  • Command to run psana is:
  • psana -c ./tstamp-filter-and-event-writer.cfg
  • For this configuration file psana will skip 10 events and loop over the next 100 events from the /reg/d/psdm/<INSTRUMENT>/<experiment>/xtc/e158-r0021-s0*-c00.xtc files and run consecutively modules = ImgAlgos.TimeStampFilter PSXtcOutput.XtcOutputModule. Parameters of these modules are described in the bottom part of the configuration file. Module TimeStampFilter passes events from the specified time interval and prints some useful information. Module XtcOutputModule will write passed events in the file with auto-generated name ./test_out/e158-r0021.xtcf.
  • See also: Module ImgAlgos::TimeStampFilter and PSXtcOutput::PSXtcOutput

  • Examples for Package

    py_img_algos

    pyimgalgos

  • Package py_img_algos pyimgalgos contains python modules which work with both frameworks pyana and psana.
  • Configuration file for pyana and/or psana should have relevant sections with parameters for [pyana] and/or [psana]. Alean section is ignored in each framework at run time. This is the only difference between two frameworks in the configuration file. All module descriptions are the same for two frameworks, as shown in examples below.
  • See description of modules in Package py_img_algospyimgalgos.

  • Example of configuration file for CSPAD

  • File py-xcs72913-r0049-cspad.cfg:
