Generate XDS.INP: Difference between revisions

Revision as of 12:15, 22 July 2021

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 provide an absolute filename for the data files - one that starts with a slash ("/").

!/bin/bash
purpose: generate XDS.INP
tested with some datasets from ALS, SSRL, SLS, ESRF, BESSY, SPring-8 and PF; only MAR, ADSC/SMV, PILATUS, Eiger, RAXIS (in-house), Bruker (PHOTON II) detectors;
for other detectors, values marked with XXX must be manually filled in.

usage: e.g. generate_XDS.INP "/file/system/frms/mydata_1_???.img"
make sure to have the two quotation marks !
the ? are wildcards for the frame numbers.
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, the Xcode command line tools (from https://developer.apple.com/download/more/) are needed.
notes for debugging of the script:
- add the -x option to the first line, to see where an error occurs
- comment out the removal of tmp1 and tmp2 in the last line

fi 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! rm -f tmp1 tmp2

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.

See also Generate_XDS.INP#Dependencies below, and the Installation article.

Copying generate_XDS.INP from XDSwiki webserver

On Linux:

wget https://strucbio.biologie.uni-konstanz.de/pub/linux_bin/generate_XDS.INP
chmod a+x generate_XDS.INP

On Mac:

curl -o generate_XDS.INP https://strucbio.biologie.uni-konstanz.de/pub/linux_bin/generate_XDS.INP
chmod a+x generate_XDS.INP

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 “Ã” in XDS.INP. And the more you click “save” button, the more “Ã” 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.

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). The .h5 files collected at Diamond Light Source require a very new version of h5dump (namely h5dump 1.10) to extract the OVERLOAD parameter from the .h5 file; this version is available by default in Ubuntu 20.04 and RHEL/CentOS 8.

On Mac OS X, installation of the "Command Line Tools" (from http://developer.apple.com/downloads; requires Apple ID) is required (open a terminal and type xcode-select --install). 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 (e.g. strings) for the first time.

One way to check for missing programs is

#!/bin/bash
for i in  ls grep egrep awk cut cat echo wc bc head sed tail cp od python strings h5dump ; do 
    if [ ! -x /bin/$i ] && [ ! -x /usr/bin/$i ]; then 
      echo $i not found
    fi
done

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 ROTATION_AXIS, OSCILLATION_RANGE, X-RAY_WAVELENGTH, DETECTOR_DISTANCE, and XORG, YORG. 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 an 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. The frame headers do not have this information, so the default chosen by generate_XDS.INP may be wrong and need manual correction. Pls also see the article Beamline notes.
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.
there are apparently several flavours of HDF5 files produced at Diamond Light Source. They differ e.g. in the naming of the header items. This means that items like NX, NY, DETECTOR_DISTANCE and number of images cannot be found by the generate_XDS.INP script. Example: The data at /dls/i04-1/data/2021/mx28114-9/processing/Lenye_Diamini/ThiL/ThiL found during the CCP4 2021 online Cape Town workshop. A workaround is to use e.g. xia2 pipeline=3dii to process these files, and - if needed - extract those items from its output files, e.g. from DEFAULT/NATIVE/SWEEP1/index/XDS.INP .
