Hi Mishkin the warp is highly nonlinear, so there is no matrix to describe it. The mapping is given by the ?h.sphere.reg file. cheers Bruce On Thu, 11 Feb 2010, Mishkin Derakhshan wrote: > Hi, > I am looking for the transformation matrix that takes my input volume > (orig.mgh) and maps it in

the fsaverage subject is in Talairach space (actually, mni305 space), so using the /transforms/talairach.xfm file in your subjects/mri dir will be the proper transform to use for transform to fsaverage space. n. On Thu, 2010-02-11 at 17:42 -0500, Mishkin Derakhshan wrote: > Hi, > I am looking for
