Re: [gmx-users] Bound water calculation (Justin Lemukel)

2016-11-07 Thread Abhishek Gupta
Hello, I want to calculate the number of water molecules participating in inter chain hydrogen bonds between multiple chains that are associating in concentrated aqueous solution. My system contains multiple polymer chains, water molecules and counterions. I also want to calculate the bound water

Dear Gromacs Users I want to examine the distribution of counterions in my system at larger length scales comparable to the size of the molecule. I have used RDF's to find the distribution of ions till half the box size. Can I consider half the box size as larger length scale ? I have found in a

Dear all, I have used the radial distribution functions to examine the structure and distribution of ions in the proximity of the polyelectrolyte and studied the spation distribution of ions at the smallest length scales. I have to now examine the distribution of counterions at larger scale as

Re: [gmx-users] Unable to visualize my Polymer chains in VMD software generated using RIS theory in a proper way

2016-03-11 Thread Abhishek Gupta
Dear GROMACS Users, I am trying to visualize the simple polyethylene chains (multiple chains) consisting of certain number of atoms generated using RIS theory using VMD. I'm using the PDB format to express coordinates to visualize my chains. The chains are very random and at some points multiple
