Dear Freesurfer Experts,
As it happens for cortical surface mapping I would like to obtain the same for
subcortical structures. I have generated the subcortical surfaces using
fsaverage brain’s aseg.mgz with the tool given in:

When you say deconvolution, what do you mean exactly? There is an FIR model
(finite impulse response) that will extract the hemodynamic response without
any assumptions, ie, the signal average at stimulus onset, the signal average
at 1TR post onset, the signal average at 2TR post onset, etc.

Hi Catarina
I'm not sure how you would do a surface overlay for a volumetric
structure. Where would you map the interior of it?
cheers

Thanks Doug. Another question, how do i find the p-values for voxel-wise
map corrected for multiple comparisons at a voxel (rather than cluster)
level (perm.th40.abs.sig.voxel.mgh). There is no summary file for it.
Best,
Paul

Hi Doug,
I am referring to deconvolution in the SPM sense, where they use (something
like) ridge regression to get an estimate of neuronal activity from the
measured BOLD response.
The idea is to use that neural time series to construct predictors for a

Hello Dear FreeSurfer Developers,
I'm attempting to run some of data with recon-all code, and after some
success run on several data, now I get the following error message even
when I run those data that ran well before:
