Warning during JBM expriments

When running P800-21, I notice this warning coming from the JBM related part:

tx.py:117: UserWarning: Last split after end of file for IVAS JBM condition
warn("Last split after end of file for IVAS JBM condition")

Note from @tamarapu : "The warning appears because the JBM condition must have the concatenation undone according to the timescaling from the tracefile.

The warning is saying that the end of the last concatenated item is after the end of the file. This could be OK, or maybe some parts of the last item are lost, so it needs a check of the output compared to the reference/respective non-JBM IVAS condition"
