[gmx-users] Re: Continuing a simulation plus another error

[Ankita naithani]

Hi again,

Sorry for the repetition in email.

When I ran the mdrun command, I got an error of

"Attempting to read a checkpoint file of version 13 with code of version 12"

Can anyone please help me with this error too?
