Hi Alan - A nifti file with the gradient tables and b-values embedded? All freesurfer programs can handle nifti volumes, compressed (.nii.gz) or not (.nii). You can pass those volumes to TRACULA, and pass the gradient table and b-value table as separate files.
Run "mri_convert --help" to see all image file formats that we can handle.
Hope this helps, a.y

Hi Anastasia:
I am working on a set of DTI data that were obtained at the Martinos center. The data is in a single nii.gz file. The BVECS and BVALS files are also embedded in this. Could you please advice me how do I code this in the DMRIRC file?
Should I convert the nii.gz file into Analyze to get at the BVECS/ BVALS?
thank you so much,
best regards,
Alan
