Hello!
I have resting state data acquired with the following scanning parameters: TR 2.3, vox size 3x3x3, and I am doing an analysis using DPRSFA V_2.1 and Matlab 2015b. I am reslicing the voxel size to 4x4x4 during the normalization step (this is so I can compare this data with another resting state data set at the group level). I am getting an error while doing the Nuisance Covariates Regression with CompCor and the step is not completed. Would anyone know what the problem is?
Steps I did:
Remove first 10 time points
Realignment
Coregistration
Segmentation (Segment)
Normalisation (using T1 Image unified segmentation; Voxel Size: 4x4x4)
Nuisance Covariates Regression (Rigid Body 6, method: CompCor)
I am getting the following error:
Error using y_CompCor_PC (line 52)
Index exceeds matrix dimensions.
Error in DPARSFA_run (line 2457)
parfor i=1:AutoDataProcessParameter.SubjectNum

Error in DPARSFA (line 30)

Thank you in advance for your help.

The nuisance masks are not
The nuisance masks are not the same voxel size with your data (4x4x4). Please reslice them first.
Thank you for the answer!
Thank you for the answer!
Could you please write, where can I find the masks and how (and at which point) can I reslice them?
Is the 3 3 3 voxel size the default one for the nuisance masks ? I didn't get the error when I used CompCor with 4 4 4 voxel size data sets after normalizing them with DARTEL - is the analysis incorrect then?

Then just use DARTEL. Should
Then just use DARTEL. Should be OK.
