so to be clear about it, suppose T1 is the matrix in aseg and T2 is the one in rawavg, to transform from aseg to rawavg I will apply invert(T1)*T2 is that correct?

there are two transformation matrices one in aseg and one in rawavg, how do I use them ?

great, so if I can read the header from the aseg file and the header from the rawavg header file I would be able to transfer any point from the aseg space to the rawavg space is that correct ?

it registers them based on the header information, but since the aseg is derived from the rawavg that should be exactly correct

And it exactly does that, does it register them together or use a pre-known transformation matrix On 04/11/2012 3:46 PM, Bruce Fischl wrote: > Hi Johnson > > I believe it resamples the aseg to have the same geometry as the original > scan. > > cheers > Bruce > On Wed, 11 Apr 2012, Johnson wrote: > >> Hi >> Can someone tell me please in details what does this line do? >> mri_label2vol --seg aseg.mgz --temp rawavg.mgz --o aseg-in-rawavg.mgz >> --reg >> header aseg.mgz >> thanks >> >> > The information in this e-mail is intended only for the person to whom it > is > addressed.
