Hello Dr. Petracca,
It seems the MPCO recorder result file does not support relative path that directs to upper level folders. For example, file path "../model/res/mpcoRes.h5" would lead to “/model/res/mpcoRes.h5.mpco” which is not intended (due to the split function on line 4596 in the MPCORecorder.cpp file). This is not big issue and just noted for your info.
Regards,
Junfei
