Thanks for the quick reply.

The weird part is that in my original PDB, the TER lines (6 in total) are not followed by anything. They just read TER.
After performing mutations with modeller and saving the file, the output of the 6 TER lines has additional columns.

Is there a particular reason for modeller to be doing this? (I can provide the input file and output files)

You are incorrect - Modeller writes correct TER records; see
