Hi Sal - The 0's should be included as before. Can you send an example of these bvals/bvecs file that are causing this problem? If they are also formatted in rows as with your other example, I'd also check for spaces a the end of the lines.

Thanks! a.y

Hi, I have been trying to rerun cases through the new (12/13) tracula code, which I had successfully ran through the pre 12/13 code. While I am still trying to sort out the libnetcdf.so.6 issue on our cluster, I also noticed that cases which I ran using the bvec and bval files including 0's for the b0 files were processed with the old code, but result in a xx:subscript out of range error in the current code. Removing the b0 entries fixed the problem and the remainder of the processing (other than the part requiring libnetcdf.so.6) works. I did notice that the bvecs and bval files in the diffusion tutorial do include the b0 0. Does the current version of tracula require the b0 entries to be removed? If not, any suggestions on what I may be doing incorrectly would be great.

Thank you.
