Hi! All,
Is there an utility to extract bvals and bvecs from GE’s DTI dicom files into the format dt_recon can use? I try to run dt_recon as it is but it did not pick up those values. Those files are from ADNI.

How is the format different? Is it in 3 rows instead of 3 columns? If so, it should be straightforward to convert it yourself from 3 rows to 3 columns.

Anastasia,
The thing not clear from me is the format for those files. I did not see an example anywhere in the wiki or in the distribution. And I am downing tutorial data now. Hope it is there. BTW, do you have an example? I know how to get those from private dicom tags.

The gradient table has to be in 3 columns for dt_recon. Sorry, I don't have an example because I don't use dt_recon.
