for some reason the "Get Gradient Table" button is inactive for me!!! I have no idea why!

How about using the button Get Gradient Table directly in DTIstudio? It works well with enhanced dicom, should be the same with old-style dicom.

is there any other (easier) way to do it? the way I do it now is running
dcm2nii on my dicom files to get the bval and bvec files, but I also
have to transpose the table since MRIstudio format is not consistent
with MRIcron. Could you please explain what do you exactly mean by
recalculating the table?! I thought what's in the .dcm file header is
the correct gradient, am I wrong?
