thanks for spotting this I made a typo with this commit: https://github.com/fieldtrip/fieldtrip/commit/c206109c4d0884c2bbfa3bfbb94ba20a3aaaf24f This fixes it: [master db82c6f] FIX - there was a typo in mne2grad, causing it to error (which was caught) and no grad or elec in ft_read_header. See http://bugzilla.fieldtriptoolbox.org/show_bug.cgi?id=3201 and thanks to Lau! 1 file changed, 1 insertion(+), 1 deletion(-)
