The only distinction between CsPad DataV1 and DataV2 is the sparsification of particular sections as given in the configuration object. That is DataV2 may be sparser. The actual hardware is kicking out DataV1 but the DAQ event builder is making a DataV2 when it can. Sometimes the DAQ sends the original DataV1 instead of the DataV2. This can be due to limited resources, in particular competition with resources required for compressing cspad in the xtc files. If you do not find a DataV2 in the Event, look for a DataV2

How do I set psana verbosity from the config file?

Most all psana options can be set from both the config file as well as the command line. Unfortunately verbosity cannot be set from a config file. That is

psana -v -v ...

has no config file equivalent. This is because verbosity is a function of the Message service that psana is a client of, rather than server for. Unfortunately this makes it difficult to turn on debugging messages from within a python script that is run as

python myscript.py

However one can configure the message logging service through the MSGLOGCONFIG environment variable. In particular

MSGLOGCONFIG=trace python myscript.py

or

MSGLOGCONFIG=debug python myscript.py

turns on trace or debug level MsgLog messages. The above examples were tested with the bash shell. For full details on configuring the MsgLogger through the MSGLOGCONFIG environment variables, see https://pswww.slac.stanford.edu/swdoc/releases/ana-current/doxy-all/html/group__MsgLogger.html
