[Camino-users] tractography

[Curci Marina Carmela]

Hello to everyone!

I'm new on camino and I'm trying to use the toolkit with my DTI dataset.
I have some problems during the tractography.
The mask I'm using it's a mask of the white matter obtained with Freesurfer. Physical dimensions are the same of the file containing the tensor, but resolutions are different.
When i try to launch track command I have this kind of error:


track -inputmodel dt -seedfile /home/marina/Desktop/fsmask_1mm_resamp2x2x2.nii.gz -curvethresh 60 -inputfile DTI_RAWDATA/difftensor_nomask.Bdouble -outputfile DTI_RAWDATA/traccia.Bfloat

I'm not able to find where is the problem. Could you help me please??

Thank you,
Marina
