Dear @Connor-Bowley, @Hoai-Nam_Bui, and @bpaniagua,
I hope you all doing well.
Actually, I am still facing the same issue - even with the latest version of SlicerSALT 4.0.1.
After uploading the required material [I got no response - and no error message].
I agree with you that there is a need for detailed-tutorial, with a case, that outline the pipeline for the “correspondence improvement module”.
All the best.
Regards,
Sultan
