Frequently asked questions


XTC files are read through psana, thus there is a chance that the psana.cfg file may also need modification.  This file specifies the Cheetah module to load for processing, as well as which detectors are read into Cheetah.  The detector information in particular may need to be changed for different experiment configurations and different instruments.  Hopefully this file does not need to be modified, but now you know it’s there just in case.

Q: Has something changed recently?

Check the change notes.  Sometimes improvements break back-compatibility in the interests of moving forwards.
