Hi Deniz, yes, it should be in the mris_make_surfaces of that version. You need to run it with -dura memprage_echo%d.mgz 4
where 4 is the # of echoes, and the names would be memprage_echo0.mgz, memprage_echo1.mgz, memprage_echo2.mgz, and memprage_echo3.mgz. These must all be "conformed" to be 256^3 and 1mm isotropic, but *not* scaled, otherwise the T2* info will be lost by the differential scaling. cheers bruce On Thu, 7 Oct 2010, Deniz Ozgen wrote: > Hello All: > > I read the paper by Kouwe et al.
