[gmx-users] spatial distribution function (SDF)

[Dallas B. Warren]

First three groups are the reference group, from which the SDF is generated, it sets the coordinate system.  That means you need to have at least three "atoms" in the "molecule" you are generating the SDF from.

Hai all...

Did anyone know how to do spatial distribution functions??? I have 125 ion pairs in my system. The problem is, 

1)how I can I get the 3-D probability distributions of anion around cation or cation around anion in my system? Could anybody tell me the method? 
2)When I read the GROMACS manual, I should create 4 group in my index file. Can anybody tell me what is first, second, three and for group represent??? I already try to do it, but  I'm failed to get the result.. 

Thanks 

IMA
