Hi, there,

I have question about the mris_volmask ERROR.

I ran multiple subjects on our SUN Grid Engine system. sometimes some subjects are sent to the same cluster node, and limited memory is assigned to each subject. Because of this, I often met an ERROR at the mris_volmask --label_left_white 2 --label_left_ribbon 3 --label_right_white 41 --label_right_ribbon 42 --save_ribbon --save_distance sub1 step in autorecon3., which gave me an error like:

ERROR: In /usr/pubsw/packages/vtk/5.2.0/src/Common/vtkMultiThreader.cxx, line 372 vtkMultiThreader (0x33d05a90): Unable to create a thread. pthread_create() returned 12

I knew this error is caused by some VTK function FS used to allocate memory. What I did is everytime when I met this kind of error, I use recon-all -s subj -autorecon3 -no-isrunning , and the process will finish.

However, I found if I did something like this, it will cause problems at the wm parcellation step. For example, I have the same subject which is sent to SGE, fails at mris_volmask, and then I call autorecon3 to finish the process, and I go to wmparc.stats, lotf of rois such as isthumus ctx-cingluate, ctx-posterior singulate are 0. While I ran the same subject at a local machine, and finished without any problems, I looked at isthumus cingluate and posterior singulate, they are not zeros.

So, does it mean that I need start from beginning when I met the errors cause by mris_volmask?

Thanks a lot! guang _________________________________________________________________ Chat with Messenger straight from your Hotmail inbox. http://www.microsoft.com/windows/windowslive/hotmail_bl1/hotmail_bl1.aspx?oc...
