If you want to create statistical maps in surface space, then use mris_preproc to assemble the data. Then use one of the FSL tools to do stats or use mri_glmfit. You cannot do corrections for mult comparisons on the surface with the fSL tools.

Hi all,

When I overlay functional data (e.g. from FSL) onto a Freesurfer-produced inflated brain, I see the activations shown in colors. I want to pick a voxel in Talairach coordinates in those activations and see how the particular voxel's activation level changes throughout different data sets of the same brain. So, my question is how can I get the activation level of a particular voxel consistently throughout different data sets, so that I can do some sort of statistical tests?

Thanks in advance.
