Hi Laura,

the .gcs file is a probabilistic atlas with lots of information such as neighborhood clique potentials. You are probably better off applying it to fsaverage and computing the centroids of parcels in that space.

Hi all,

I have a question about how to get a .nii or .mgz file out of a .gcs. What I actually want to do is get the coordinates of the centroids of the regions of my atlas ( which is lausanne2008), or even the coordinates of all the voxels in each region so I could compute the mean myself. However, I only have the gcs files (myatlas_125_rh.gcs and my atlas_125_lh.gcs) and have no idea on how to get this information.

Thank you a lot in advance.

Laura
