Molecular dynamics

Hi,

I would like to perform metadynamics to a gpcr bound in a lipid bilayer to a protein ligand which I docked to the receptor. From a paper I know the structural differences between the active and inactive receptor.

From what I understand would be good practice to:

- Show that running unbiased MD does not show the activation of the GPCR.

- Run also the receptor without any ligand to show the energy difference with and without the ligand

- Run a negative control with a protein who supposedly does not activate the receptor

- Run the MD in triplicates.

Since keeping up with all these practices would mean a lot of computational power that since I am using my university HPC that implies a lot of queuing and stuff. How long should i run unbiased and meta md? Should i do triplicates? Is it really important to run a negative control?

And for the one experienced in metaMD, how do i pick a CV that makes sense? And other tips?
