there won't be any interferance if you use -openmp 1 (which I think is the default) as long as you have more processors than recon-all jobs (and enough RAM to support them all)

One question about "-openmp". If I run multiple "recon-all" in different

Is there any problem with the 'gcareg' stage? For example, is there any
interference between subjects reconstruction?

      Hi Linda

      did you actually include the angle brackets?  If so, try without
      them. And
      don't you want 4 there instead of 8 (if you have 4 processors)?
