Hi,

I just finished a functional connectivity analysis in subject space using the freesurfer surfaces as structural images and telling the script to use surface-based voxel resolution for the analysis (setting batch.Setup.voxelresolution=4). I am now trying to convert the output BETA maps from the 1st level analysis to a surface overlay to view and do further processing in freesurfer. I'm trying to make sense of the BETA map output format. It says the volume of the output nifti is a 42x83x94 3D matrix, which has the same number of indices as vertices on the surface of fsaverage. How do the values of the nifti volume map onto the fsaverage cortical surface if I wanted to do analysis of vertex adjacent BETA values outside of CONN? Hope to hear back soon, thank you!
