Dear Davy,
There is some problem with the FIL FTP server and the archive file
downloaded from there is incomplete. I attach the headshape.mat file.
The purpose of loading this file is to improve coregistration of MEG
to sMRI by fitting the subject's headshape measured with 3D digitizer
to the scalp mesh derived from the structural scan. In the absence of
headshape coregistration can be done based on the 3 fiducials alone
and this should still give you good results if you can specify the
corresponding locations in the sMRI precisely enough.
Best,
Vladimir
