Hello FreeSurfer experts, I am doing volumetrics study. During the scan we get 2-3 mprage per scan for a subject. While running the FreeSurfer, if I want to use the three mprages for that subject as an input file, may I just keep the three mgz files (001.mgz, 002.mgz and 003.mgz) in the orig folder and run the simple recon all command :Recon-all –s (subject file name) -all or do I need to have some additional flags so that recon all command will use the three T1 images to get one output file? Thanks, Rashmi
