Sure thing.
I also forgot to mention that dcm2niix is now distributed within AFNI as "dcm2niix_afni"-- the name is different just to avoid conflicts with any versions you might have on your system already. Thanks again to C. Rorden for making that happen!
And as ever, sometimes funky things can happen converting dicoms to NIFTI, even with the best of tools. So, it helps if you can check a row or two, for example making sure that the b-value comes out correct (esp. if the sequence is "home-designed" on your scanner). You can add a "-out_col_bval_sep FILE" output to get a separate output of just the b-values, one per row in a text file. I also have a gradient viewer program I have been working on; still finishing it so it isn't in the released distribution, but we can discuss more about that if something looks potentially funny with the grads/matrices.
