[gmx-users] gmx dens charge

[anupama sharma]

Dear users,
I need to know for charge density calculation specially for water, should
we use -center /-symm option or not and if not why?
Since I tried the option (-center/-symm) for charge density calculation of
water and gmx dens module was not reading frame. I used the gromacs version
5.1.4 for the analysis.
I will be highly thankful if any one can suggest me regarding this.
