[gmx-users] MD run complete but ligand not showing up

[su]

Hello
I am confused about my MD results.According to Justin's tutorial of protein-ligand MD, i performed short 1ns md on my protein-ligand system. After completion, when i opened up the md.gro and md.xtc in VMD, it is only showing up protein.Ligand is absent from box. Also, no .trr file is generated. When i tried to view hydrogen bond interactions, it gave fatal error that no topol.trr is found. I have also prepared movie.pdb and viewed it in pymol, but in that also ligand is not showing. Can anyone please tell me if this is a common error? do i need to insert the ligand gile manually? I can attach the files if required.
Regards
Suniba
