Hi Dr. Paul, thanks for your prompt reply.
My AFNI version is AFNI_16.0.18 and Tortoise version is 2.5.1.
I use calcvm to export AFNI and yes, I got DWI.nii and BMTXT.txt. (I do not have IDL, so I use prepvm and calcvm; the titles of the windows are DIFF_PREP and DIFF_CALC).
Issuing the command 3drefit -orient to DWI.nii: RPI -128.000000 100.251221 -85.367073, far away from yours.
Because I'm doing cross-modal analysis, different coordinates become a concern to me. Your code to handle this situation is pretty appreciated. Thanks, JoJo ~
