Hii Everyone I had performed a 100ns protein-ligand (docked complex) simulation with gromacs 5.1.4. The ligand in my case is hydrogen peroxide. I have removed the PBC effect and centered the protein. I have used the following commands: gmx_mpi trjconv -f md.xtc -s md.tpr -pbc nojump -o

Dear all, I want to keep a water molecule at a particular position of a protein channel. I need to pull this across the channel and observe the energy diagram by PMF. can anyone tell me how I can keep water molecules at a particular position. thank you. -- Gromacs Users mailing list * Please

Dear all, I am trying to make a model of ion channel with cell membrane. Is there a specific software to make this? I mean just the coordination file. VMD can generate the membrane automatically, I can find the 'pdb' files of ion channels, but I have no idea how to combine them. Thanks all,

Dear GROMACS Community, First of all, if someone got this email twice, I am sorry. It is my first post and I was not sure if it worked. I am trying to do a simulation using a tabulated potential which forces me to use the group cut-off. I get a drift in the conserved quantity of
