Protein-DNA docking

Dear administrator or anyone,

I am doing the docking between protein and a DNA molecule. I am using the easy interface. When I fill the data, an error is found>

The server encountered an internal error in saving your parameters.
Please send an email to and it will be fixed as soon as possible

Full error information:

I need your help,
best regards

The issue should be solved now - a directory was missing on one of our server.

thanks a lot :slight_smile:
