Mosflm Progress Report

2
detectors - 1

• Pilatus images -
• miniCBF (normal mode) - okay
• fullCBF - okay, but not written the same as the
  miniCBF (Dectris to respond)
• nonCBF (Dectris native format, has no useful
  header information)
• to do
• obliquity correction
• spatial distortion

3
detectors - 2

• Bruker detectors
• can be used after conversion with frm2frm
• to do
• two-theta arm corrections for iMosflm
• 1-byte per pixel format
• blind region correction for phi scans using
  non-zero kappa

4
detectors - 3

• Mar flat panel detector (mar555)
• Can be read okay now
• some issues over poor data quality (mostly seems
  to be hardware related)
• not a high priority - possible that even the one
  installed in Lund will be returned.

5
processing enhancements - 1

• Automated backstop masking
• discussed with François
• implemented independent version based on Canny
  method for circular backstops
• to do
• write XML
• rectangular backstops
• backstop arm
• general shape

infrastructure

• Support programming for iMosflm, training Luke
• e.g. XML brought up to date, e.g. for Testgen
• Interface between iMosflm ccp4i
• not considered a high priority, but have
  discussed with Pete Briggs and Luke. Should be
  straightforward to launch an iMosflm task from
  ccp4i, the other way round would need
  considerable thought given to the design.
• Two releases in this period - Mosflm versions
  7.0.2 and 7.0.3 (bug fix).

et cetera - 1

• Diamond related activities
• visiting once a fortnight
• helping with general data processing queries
• training beamline staff in DP
• discussions about image formats -
• Pilatus 6M 2M
• MarCCD both native and CBF formats (Jun Aishima)

10
et cetera - 2

• Releases and downloads (as of 1305, March 14th)
• ipmosflm 7.0.2 - 1076 (released 28/01/2008)
• 7.0.3 - 316 (released
  29/02/2008)
• iMosflm 0.6.0 - 361 (including Windows 452)
• 0.6.1 - 138 (
  203)
• Teaching, lectures...
• Lund, Hamburg, GSK, Study Weekend
• Bug fixes, user support, etc etc...

so, whats next?

• Backstops
• Extending to rectangular backstops arms (
  more general shapes).
• XML for iMosflm
• Pilatus
• spatial distortion and obliquity corrections.
• Bruker
• 1-byte per pixel images
• tidy generalized code for multi-circle
  goniostats
• iMosflm ccp4i
• (Assisting in) Allowing launch of iMosflm from
  ccp4i
• Generating test data for autoindexing.
