looks good

The command line is correct?
Yes, though I'm not sure about the effect of using --wls and --pvr. I guess it will be ok, I just have not used it.
My concern is on the fsgd file.
I have
GroupDescriptorFile 1 Title All Class Main Variables thickness Input ADNI0XX_GROUP1 Main ???? Input ADNI0XY_GROUP1 Main ???? Input ADNI0YX.GROUP1 Main ???? ...
What I should add after Main if I would like to assess the vertex by vertex correlation between FC (between seed and target vertex) and thickness (in the target vertex)?
Don't represent the PVR in the FSGD file. You only need to include items in the contrast matrix. Eg, for intercept use [1 0] and for slope use [0 1] eventhough you only have a single class.
Should I add the path where is contained rh.thickness.mgh of each subject?
No
Please give me an help because I did not find these information using --help or mail list.
Thanks
Stefano

Yes, use the --pvr option to mri_glmfit (per-voxel regressor). Search through the mail archives for an example on how to use it

Hi list,
Is there a way to obtain a map that report the "vertex by vertex" correlation between the FC (obtained by FS-FAST) and cortical thickness?
Thanks
