DPARSFA Error

Submitted by druzgal on Fri, 11/30/2012 - 02:21

I processed a batch of subjects through the New Segment + DARTEL step and experienced no obvious difficulties. But when I tried to rest a subset of those subjects through the rest of the pipeline, I got the following error:

---------------

Error using parallel_function (line 589)

My version of SPM is current, so the Template_6_2mni.mat files should have been created for each subject. But it looks like the Template_6_2mni.mat file was only created for the first subject run through the New Segment + DARTEL step. When I run that first subject through the remainder of the pipeline, everything runs just fine. Just trying to figure out why the Template_6_2mni.mat did not get created for the rest of the subjects?

Thanks,

Jason

Hi Jason,

SPM's DARTEL tool only saves the Templates file and Template_6_2mni.mat under the first subject's directory. That's why if you only use a subset of subjects (without the first subject), DPARSFA can not find Template_6_2mni.mat file.

Could you perform the following processing with all the subjects, but exclude the subjects when you want to perform statistical analyses?

Best,
