Hi AFNI users,
I would like to create multi sub-brik datasets of DTI data. The data from the scanner takes the form, for example, i*.1 to i*.392 where z-axis is first and then 55 directions.

I treated the data as a time dependent set "to3d -time:zt 7 55 1000 i*" (TR is arbitrary), and then used 3dbucket to convert to the multi sub-brik dataset required by 3dDWItoDT.

Does this sound okay, and is there a simpler, one step method with to3d?

Thanks for your help.
Brian
