DPARSFA Error Related to Number of Parallel Workers

Submitted by druzgal on Tue, 09/25/2012 - 01:57

Hi,

I have been testing some of the features on DPARSFA V2.2PRE. When running on data from either 1 or 2 subjects using the options from "Calculate in MNI Space: TRADITIONAL Order", everything processes smoothly with parallel workers set at 0. However, when I set the parallel workers to 6 (on an 8 core machine), I get the following error:

Thanks for making such a nice processing pipeline available. Just hoping to be able to use more of the parallel processing capability!

I think you added with subfolders for installing REST.
Could you try to avoid add with subfolders but only add folder for installing REST.
Please have a try, and DARTEL - create template will not be parallel processed since it's not parallel across subjects.

Best,
