Dear. All.

Hi. How are you?

It might be a very naive question, but your advice is greatly appreciated!

I'm trying to register 2 T1s obtained from 1 subject on different days and then register the functional scans to their corresponding T1s (registering the functional scans to the same day's T1). By doing so, I expect to get everything into the same space.

(Each subject was scanned twice on two different days etc., day1 and day2)

After running mri_robust_register onto day2's T1 as targetting day1's T1, I get v2to1.mgz (original T1 is 046.mgz). Then I'd like to run preproc-sess(that does registration as well) onto day2's functional scans.

Is there a way to make preproc-sess do register functional scans of day2 to v2to1.mgz(of day2 that's created by mri_robust_register), not the original 046.mgz?

The commands that I run are:

recon-all -s $SUBJECT -all

mri_robust_register --mov /home/jbang/Projects/replay/mri/replay10/mri/orig/046.mgz --dst /home/jbang/Projects/replay/mri/replay06/mri/orig/036.mgz --lta /home/jbang/Projects/replay/mri/replay10/mri/orig/v2to1.lta --mapmov /home/jbang/Projects/replay/mri/replay10/mri/orig/v2to1.mgz --weights /home/jbang/Projects/replay/mri/replay10/mri/orig/v2to1-weights.mgz --iscale --satit

preproc-sess -s $SUBJECT -df sessdirfile -fsd bold_sponta -per-run -force -fwhm 0

Please feel free to give me any advice!

Thank you very much.

Best,

Ji Won
