Hi All,
I created a system and added ions. Used Na+ for neutralizing the system and
K+ and Cl- to add 0.2 M salt. This part of my script:
saveamberparm mol F1KX5-iodFF-KCLNa-SLTCAP-Acy.top
F1KX5-iodFF-KCLNa-SLTCAP-Acy.crd
addIonsRand mol K+ 453
addIonsRand mol Na+ 147
addIonsRand mol Cl- 453
I used "addIonsRand" as I have too many ions to add. This what I have in
log file:
> addIonsRand mol K+ 453
Adding 453 counter ions to "mol". 152781 solvent molecules will remain.
0: Placed K+ in mol at (-66.56, 16.55, 12.03).
0: Placed K+ in mol at (-73.03, -95.38, -46.48).
0: Placed K+ in mol at (52.97, -96.86, -45.80).
0: Placed K+ in mol at (-50.79, 36.63, -55.77).

================================================
Probelm is when I make PDB file fron file.crd and file.top by "ambpdb"
command I can not see any ions when I look at thesysteam by pymol or VMD!!!!
what is the probelm?
