Dear Fsl Team,
when I try to register my direction results (calculated with another program (Mrtrix)) to a template I got following error message:
vecreg -i peak1_reorientated.nii.gz -o peak1_reorientated_registered.nii.gz -r FA_mean.nii.gz -t FA_registered.mat
Registering vector...
libc++abi.dylib: terminating with uncaught exception of type NEWMAT::ConvergenceException
Abort trap: 6
I guess it has something to do with the fact that the orientations are not calculated via fsl. But the direction files have the same structure as the dyad files! 4d files with 1dim=x 2dim=y 3dim=z and 4dim=1st. volume x-coordinate of given vector; 2nd. volume y-coordinate of given vector; 3rd volume z coordinate of given vector! They are able to load into fsleyes without any problems! The only differences compared to the dyads is that the orientations are not normalised to 1.
It would be so nice if somebody understand the error message and could help me to fix the problem!
Thank you very much.
Best
Max
