Hello FSLers,
I performed the FIRST analysis using run_first_all via this link: https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FIRST/UserGuide, and once completed, I used fslstats to gain volume. I was wondering if the data is normalized when using fslstats.
Also, I obtained differences between groups in volume but I would like to also have a visual representation of these differences and show that subcortical nuclei are larger in the healthy brain than in the patient brain. Should I use fslmaths to get the average of the images gained from FIRST of each group or should I use fslmerge? I’ve tried fslmerge but get errors involving issues with different dimensions.
Any help would be most appreciated!
