Hi freesurfer team, I am wondering if there would be a way to process a glm analysis between 2 surfaces from different modalities within one group of subjects.
For example, within one population of patients, we would like to see if there is a spatial relationship between cortical thickness and another metrics (DTI metrics for example). What we have done so far is compute the mean cortical thickness for each parcellation, the mean FA for each parcellation, and we did a linear regression with all the subjects of our group. Would there be a way to do that at the vertex level instead of a whole region level? From what I understood, when we use glmfit, the regressors that we can put are single values like age, group, cognitive testing etc, but maybe not an entire surface?
