[gmx-users] finding charges and radii

[Shuaib Shahid]

Hi,

i am very new to VMD and gromacs so this question will probably sound very basic.

I have a file of lipids "pop128a.pdb" and i wanted to know how i can find the charge and diameter of the headgroups in this and other lipid files. can i do this in VMD or should i be using another program, such as gromacs, to find this?

thanks
