MD scripts and tools

When organising my files, i came across some scripts and a modified g_density for gromacs 4.07. I made them during my research project at the md group on the influence of certain substances on the membrane. Feel free to use and modify them since that’s mostly how I obtained them in the first place.
gmx_density, modified to properly centre on electro density, gromacs 4.07
