Then when I use raw.plot(), it complains that "ValueError: Must supply either Raw or Epochs" (Line 1492 in utils.py in the function "_compute_scalings"). The error is raised because mne doesn't consider the raw object created from EGI as an instance of the BaseRaw class. "type(raw)" returns mne.io.egi.egi.RawEGI. <br></div><div><br></div><div>I only started to see this error after a recent update of the mne from 0.10 to 0.15.dev0, and raw.plot() worked fine for EGI files in my previous version of mne. <br></div><div><br></div><div>I wonder if anyone knows a solution to this problem.
