Re: [Freesurfer] Labelling SurfStat p-value surface map

External Email - Use Caution

Hi Bruce,

I am coming back to this request as I was wondering: would it be possible to load freesurfer surface atlases in surfstat in order to label my surfaces? Is their format compatible? I saw surfstat only accepts a limited array of formats...

Thanks, Best,

Loïc

sure. All the fsaverages are in the same space (they are subsets of fsaverage) On Mon, 20 May 2019, Loïc Daumail wrote:

  Hi Loic

  if you are on the fsaverage surface you can save the -log10(p)

values

...

  using save_mgh.m, then load them in freeview and threshold them or
  whatever

  cheers
