[FieldTrip] Importing BESA EEG data to Fieldtrip

[Alina Tariq]

Hello,

We have EEG data that we preprocessed and source analyzed in BESA that we are now looking to move into Fieldtrip. We're exporting the data using the simple binary matrix format where the EEG data has a .dat extension, the events list has a .evt extension, and the header has a .generic extension. We're able to read in the EEG data using the besa2fieldtrip function, but we're not able to import the events/header information and hence are unable to epoch the data.

We attempted to use the BESA option where you export a file already epoched, but the program stopped responding each time so we're forced to go with the unepoched solution for now. Any help or advice on how we can get the .evt events file and .generic header file to be read in by Fieldtrip would be appreciated.

Thank you!
