[gmx-users] Pulling Simulation Query

[Natalie Stephenson]

 Hi ...

Just wondering if there's a way, during pulling simulations, to immobilise say the C-terminus of the protein.

I've been running through the 'Umbrella Sampling' tutorial with my own protein.  Within this tutorial the ChainB is used as the immobile reference - so it is this that is position restrained.  Is there a way of position restraining just one amino acid? How would I specify that in the topology file?

Thanks
Natalie
