I cannot seem to be able to get MNE to correctly parse the event codes that are stored in my EGI/MFF files. When I try to retrieve events with
mne.find_events(raw, stim_channel='STI 014'), the original event codes seem to be overwritten and replaced by a sequence of numbers (in my case, from 1 to 9, as I have 9 event codes). This makes it impossible to be sure which number correspond to which original event code/condition.
During recording, we made sure that the stimulus being presented and the corresponding event code were sent to NetStation and recorded in the recording files. Proof of that comes from the fact that, when importing the very same recording in the
.set format, EEGlab annotations do include event code, even description and word.
Is there something I am missing about the MFF import function and/or event acquisition function? Thanks!
