There is no magic way to "get rid of PBC", and "-pbc whole" is certainly
not it. Read trjconv -h and see
for suggested workflows.

There is no outside. Since your ligand and your protein were probably
not part of the same [moleculetype], "-pbc whole" can't magically
understand you think they should be represented relative to the same
periodic cell. Correct usage of "-pbc cluster" might help.

We can't possibly know.
