Error on retrieving meds (file.py)

[Fourkan246]

After selecting a new project when I selected a file (sample_patient.h5) to load, the console showed an error. TypeError: 'NoneType' object is not subscriptable.

nb: I found 'medication' & 'low_rate' dataset under group 'clinical' using HDFView.

These errors can be ignored for now. They are related to a hardcoded proof-of-concept code segment for event visualization. However, the exceptions are caught, printed, and ignored during code execution. Thus, this error output can be ignored.

There is an open issue (#1) to generalize the event visualization, and when this is done, this error output will be removed.
