Hi,
   When I run selxavg3-sess, I face this error:

ERROR: cannot find volume matching /autofs/cluster/tootell/pitcairn/1/shahin/ColorPrj/7T/Sbj/myla2/bold_Color/013/mcextreg
ERROR: loading nonpar reg /autofs/cluster/tootell/pitcairn/1/shahin/ColorPrj/7T/Sbj/myla2/bold_Color/013/mcextreg
------------------------------------------
ERROR: fast_selxavg3() failed\n

  I repeated the preproc-sess from scratch and it worked fine, finished without any problem and I still get the same error.  I even check the registration in this run and it fine.

  Now I am wondering why do I see this error for this subjects (and why I don't see it for the other subjects)?

Regards
