This has nothing to do with the input format: once the data is loaded into MNE, it’s essentially all the same, no matter if the data was originally stored as an EDF or FIFF or BrainVision file on disk. Once you’ve loaded your raw data, you can use Raw.rename_channels() to fix the channel naming. Th…

Hello, could you please share the full error message? (And to get good formatting, first paste it into the forum editor window, then select it, and click on the “Preformatted text” button in the toolbar; I’ve edited your previous post in a similar way to improve readability)

You need to pass on_missing=‘ignore’ to your call to set_montage() in line 3; or drop the channels that are not present in the montage from the data; or use a montage that actually contains all the channel names that are present in your data. All problematic channel names end with -Pz, what does t…

Each electrode was normalized through the subtraction of the Pz electrode!

This may be the case, but the electrodes don’t have standard naming anymore, so the montage that ships with MNE cannot be applied to them. So the easiest solution is probably to rename the electrodes to get rid of the suffix that was added through referencing. Let me know if you need help doing that…

This was very helpful! Thank you!

Thank you for that input. Realistically I will normally be working with edfs. Do you know the syntax for renaming edf channels?
