_GROUP_NUMBER=0  ! 0 if unknown
UNIT_CELL_CONSTANTS= 70 80 90 90 90 90 Â
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.

Calling generate_XDS.INP from a Python script

It is recommended to use the subprocess.Popen() module instead of os.system():

 subprocess.Popen(["generate_XDS.INP",imagepath],stdout=outputfile)

where imagepath is a string containing the path to an image and outputfile is either a chosen variable for an output file or subprocess.PIPE if you're not interested in the output of the script.

The module os.system() internally uses /bin/sh to execute the command and overrides #!/bin/bash at the beginning of the script. While this is not a problem on most operating systems, /bin/sh points to dash instead of bash on Ubuntu, which leads to a program crash with the error message

 sh: 1: Syntax error: Bad fd number

Dependencies

The script makes use of many GNU commands, like ls, grep, egrep, awk, cut, cat, echo, wc, bc, head, sed, tail, cp, od, python. Some of them (like od and python) are only used in case of specific detectors (MarCCD and RAXIS, respectively). The script will only work if all the required commands are available. They reside in either the coreutils RPM, or specific RPMs (gawk, sed, bc, grep, python ...). Please note that to get the strings command on some Linux distributions (e.g. FC23) you need to install the binutils RPM package. For Eiger data processing, the h5dump program must be installed. This is part of hdf5-tools (Ubuntu) or hdf5 (RHEL).

An easy way to check for missing programs is

which ls grep egrep awk cut cat echo wc bc head sed tail cp od python strings h5dump

A command that should go a long way in providing all these tools for RedHat-derived distros is (as root)

yum -y install coreutils binutils gawk sed bc grep python hdf5

and for Ubuntu this would be (untested!)

sudo apt-get install coreutils binutils gawk sed bc grep python hdf5-tools

Limitations

  • The script tries to interpret the header of the frames, so is currently limited to Dectris (Pilatus, Eiger), ADSC (Quantum), Rigaku (several types), MAR (CCD and image plate) detectors, and one Bruker detector. Other detectors need some values to be manually filled into XDS.INP - the relevant places are marked with XXX. These are detector properties (type, pixel size and number, min and max counts in a pixel), and experimental parameters like oscillation range, wavelength, distance, and direct beam position (or rather: point of detector that is closest to the crystal). For fine-tuning of detector parameters, see the detector-specific templates.
  • The authors have made a "best effort" to provide a XDS.INP that results in the correct sign of the anomalous signal. In the case of one detector type (internally called Rigaku SMV) this requires reversal of one detector axis, and a negative DETECTOR_DISTANCE, as is found in some of the detector-specific templates. For an unusual or unknown detector setup, the correct sign of the anomalous signal needs to be established and verified e.g. with a good dataset from a test crystal that has a anomalous signal. The authors do not take any responsibility for problems arising from incorrect sign of the anomalous signal, nor - obviously! - for any other mischief arising in or from data processing.
  • At some beamlines, the ROTATION_AXIS should be -1 0 0 ("backwards") instead of the usual 1 0 0 ("horizontal"), or even 0 1 0 ("vertical") like at one of the PETRA Hamburg BLs. We have only just started the article Beamline notes, and the frame headers do not have this information, so the default chosen by generate_XDS.INP may be wrong and need manual correction.
  • Sometimes, the x- and y- values of the primary beam position recorded in the header should be used for ORGY and ORGX (i.e reversed) instead of as ORGX and ORGY. For ADSC, this has been implemented in the script for a number of beamlines. A beamline that is also known to have reversed X and Y is BM14 (ESRF; Mar CCD, as of April 2014) but the script does not currently implement the reversal.
