Hi Simon,

did you use the HDF5 file from a monitor? In this case the charge isn't written to the file (yet). A feature request for adding more information to HDF5 files from monitors has already been submitted.

Dear Simon,

Yes, that should be possible with pyOPALTools if the H5-file contains the charge information which, from what I can see in the code, it should have.

Can you share a minimal example of how you created the H5 file with OPAL? What OPAL version do you use?

Best regards,

Jochem

Subject: [Opal] Python: Return particle charges from H5-file

 

Dear OPAL-Team,

Is it possible to return the particle charges from an H5-file using python?

Unfortunately, the parser dataset does not contain the information whereby

mon = load_dataset(".", fname="tmp.h5")
mon._H5Dataset__parser.getStepDatasets()
>> ['bunchNumber', 'id', 'px', 'py', 'pz', 'time', 'turn', 'x', 'y', 'z']

Whereby

mon.getData("q")

consistently does not work.

Best regards
Simon
