Hi Paul,

yes, take a look here:

should be similar to what you want to do (base and long are in the same space), you would not need the lta_convert command, I think as you are going to brainmask, not the rawavg.

Best, Martin

Dear All,

For longitudinal data sets, is there a way that the lh.pial surface from the Base can be transformed into the brainmask.mgz space of a Cross so that it can be viewed with tkmedit on the Cross brainmask.mgz?

Thanks,

Paul
