Mismatch in CAN_DataFrame.ID between API and asammdf

[YoBruce45]

Hi community,
i am observing the following mismatch between the python API and the asammdf-tool (which i use to make some validity checks)

• I parse my mdf searching for IDs, using simply:
  print ("groupCounter " + str(groupCounter) + " : "+ str(group.loc[group.index[0],"CAN_DataFrame.CAN_DataFrame.ID"]))

• in parallel I open the mdf with asammdf and display for the groups the "ID"column.

Output in python:

Output in asammdf:

So as we see, sometimes the IDs do not match with each other, please see group 4.
Did somebody already face this ? Is it possibly a setting issue?
Thanks in advance =)

The GUI tabular window has special handling for CAN IDs. Usually the ID is stored as uint32 in the measurement, and the most significant bit is used to mark if the message is extended or not. This bit is masked out before the ID is shown in the tabular window

mdf.get_group does not mask the MSB

Thank you very much for those precious hints ;)
