Bruker data

SFRM files

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 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, Tim Grüne provides the program sfrmtools at [1]. 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.
