Sorry, I wasn't clear. It's a cortical label that I manually created, based on the pial surface.

Is it possible to generate the corresponding WM vol based on a new label (not pre-defined)?

I don't understand. What label do you have? Do you mean a WM label or a
cortical label that you want to find the WM under?

Hi Doug,

I am able to find wmparc.stats in stats. It shows WM vol based on
pre-defined ROIs.

However, do you know how can we generate corresponding WM vol for a
given label (not the D-K ROIs)?

I'd like to use WM vol as DV but are limited to pre-defined ROIs.

Best,
Daniel

     It should be there if the recon did not fail. The file is called
     wmparc.stats (not wmparc_stats.txt)

         Thanks, Doug! But that is about using wmparc.stats as IV or
         continuous/covariate variables. I would like to use WM vol as
         the DV
         (measure).

              you can just add them into your qdec file (from wmparc.stats)

                  Dear FreeSurfer Experts,

                  FS provides thickness as the DV in qdec and
         mri-glmfit. Do you
                  know how I can have WM vol as the DV in these tools
         with the
                  same GLM model? For example, I want to test the WM
         regions
                  that is most strongly positively correlated with a
         given factor.

                  Thanks!
