[Freesurfer] Pre-processing issues

Dear Bruce,

I have two more questions for today, please: 1). Just to be sure that  I understood correct: for my  cortical thickness studies and also for a group studies analysis I will use only the data from the 3DAx_T1series which was converted to a .nii.gz file. Is this right?

2). If I want to shortness the pre-processing time while running the recon-all for my subjects, can I run recon-all for three subjects  by opening three terminals in the same time? Running more subjects in the same time will induce more errors for a manual correction or the results will be the same with the one while running each subject individual/only one terminal at the time.

Thank you and have a great weekend. Antonella
