Error in ft_volumerealign (line 593) tmpcfg.template.elec.chanpos = shape.pnt; % ft_interactiverealign needs the field chanpos Shape is got from ft_read_headshape, which doesn't return a pnt-field. I was using fieldtrip-20160225. headshape = ft_read_headshape(fullpath, 'unit', 'mm') headshape = pos: [366x3 double] fid: [1x1 struct] label: {366x1 cell} coordsys: 'neuromag' unit: 'mm' I realized after some time that it works in 20151119, which does return a pnt-field headshape = ft_read_headshape(fullpath, 'unit', 'mm') pnt: [366x3 double] fid: [1x1 struct] label: {1x366 cell} coordsys: 'neuromag' unit: 'mm' I guess it's just the naming of the field (pos) that makes the difference.

(In reply to Robert Oostenveld from comment #1) I searched though the code and found some more "pnt"s that were not replaced by "pos". I made some changes and merged them in the master branch. See https://github.com/fieldtrip/fieldtrip/pull/110
