Hi Matthieu
did you check the talairach registration as suggested? ALso, make sure that your input volume has the correct direction cosines (that is, that what freeview thinks is anterior is actually anterior, etc...) cheers Bruce

Dear FS experts,
I got no answer to my question. Could anyone explain me what is the problem and how to solve it ?

I am confronted with some problem in the "recon-all" of a few subjects concerning Talairach space, but don't know how to manage these.
Please find below the recon-all log with errors :
