Dear Daniel,
I am exploring the Edit Tagset plugin. This sounds like exactly what I need because I do only want the coordinates of the 6 electrode tips in MNI space.
I made 6 tags in orig space and wrote out the tag locations to SS01_tags.tag
Then I used Vecwarp: Vecwarp -input SS01_anat+tlrc (this is the one transformed to MNI space using @auto_tlrc) -forward -input SS01_tags.tag -output SS01_tags_MNI.tag
Then I opened the Edit Tagset plugin again and selected the MNI anatomy (SS01_anat+tlrc). I used the "Read" button to try and read in the new SS01_tags_MNI.tag file. It did not ask me which .tag file (orig or MNI) I wanted to load. The tags that it automatically loaded were in the wrong locations.
Did I do something wrong at any of these steps?
Christine
