[FieldTrip] fiff_read_tag error

[Wong-Barnum, Mona]

I have some old Neuromag MEG/EEG data files that I’m trying to read.  One file is giving me a runtime error (the others appears ok):

        Read a total of 3 projection items:
                PCA-v1 (1 x 102) idle
                PCA-v2 (1 x 102) idle
                PCA-v3 (1 x 102) idle

Cannot handle other than dense or sparse matrices yet

Error in fiff_read_raw_segment (line 152)
            tag = fiff_read_tag(fid,this.ent.pos);

Error in ft_read_data (line 1105)
      dat =
      fiff_read_raw_segment(hdr.orig.raw,begsample+hdr.orig.raw.first_samp-1,endsample+hdr.orig.raw.first_samp-1,chanindx);

Any suggestions on how to debug/fix/read this file?  All help is appreciated as I’m just starting with FieldTrip.  Thanks!
