Problems with bvecs files for NYU longitudinal data sets
Hi there,

I am working with the ABIDE II data set for DTI analysis. I am running a number of analyses on 5 of these data sets, including the NYU1 and NYU2 longitudinal sets. We are trying to run TBSS with this data, however there are two separate bvec files associated with the download (dti.bvecs_absolute and dti.bvecs_image). We're not sure which of these to use and since we don't have access to the original DICOM files, we have no way of generating them ourselves for each subject. Is there a difference between these two files? How do I know which one to use?

Any help is much appreciated!
