<div dir="ltr">Hello,<div><br></div><div>I have some epoched data that I created in python (using mne.Epochs) and then saved as a .fif file using the save() method of mne.Epochs. After saving it, I did some other processing, and now I'd like to load them again. But I'm actually not sure how to load these objects? mne.fiff.read_evoked doesn't seem to do it (I get an error 'Could not find evoked data'; the full traceback is below).</div>
<div><br></div><div>Also, is it possible to filter an mne.Epochs object? I didn't filter my raw data because I wanted to do ICA on the epochs. But now, as far as I can tell there is not a built-in filter() method for Epochs like there is for Raw, and mne.filter.low_pass_filter() seems to be a low-level function so I'm not sure if I should be calling it directly or not. </div>
<div><br></div><div>(My epochs are much larger than the time window I'm actually interested in, so I think it should be ok to filter; but if that's still not recommended, then another solution I could try is to run ICA on the epochs, apply those ICA weights back onto the raw data, filter the raw data, and then epoch again.)</div>
