First of all a huge thanks for such a nice and intuitive tool!

My first few preparations and runs went smooth, but now whenever I try to prepare a protein for either Gromacs- or NAMD MD, the service gets stuck at the “minimizing hydrogens” step. Even when I use exactly the same pdb file, as I used the first time when it worked.  
Is it a problem on my side, or?

Best, MikaelW

Hi Mikael,

that was due to technical problems on our side. It should be solved by now. Please tell us if you are still having problems.

Thanks for your kind words and for your interest in our tools!

Don’t forget to look at the BioExcel webpage for updates on our MD tools!

Best!
