Hi all,
Just wanted to let you know that I was able to fix this problem, in case
someone else has the same issue.
After many tries, even deleting all the restraints and still get the exact
same error, I deleted the scee line and everything went smoothly, including
all my restraints. Now my MD is running without errors. I realised that the
topology file already includes the scaling factor for 1-4 elesctrostatic
interactions, so for some reason, when specifying this, it was an issue.
I hope this helps someone having the same problem in the future :)
Cheers!
Daniela.
