Xdsstat

XDSSTAT is a home-brewn program that prints various statistics in the form of tables and images, that are not available from XDS itself.

Features

Tables

statistics (R-factors, misfits, unique reflections, correlation ...) for each frame

Images

The following quantities mapped onto the detector surface:

• misfits.pck: outliers identified in CORRECT. Useful to identify ice rings.
• rf.pck: R-factor
• anom.pck: anomalous signal
• nobs.pck: observed reflections (not very interesting)
• rlps.pck: reciprocal lorentz factor (not very interesting)

These images are in the .pck format and may be visualized by VIEW.

Availability

For now please send email to Kay dot Diederichs at uni-konstanz dot de. The binary program will soon be put on my webpages.

The source code is in Fortran90 and requires a Fortran90-compiled CCP4 library, so few people are currently in a position to compile and link the program. I might opensource it someday, but preferably as part of the XDS distribution.
