XDS wants "unwarped" Bruker frames. Unwarping can be done within Proteum2.
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] .

CCD detectors: XDS only reads "unwarped" Bruker "sfrm" format frames; unwarping can be done within the Bruker software called Proteum2. See also 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 sfrmtools at [1] that extracts parameters relevant for data processing with XDS from headers of .sfrm files. See [2] .
