FreeSurfer does read and use the qform, but only if the sform is not valid. When writing, it writes the qform as the same as the sform.

Hi

Is the information concerning the q-form header field in Nifti-1 still accurate (in relation to freesurfer):

please see: http://nifti.nimh.nih.gov/nifti-1/support/FreeSurferandNIfTI1/view?searchter...

I am planning to update my data conversion code and include the q-form header field in a meaningful way. It would be nice if I could get it to work properly with both fsl and freesurfer.

Kind regards,

Niels van Strien
