Mosflm Progress Report Harry Powell MRC -LMB, Cambridge Cosener’s House Tuesday 18 th March 2008
detectors - 1 1. Pilatus images - • • mini. CBF (“normal mode”) - okay full. CBF - okay, but not written the same as the mini. CBF (Dectris to respond) non. CBF (Dectris “native” format, has no useful header information) • to do: obliquity correction spatial distortion
detectors - 2 2. Bruker detectors • can be used after conversion with frm 2 frm to do: • • • two-theta arm corrections for i. Mosflm 1 -byte per pixel format blind region correction for phi scans using non-zero kappa
detectors - 3 3. Mar flat panel detector (mar 555) • • 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. •
processing enhancements - 1 4. 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 5. Support programming for i. Mosflm, training Luke e. g. XML brought up to date, e. g. for Testgen 6. Interface between i. Mosflm & ccp 4 i not considered a high priority, but have discussed with Pete Briggs and Luke. Should be straightforward to launch an i. Mosflm task from ccp 4 i, 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 8. • • Diamond related activities visiting ~once a fortnight helping with general data processing queries training beamline staff in DP discussions about image formats Pilatus 6 M & 2 M Mar. CCD both native and CBF formats (Jun Aishima)
et cetera - 2 9. Releases and downloads (as of 13: 05, March 14 th) • • ipmosflm 7. 0. 2 - 1076 (released 28/01/2008) “ 7. 0. 3 - 316 (released 29/02/2008) • • i. Mosflm 0. 6. 0 - 361 (including Windows: 452) “ 0. 6. 1 - 138 ( “ “ 203) 10. Teaching, lectures. . . Lund, Hamburg, GSK, Study Weekend 11. Bug fixes, user support, etc. . .
so, what’s next? • Backstops: Extending to rectangular backstops & arms (+ more general shapes). XML for i. Mosflm • Pilatus: spatial distortion and obliquity corrections. • Bruker: 1 -byte per pixel images tidy generalized code for multi-circle goniostats • i. Mosflm & ccp 4 i (Assisting in) Allowing launch of i. Mosflm from ccp 4 i • Generating test data for autoindexing.
