[Freesurfer] ROI labeling?

Hi again Freesurfers, I am doing a surface based ROI analysis where for each subject, isomorphic ROIs of 300 vertices (centered around peak functional activations) were found on the fsaverage surface space. I was wondering if I should register these masks that I have created back to each

Hi Freesurfers, I am doing a surfaced based ROI analysis on each of my subjects functional data. Using information from other papers, the size of the ROI really matters when doing the analysis, and I want to take this information from these papers and apply them to my own data. However, these

?Hi list, I am trying to run mri_glmfit on a group of subjects using the --frame-mask flag because I want the design to be changed based on which subjects have a value at a single voxel. This is because I have one subject in my group whose signal was cut off through parts of their occipital

Hi List, I am currently doing a group analysis of 26 subjects, one of which has missing fMRI data where the signal cuts off through parts of the occipital and temporal lobes. I was wondering if freesurfer has any way of dealing with this, such as multiple imputation, or other methods of
