If you don't mind me asking, what kind of file is it? The PBCtools plugin has a "readxst" command ( that can read in external files with the PBC information in a specific format. Or if you knew your format, you could write your own Tcl parser to read the files line by line in an automated way.

Aha, now I'm getting it. Yes, it looks like you're right. I have seen a couple of posts elsewhere online that are suddenly making sense. Those people must have had their cell/box dimensions at each time step IN their trajectory files. I have my cell/box dimensions in a separate file. So I need to figure out how to combine my cell/box file and trajectory files.
Thank you very much for that explanation. This is finally making sense.
