Error with deterministic fider tracking
Dear community,

I'm trying to run deterministic fiber tracking on HCP preprocessed data. To do so, I opened the "Tracking and Network" from the PANDA utilities. in the Native Folder, I put the path to a folder containing my data.nii.gz, bvec, bval and nodif_brain_mask.nii.gz as specified in the PANDA manual. I have then checked the "deterninistic fiber tracking" box leaving all default settings. After, I simply press run. However, I'm running into an error immediately after launching which says the following.

Please help me!


Thank you
