The CMCF supports a variety of data processing, data analysis, and model building programs. These programs can be run from a local terminal from any user workstation at the beamline or NX session. Some programs can also be run on our high-capacity data processing servers for fastest data processing.
The following sections detail the programs available to academic users, and how best to run each program.
|Program Name||Startup Command|
|HKL2000||not supported, users should contact firstname.lastname@example.org for up-to-date site files|
|Solve/Resolve||phenix or (various)|
|SHELX||ccp4i or (various)|
|ARP/wARP||ccp4i or (various)|
|mosgo (strategy determination)||msg|
|xdsgo (data processing)||xdsgo|
|sms (structure solution)||sms|
The CMCF has high-capacity data processing servers dedicated to serve users. Whenever possible, use a data processing console for fastest data processing using the following programs.
To access these servers, open a Data Processing console by clicking on the icon on the Desktop of the user workstation at the beamline or NX session.
XDS & Autoprocess
Using XDS is made easy at the CMCF through an in-house script called Autoprocess which generates the appropriate input files and runs XDS automatically. You can also use XDS in the traditional manner. We recommend running Autoprocess to generate the appropriate input files which you can then edit manually.
Off-site processing of .h5 files within XDS requires the Neggia library provided by Dectris. Key parameters can be extracted from the master.h5 file using any HDF5 viewer or via command line, although it is frequently much easier to just copy parameters from the xds.inp file generated by Autoprocess.

- HKL2000/3000 is not supported at this time
- Running HKL with data collected at CMCF will require a site file corresponding to the appropriate beamline. Users may contact the HKL support team directly for an up to date copy (email@example.com), or characterize their own site file using a known good high resolution lysozyme dataset.
- Historical site files can be found below. (click to download site file):
The following data analysis programs can either be run through a local terminal or in a Data Processing console (accessed by clicking on the icon on the desktop of the user workstation at the beamline or NX session). In some cases, speed will be improved by running in a data processing console, but some features of these programs are only accessible locally (for example, model building with Phenix).

Partha is a program developed by Peter Zwart [Acta Cryst. (2005) D61, 1437-1448] that simulates SAD data and estimates the likelihood of success of SAD phasing, given a set of parameters. "AutoPartha" is an application for using Partha, developed and adapted for use at the CMCF. It includes easily accessible choices of energies available at the facility, automatic calculations of theoretical f' and f" and an adaptive scoring mechanism based on the literature and experience.
The following model building programs are graphics applications that should be run from a local terminal on a user workstation at the beamline or NX session. Note: These applications are not available from the data processing servers.
MSG (Mosflm-Go) is a strategy determination program developed at CMCF. MSG uses Mosflm for cell indexing and strategy determination. To invoke MSG, type:
running msg with a specific frame name:
to enforce a specific space group:
msg frame_name -s 19 (or P212121)
to access recently collected frames in MxDC:
to change default oscillation angle for strategy determination:
msg frame_name -o 0.2
to access recently created frames via lsl:
lsl -m(works best in subdirectories)
All the above options could also be accessed with lsl. For example, to calculate a data collection strategy with the last created frames, specific space group, and oscillation angle type:
lsl -m -s 19 -o 0.5
Example of output:

XDSGO is a data reduction program, which was developed at CMCF. It utilises the XDS package for data reduction and Sadabs program for data correction and merging. To invoke XDSGO, navigate to your data folder and type:
To integrate multiple datasets the following command can be used:
xdsgo -m /path/to/first/data_directory /path/to/second/data_directory /path/to/N/data_directory
XDSGO creates input files for XDS, XSCALE, and SADABS and run those programs in sequence. Data conversion between XDS file format and SADABS file format is accomplished via the XDS2SAD program. XDSGO is designed to recover from all the posible errors and usualy does not require user input. It creates standard XDS output files and provides a data statistics report in html format. All the above mentioned files can be found in the "proc" direcotry created in the dataset directory from which it is run.
Example of data processing:
SMS is a structure solution program. It utilizes XPREP and SHELXT for data solution. It supports XDS, Scalepack, and shelx input file formats, and outputs the solution in a shelx compatible format. To invoke sms, navigate to your "proc" folder, created by XDSGO, and type:
sms -xds XDS_ASCII.HKL -f FORMULA -o OUTPUT_FILE_NAME
Both XDSGO and SMS can be run in sequence from your data directory using the following command:
sms -a -f FORMULA -o OUTPUT_FILENAME
Other SMS options can be accessed by typing:
which will result in the following output:
-h Print this help message
-o Output file name
-xds XDS input file
-sca Scalepack input file
-sx Shelx input file
-c Cell parameters (required by shelx file format)
-w Wavelength in Angstrom
-a Automatic data reduction (XDS), scaling (SADABS) and solution (SHELXT
