Dear Sheila, You can create a head model automatically via SPM batch prior to running the correction code as follows. Best, Vladimir --- %% Create a head model matlabbatch{1}.spm.meeg.source.headmodel.D = {fullfile(D)}; matlabbatch{1}.spm.meeg.source.headmodel.val = 1; matlabbatch{1}.spm.meeg.source.headmodel.comment = ''; matlabbatch{1}.spm.meeg.source.headmodel.meshing.meshes.template = 1; matlabbatch{1}.spm.meeg.source.headmodel.meshing.meshres = 3; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.fiducial(1).fidname = 'nas'; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.fiducial(1).specification.select = 'nas'; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.fiducial(2).fidname = 'lpa'; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.fiducial(2).specification.select = 'FIL_CTF_L'; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.fiducial(3).fidname = 'rpa'; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.fiducial(3).specification.select = 'FIL_CTF_R'; matlabbatch{1}.spm.meeg.source.headmodel.coregistration.coregspecify.useheadshape = 0; matlabbatch{1}.spm.meeg.source.headmodel.forward.eeg = 'EEG BEM'; matlabbatch{1}.spm.meeg.source.headmodel.forward.meg = 'Single Shell'; spm_jobman('run', matlabbatch); D = reload(D); On Thu, Nov 27, 2014 at 10:07 AM, Kerry, Sheila <[log in to unmask]> wrote: > Dear Valdimir, > > > > I work with Alex Leff and Zoe Woodhead.
