Title says it all. I have set of preprocessing steps that I apply to my epoched data every time, so to cut time, I have the preprocessed data stored in .fif files. However, when I want to calculate source estimates, I can’t because when I read the file and apply the inverse solution, my epochs object has type EpochsFIF, not Epochs. I have a workaround, so I’m fine. But I hope this can be implemented.
I’m really surprised, as loading epochs from disk and applying the inverse operator to them is something we’re doing in MNE-BIDS-Pipeline without any issues. Could you please share a minimal example of the code you’re using, and the error messages you receive?
