The resulting .xtc file from unigbsa-md had not water molecules and ions. How to include water molecules and ions in .xtc file. Moreover, when processing pbc with unigbsa-pbc command, I received the following error:

You can save all files during the MD process by adding the -verbose parameter. And the outdir/complex.GMX/md.xtc is the trajectory contains the water molecules and ions. As for the error you mentioned, could you please provide all the files you run（md.tpr, md-pbc.xtc and index.ndx）?

Ok. I am very glad to receive your reply! Could you further introduce the differences among md.xtc, md-pbc.xtc, and traj_comx.xtc? Does traj_comx.txc have removed PBC? 发件人：Maohua Yang ***@***.***> 发送日期：2024-10-25 16:34:52 收件人：dptech-corp/Uni-GBSA ***@***.***> 抄送人：Wanggang ***@***.***>,Author ***@***.***> 主题：Re: [dptech-corp/Uni-GBSA] The resulting .xtc file from unigbsa-md had not water molecules and ions.

The md.xtc file is the original output trajectory file of the md production. The md-pbc.xtc and the traj_comx.xtc file are the same file in different floder and name. The md-pbc.xtc file is the md.xtc file with PBC removed, and the traj_comx.xtc is a copy of md-pbc.xtc file.

I see.
