[gmx-users] structure factor units

[Juliette N.]

Dear all,

I have attached the structure factor plot for my polymer in solvent system
using the last 500 ps of my runs. I am using System when index file

prompts for the group number, However, my plot is not smooth as can be seen
form the attached image. Do you have idea
if this is normal? Also can anyone let me know what are the units?

 g_rdf -f *.xtc -s *.tpr -n *.ndx -sq System


Thanks for your help,
J.
