I have some statistical results for AAL 90 coordinates (correlation coefficients from network measurements x clinical data).

 

I would like to create an overlay to visualize in FreeSurfer standard (fsaverage) space, showing the areas with positive and negative correlations (and the scale / power of correlation, i.e. beta-value, for each area).

 

Is it possible using FreeSurfer tools? If it is possible, how should I produce a .txt file to be read in FreeSurfer.

 

Kind regards,

Carolina
