Conversion command

  geometry_convert -h

  geometry_convert -d cspad -f geo-cspad-xpp.data -o geo-cspad-xpp-crystfel.geom              # conversion from psana to crystfel
  geometry_convert -d cspadv2 -f geo-cspad-xpp-crystfel.geom -o geo-cspad-xpp-back.data # conversion from crystfel to psana

Test of converter

CSPAD

Panel type SENS2X1:V1 describes cspad 2x1 panel geometry in psana. There are two types of cspad detectors, xpp- and cxi-like, w/o and with quads, which has different configuration both in psana and CrystFEL.

  cp /reg/g/psdm/detector/data_test/geometry/geo-cspad-test.data .
  geometry_convert -d cspad -f geo-cspad-test.data -o geo-cspad-test-cframe-psana.geom --cframe 0
  geometry_convert -d cspadv2 -f geo-cspad-test-cframe-psana.geom -o geo-cspad-test-back.data
  geometry_image -g geo-cspad-test.data -a /reg/g/psdm/detector/data_test/npy/nda-mfx11116-r0624-e005365-MfxEndstation-0-Cspad-0-max.txt -R10 -i0

Panel types

  cp /reg/g/psdm/detector/data_test/geometry/geo-epix10ka2m-test.txt .
  geometry_convert -d epix10ka -f geo-epix10ka2m-test.txt -o geo-epix10ka2m-test-cframe-psana.geom --cframe 0
  geometry_convert -d epix10ka -f geo-epix10ka2m-test-cframe-psana.geom -o geo-epix10ka2m-test-back.txt
  then see the minor difference between geo-epix10ka2m-test.txt and geo-epix10ka2m-test-back.txt
  or check image with each of geometry files:
  geometry_image -g geo-epix10ka2m-test-back.txt -a /reg/g/psdm/detector/data_test/npy/nda-mfxc00118-r0184-epix10ka2m-silver-behenate-max.txt -R10 -i0

jungfrau

There may be two segment descriptions Jungfrau:V1 and Jungfrau:V2 which represent the same panel from two sides. Forward test works for both, backward returns panels of the Jungfrau:V2 type.

  cp /reg/g/psdm/detector/data_test/geometry/geo-jungfrau-8-test.data .
  geometry_convert -d jungfrau -f geo-jungfrau-8-test.data -o geo-jungfrau-8-test-cframe-psana.geom --cframe 0
  geometry_convert -d jungfrau -f geo-jungfrau-8-test-cframe-psana.geom -o geo-jungfrau-8-test-back.data
  geometry_image -g geo-jungfrau-8-test.data -a /reg/g/psdm/detector/data_test/npy/nda-cxilv9518-r0008-jungfrau-lysozyme-max.npy -R10 -i0

pnccd

A waste majority of pnccd geometry files in psana use old-style segment description as PNCCD:V1 with matrix coordinate reference frame. Forward conversion from psana-to-CrystFEL naturally supports this format. However, this format is not convenient for uniform backward conversion from CrystFEL-to-psana the arbitrary Cartesian frame. Backward conversion use segment description as MTRX:V2 in output file. The same segment type can be used in the conversion from psana-to-CrystFEL, but all geometry constants for panel position and orientation needs to be changed.  This issue creates a mess in direct comparison between original   and forth-and-back converted geometry file. For now this type of test is unavailable.

Conversion from psana-to-CrystFEL was tested long time ago and presumably works.
