!important; } Dear justin
I am tryinig to analyz minimum distance between periodic images, so need a new
.xtc file which has not jumps. I isseued this command:Gmx trjconv -s .tpr -f
.xtc -o new.xtc -center -pbc molI didnt need to create an index file, because
my protein and peptide ligand are merged. But when I bring the .gro and
new.xtc files to vmd, the new.xtc file has just a frameWould you please help
me how come this xtc file has just a frame and what kind of command I have to
issue to generate a new one?
Thanks in advanceFarial

In the absence of your exact sequence of commands, there's nothing to
say other than you've probably lost track of what you (think you) are doing.
