Thanks Anastasia - that was very helpful. I have another question :  I am working on a DTI dataset of around 70 subjects. This dataset has ostensibly only 1 set of BVECS/BVALS. Can this set be 'generically' used for all the images, given that they have been acquired on the same scanner?

 

thanks,

 

Alan

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
