[gmx-users] adding extra ions to charmm gui output

[Nikhil Maroli]

Dear all ,
For studying transport properties of the peptide tube  have made system
using charmm-gui.later i added three pottasium ion  inside the channel
using YASARA software and added sufficent neautral charges.neccessary
entries are made in topology and atp,itp (ff is charmm 36). when i execute
grommpp command im getting the following error

"Box Was Shifted at least 10 times,please see the log file."

welcome suggestions !


system was cyclic peptide nanotube in pope lipid bilayer-

i wanted to add extra ions at the top ,miidle and bottom of the tube to
study the transport properties .
