Hello,

I?m trying to save epoch data using the epochs.save() method. Everything  
seems to work fine, but when I read the data using mne.read\_epochs() and  
try to extract a subset of the events, I get the following error ?

In [50]: epo['faces']

hi Alan,

can you open an issue on github, provide a minimal code snippet  
to reproduce the bug and given your previous contributions to MNE-Python  
maybe even dig into it to get the cause of the problem?

Best,  
Alex

Woops. I can't seem to reproduce the error today, so I must have been doing  
something wrong yesterday.

Thanks!
