Are the morphing matrices computed using mne.compute_morph_matrix
invertable?
if I call
morph_mat = mne.compute_morph_matrix
<https://martinos.org/mne/stable/generated/mne.compute_morph_matrix.html#mne.compute_morph_matrix>(subject_from,
subject_to,
stc_from.vertices, vertices_to,
subjects_dir=subjects_dir)
Is there a way to invert morph_mat to map from 'subject_to' to 'subject_from'
or should i just call compute_morph_matrix again, something like...
morph_mat_inv = mne.compute_morph_matrix
<https://martinos.org/mne/stable/generated/mne.compute_morph_matrix.html#mne.compute_morph_matrix>(subject_to,
subject_from,
vertices_to, stc_from.vertices,
subjects_dir=subjects_dir)
switching the to/from subject and vertices.
Is this the best way to map back and forth between subjects?
Thanks!
Luke
p.s. The use case is to map a group of subjects to a template
(fsaverage). Do stats, make labels
etc., in the template space and then to map these labels back into each subject.
