[gmx-users] Internal Density

[abdullah ahmed]

Dear all, 

I have 2 structures similar to a Beta-turn where the inside is hydrophobic, and I would like to find the density of just this part of the strucuture. More specifically, 
both structure are identical expect for one mutation. One of the structures contains 2 glycines facing each other and the other contains a glycine facing a tryptophan.  
I would like to know if there is a functionality in gromacs that can measure the difference of density between the two strucutres. 

Thank you in advance,
Abdullah
