Dear expert

I'm beginner in using Freesurfer and I really need your help.
However I've read all related responded questions about paralleling process. I found -openmp N flag to do that, but I don't understand its correct location in 'recon-all'. I used it as follows but it doesn't work. Also I want to use -qcache flag in addition to -openmp N. Would you please kindly let me know in which order, these flags should be used? I really appreciate your kind help.
