Dear Free Surfer team,

I keep trying to run -autorecon2 but it seems that I should have run recon -all -all instead as I am having problems with the names of my subjects and the same error appears once and again and I do not know how I should do it so I do not miss the lables of my participants. I have a sample of 114 participants divided and 3 groups. Every group has numbers from 001 to 038 and they are in different folders such as subjects, subjects_post and subjects_controls. Now, I after visual inspecting that autorecon1 was fine, I am trying to run -autorecon2 and I keep with the same message:

ERROR: You are trying to re-run an existing subject with (possibly) new input data (-i). If this is truly new input data, you should delete the subject folder and re-run, or specify a different subject name. If you are just continuing an analysis of an existing subject, then omit all -i flags.

I wonder if I have to change or rename my subjects in order to be able to run autorecon2, or I should begin again with recon -all -all, as it seems I would not have any problem with the names of my participants.

I would much appreciate your helping on this.

Yours sincerely,

Rosalia
