Re: [Freesurfer] R-Map

[Douglas N Greve]

Use this version of mri_glmfit. For t-tests is will automatically 
compute a partial correlation coefficient (pcc.mgh)

[Freesurfer] R-Map

[Morenikeji Adebayo]

Hello Freesurfers,

I'm interested in creating a group map where each vertex/voxel represents the 
correlation (as a correlation coefficient) between a task-related BOLD contrast 
values (ces.nii.gz) and a single covariate. This is analogous to a cortical 
thickness GLM with one group and one covariate, but I'd want an r-map instead 
of a log10p-map. 

How exactly might I do this? I’m trying to accomplish this using mri_glmfit, 
but I’m having generating output that is interpretable in terms of  a 
correlation coefficient and in particular, the direction of the effect.

Thanks,
Keji
