Hello all, 

I had a question regarding the program Tracula. I have two different DTI sequences that I wish to run (b=900 and b=2000) but am unsure at which step I am suppose to merge the two sequences together. 

At this point, I have pre-processed each of the sequences separately using trac-all. Should I take each of the separate trac-all output data.nii.gz files, merge them, run bedpostX, and then run the ball-and-stick model fit on the new bedpostX output? Also, is there a way  to use nii.gz files in the configuration file rather than a dcm list?

Thank you in advance for your help!
