Hi!
Is there anyone out there who is using MNE with CTF data? I can read files, and save epochs and evokeds to files, but I cannot read them back without errors. I have not been able to find this problem in the Archives.
Details:
I can read my datasets using mne.io.read_raw_ctf(), all data are there, and all analyses using MNE-Python work just fine.
I can save epochs using epochs_save(epochs_fname). I get a file that seem to be of the correct size, no error messages. I use the suggested file name ending, ?-epo.fif?.
However, I cannot recover epochs using epochs = mne.read_epochs(epochs_fname). There is a long traceback, but if I cut out the middle part:
epochs = mne.read_epochs(epochs_fname)
