[Mristudio-users] a question about gradient table in dpf file

Hello,

I have downloaded DtiStudio latest-x86.exe version. While I am processing
the DTI data acquired in 26 non-collinear directions using DTI Mapping, an
error occurs saying that MriView3D MFC Application has encountered a problem
and needs to close.

Please suggest what to do.

Thanks

Sona
