Full-length model built on top templates in LOMETS server

hello. I am an undergraduate student working on a protein structure prediction research project and I used LOMETS servers to predict my protein. This is my first project using computational biology. So, my questions are, why there is no TM-score or C-score for the full-length models? how would I know the best model to use for further analysis? and are the full-length models already refined? do I need to use ModRefiner and validate the structure predicted?.
