Hi all, I am trying to run grompp on POPC lipid bilayer that I constructed in CHARMM-GUI. I originally input the whole assembled bilayer from CHARMM-GUI, however, I received the error: "No Default U-B Types" >From a few previous threads, it was suggested that I stripped the waters and use pdb2gm

[gmx-users] Setting Up "Equivalent" Runs With -notunepme

Hi everyone, From my understanding of the release notes for the gromacs-2016 versions, pretty much all of the settings that are tuned by tunepme can now be modified manually (modifying some of these settings still caused errors all the way up to gromacs-5.1.7). I'm not trying to make runs th
