CCD detectors: XDS only reads "unwarped" Bruker "sfrm" format frames; unwarping can be done within the Bruker software called Proteum2. See also [[ccp4com:Bruker_data|Bruker data]].
     −
PHOTON detectors: XDS natively reads their .cbf files, and [[generate_XDS.INP]] generates XDS.INP for PHOTON II.

Tim Grüne provides a program <code>sfrmtools</code> at [https://homepage.univie.ac.at/tim.gruene/research/programs/conv/sfrmtools/] that extracts parameters relevant for data processing with XDS from headers of .sfrm files. See [https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=CCP4BB;ce43e97e.1907] .

Bruker instruments save frames in SFRM file format.

XDS correctly reads these files. Data from CCD detectors, however, need to be "unwarped"; unwarping can be done within the Bruker software called Proteum2. See also [[ccp4com:Bruker_software|Bruker software]]. Data from more recent detectors, in particular all Photon detectors, do not need to unwarped and can be processed directly with XDS.

For such files, [https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=CCP4BB;ce43e97e.1907 Tim Grüne] provides the program <code>sfrmtools</code> at [https://homepage.univie.ac.at/tim.gruene/research/programs/conv/sfrmtools/]. It extracts parameters relevant for data processing with XDS from the header. The output should be saved in a file - only three more keyword/parameter lines are required for a minimal XDS.INP, namely e.g.
 +
NAME_TEMPLATE_OF_DATA_FRAMES=/my/data/name_????.sfrm
 +
OVERLOAD=1000000
 +
INCIDENT_BEAM_DIRECTION=0 0 1
 +
Additional ones can of course be used to modify the operation of XDS, e.g.
 +
JOB= XYCORR INIT COLSPOT IDXREF DEFPIX INTEGRATE CORRECT
 +
INCLUDE_RESOLUTION_RANGE=50 1
 +
TRUSTED_REGION=0 1.4142
 +
! UNTRUSTED_QUADRILATERAL= <8 numbers, easily specified using XDSGUI>
 +
...
 +
 
 +
 
 +
== CBF files ==
 +
 
 +
New detector types (optionally?) write CBF files, which XDS natively reads. [[generate_XDS.INP]] generates XDS.INP for CBF data written by the PHOTON II detector.
