[FieldTrip] Fwd: FT doesn't close .fif files

[Laurence Hunt]

Thanks Alex - I guess it might also be useful to add to the mne code instead, as long as it doesn't cause any problems elsewhere for other users...? Thinking about it, I reckon it would work if you used the same solution you suggested previously on your website, but just added

data.pos = ftell(data.fid); %before running fclose in fiff_setup_read_raw

and

fseek(raw.fid,raw.pos); %after re-opening the file in fiff_read_raw_segment

(...followed by an fclose of raw.fid at the end of fiff_read_raw_segment, of course).

If you did this, it would save us making any changes in fieldtrip at all :)
