[FieldTrip] error when converting from spm to ft

[Zita Eva Patai]

Hello FT-ers

In the past i had no problem when converting my data from SPM (where i do
preprocessing and averaging) to FT (where I do my cluster-stats and
plotting)

Currently, I am using the new way to convert (previous version seems
outdated 'nspm2ftrip') and I am hitting a wall: it says my data is not in
the right format, ie: not freq data. But i know that it is...any advice
would be much appreciated! Not to mention is warns me my data is not
epoched when it is indeed so...

Thank you!
