Hi! 

I am trying to generate 2d diagrams with Dockview  from autodock vina outputs but I get this problem : 

Web Service: cdkdepiction converts either SMILES strings or MOL2 files into 2D structure diagrams in PNG format
Opal service URL: http://webservices.rbvi.ucsf.edu/opal2/services/CDKDepictionService
Opal job URL: http://webservices.rbvi.ucsf.edu/appCDKDepictionService1586137005272-807576004
CDKDepictionService stderr
-----
Error: Unable to access jarfile /usr/local/cdk/CDK-Depiction.jar
-----
CDKDepictionService stdout
-----
[no output]
-----
Structure diagram generation failed; see Reply Log for more information

Any suggestion or needed program to install? 

Thank you !
