I am a new grad student and have been assigned a project in our Brain Imaging Research Center. I would be taking the time to push through and find these answers on my own but our program gives us 5 weeks of half days in a lab for a trial. So I am in a bit of a time crunch.
I have been given a database of about 500 .nii files and been asked to find duplicates or likely duplicates. (Some subjects were duel-consented so they may have multiple scans.) What is the best way to recon-all all of the files? Individually, in small groups, or in one larger group? If I do it in groups do I need to list each file or can I just recon-all the entire directory? And if a recon-all on 1 file takes 6-20hr, will doing a recon-all on the entire data set take 500*(6-20hr)=3000-10,000hr? Any help is greatly appreciated.

You will need to run 500 different recon-all jobs. Obviously, if you run them on a single computer, it will take a long time, so you will need access to a cluster. Or you can buy time on a cloud service.
