Hi Nabil,

yes, it seems we are experiencing problems with the connection with our internal PDB database mirror. Please try to download the PDB file from the [PDB website](https://www.rcsb.org/) and use it as an input file in the server.

Sorry for the inconveniences. The issue has been reported.

I would also recommend to take a look at the [BioExcel Building Blocks](http://mmb.irbbarcelona.org/biobb/) (biobb) website, which is a more recent library that can help you on the MD setup and run processes.

Thanks for your interest in our tools!

Regards,

-Adam-

Hi Imam,

we are still working on solving the internal PDB mirror issue, but the server should work with a PDB structure. Can you tell me in which PDB file are you interested so that I can reproduce the error?

Thanks,

Hi Imam,

PDB 6lu7 is working in my side. Please try to upload the PDB file into MDWeb and leave the “_Swiss-Prot or PDB Code Id_” form empty. Maybe this is the problem you have.

Contact me again if it is still not working for you.

Thanks,

-Adam-
