Many thanks Bruce, I will choose the best one in this case. The command line was: recon-all -s B_06 -qcache -measure thickness -all (I already had copied by hand the /mri/orig/001.mgz and 002.mgz) Just in case I repeated the process with the original files, but I had exactly the same results.

Hi FS experts, I've run recon-all -i file -s subject -qcache -measure thickness -all to: - 18 subjects, session 1 T1 - same 18 subjects, session 2 T1 and everything went well. Then I copied the /mri/orig/001.mgz-s to /mri/orig/001.mgz and 002.mgz, and run the same command again: recon-all -s
