Dear all,
I am trying to run probtrackx2 (GPU version). I am using ROIs from an atlas which I registered to the subject diffusion space using ANTs and then I copied the header information of the subject diffusion image using fslcpgeom.
When I try to run probtrackx2_gpu it gives me this error:
terminate called after throwing an instance of 'std::runtime_error'
what(): inv(): matrix seems singular
If I use the CPU version of probtrackx2 it does not give any error.
I am running the following command:
probtrackx2_gpu -s "$data_dir"/bedpostx/M1/"$SUJ"_M1.bedpostX/merged -m "$data_dir"/bedpostx/M1/"$SUJ"_M1.bedpostX/nodif_brain_mask.nii.gz -x "$out_dir"/"$MRI_ID"/seed_targets.txt -l -P 5000 --forcedir --opd --dir="$out_dir"/"$MRI_ID"/ -V 0 --omatrix1
I hope anyone could help me solve this error.
Many thanks in advance,
Ana
