4D/BTi headshape file

This is a 4D/BTi headshape file of representative subject, which can be used in combination with HCP MEG data for software that requires a hs_file. The headshape of HCP subjects is not released due to privacy restrictions. The headshape of HCP subjects is also not required for coregistration, since the coregistration is already done and transformations between various coordinate systems are shared in the anatomy package of each HCP subject.
