Hi all,

EEGLAB supports adding custom field names in the event structure, on top of the default ones (type, latency, duration, urevent, epoch) :
https://sccn.ucsd.edu/wiki/Chapter_03:_Event_Processing#Event_fields

For instance I use a behaviour field to store the subjects responses on each epoch.

It would be very useful if one could somehow access those custom fields in MNE (maybe the option already exists but I haven't found it).

Best wishes,
Nicolas
