Hi SPM gurus,
I'm trying to set up forward models for the data I've collected so
far, and keep encountering this bug when I select 'EEG BEM' as the
head model after making meshes (I do subject-specific rather than
template meshes for most subjects) and co-registration:
=======
??? Attempted to access pvec(:,2); index out of bounds because
size(pvec)=[0,5].
Error in ==> fitsphere at 64
C = -0.5*pvec(2:4) / pvec(1);
Error in ==> triangle4pt at 62
[center,radius] = fitsphere(sph_pnt);
Error in ==> prepare_bemmodel at 167
vol = triangle4pt(vol);
Error in ==> ft_prepare_bemmodel at 11
[varargout{1:nargout}] = funhandle(varargin{:});
Error in ==> spm_eeg_inv_forward at 77
vol = ft_prepare_bemmodel(cfg, vol);
Error in ==> spm_eeg_inv_forward_ui at 46
D = spm_eeg_inv_forward(D);
=======
Has this been encountered before, and does anyone have suggestions for
what I might be doing wrong?
Cheers,
Laurence
p.s. If it's any use, I'm trying to run it on Matlab 2008a for Intel
mac, and collected simultaneous EEG/MEG using a Neuromag-306 setup.
I'm selecting a single shell for the MEG head model, but this works
fine when I do it with 3-shell sphere for EEG, so I imagine it's the
EEG head model which is causing the problems.
