The attached file can by copied over the existing talairach.xfm (you might want to make a backup copy).

To clarify for others reading this, you would only do this when you want to run make_average_subject on a single subject so as to resample a subject's surface to ico (useful for quantifying areal expansion/contraction, and for making MEG/EEG forward models with ico=4).

Message body

Hi all,

How do I replace talairach.xfm by an identity matrix to prevent reorienting of images when I make-average ?

Cheers

Lena
