			function [trans_head2mri] = fiff_read_coord_trans(transfile)

			% usage: [trans_head2mri] = fiff_read_coord_trans(transfile)
			%
			% input:
			% transfile = name of transformation fif file (usually stored in
			% the subject's Freesurfer directory in /mri/T1-neuromag/sets).
			%
			% output:
			% trans_head2mri = transformation structure from head to MRI coordinate systems.
			%
			% Note: the inverse transformation, from MRI to head coordinate systems
			% can be obtained by just taking the inverse:
			% trans_mri2head.from=5; trans_mri2head.to=4;
			% trans_mri2head.trans=inv(trans_head2mri.trans);
