Dear Gmxers, I want to simulate 5M nabr aqueous solution.To add the ions I use genion command and add 22 na and br ions respectively to the system of pure 108 water molecules.But on running the command genion I get error message
Processing topology Back Off! I just backed up topol.top to ./#topol.top.9# Replacing solvent molecule 12 (atom 36) with NA Replacing solvent molecule 52 (atom 156) with CL Replacing solvent molecule 35 (atom 105) with NA Replacing solvent molecule 17 (atom 51) with CL Replacing solvent molecule 41 (atom 123) with NA Replacing solvent molecule 70 (atom 210) with CL Replacing solvent molecule 44 (atom 132) with NA Replacing solvent molecule 66 (atom 198) with CL Replacing solvent molecule 34 (atom 102) with NA Replacing solvent molecule 29 (atom 87) with CL ------------------------------------------------------- Program genion, VERSION 4.0.7 Source code file: ../../../../src/tools/gmx_genion.c, line: 85 Fatal error: No more replaceable solvent! ------------------------------------------------------- How should I add ions in the system.I have tried doing it but could not get it please if someone may point my error. -- DeepaK Ojha School Of Chemistry "Selfishness is not living as one wishes to live, it is asking others to live as one wishes to live" -- gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.
