I noticed that the dataset 'original/meg/bti248grad/e,rfhp1.0Hz,COH' resulted in ft_senstype=bti248, whereas I had expected bti248grad. Checking ft_chantype, I noticed that it is not aware of bti248grad or bti248grad_planar.

mbp> svn commit forward/ft_senstype.m test/test_bug1807.m Sending forward/ft_senstype.m Adding test/test_bug1807.m Transmitting file data .. Committed revision 6845. I have added bti248grad to ft_senstype where appropriate, but it won't be autodetected correctly since the channels are the same as for the bti248 system. To fix it, the appropriate grad.type should be added to the bti2grad function.

ft_chantype should deal with the bti248grad and bti248 system separately. At this moment all MEG channels are simply type 'meg', I suggest to make that meggrad and megmag respectively (consistent with neuromag and ctf).
