dcm4che3 findscu error: ExecuteDBCmd failed?

[Jong Seo Yoon]

Hi Everyone,

I am relatively new to dcm4che, and I am currently trying to migrate from dcm4che2 to dcm4che3.

Since dcmqr is not available on dcm4che3, I am trying to use findscu and movescu on dcm4che3 to achieve the same result as "dcmqr -cmove"

However, I am getting this error when running findscu.

On dcm4che's dcmqr, this does not occur.

I noticed the difference between the two is that dcmqr uses C-FIND-RQ, while fndscu on dcm4che3 uses C-FIND-RSP.

What is the difference between the two? Is it possible C-FIND-RSP is not supported on our server?

Also, I've heard dcm4che3 is still in development and recommend using dcm4che2 over dcm4che3. Is this still true?

Thank you in advance.
