error in step 5/7: importing ROI data

Hi

I was running conn for connectivity analysis. i incurred the following error.
I tried re installing conn and running the project again. but the same error occured.
Could i get some help in this.

RE: error in step 5/7: importing ROI data

Hi Ashwini,

I believe this indicates you are entering multiple files (or a 4d single nifti file with more than one volume) as your GreyMatter ROI (in Setup.ROIs). The GreyMatter ROI should contain a single 3d nifti file describing a mask of grey matter voxels (e.g. if you run the default preprocessing pipeline in CONN this file will be automatically generated and imported during the 'segmentation&&normalization' step of that pipeline)

Hope this helps
Alfonso

Hi Alfonso,

Actually i have not entered any ROI files.
i have just run the default preprocessing pipeline in conn.
then did done in the setup.
what else could be the problem.

thanks
