External Email - Use Caution
Helloo,
I have 2 sets clinical scans on a single subject that I put through Synth_SR. The Synth_SR tutorial suggests that if you have T1, T2, and FLAIR scans, you might want to average the number of voxels when doing ROI analysis. I want to apply this logic to cortical analysis.
My idea is to "average" the cortex of T1, T2, and FLAIR scans from year 1 and year 2 using the longitudinal pipeline. Then I'd like to compare the "-base" images from both sets. Previously, when I've tried using the "-base" images in a study, I get the error that says something to the effect of "It appears that this subject ID is an existing base/template from longitudinal processing (-base): xxxx. If you are trying to re-run a -base template you need to pass the -base and all -tp flags:...."
So, is it possible to do a longitudinal analysis on 2 "-base" images, or is there a different method you might suggest?
Thank you all.
