The standalone I-TASSER (version 3.0), which I recently downloaded and installed on my local server, runs MUSTER which is a protein threading algorithm to identify the template structures from the PDB library. MUSTER generates sequence-template alignments by combining sequence profile-profile alignment with multiple structural information. The online version of I-TASSER builds full-length model by MODELLER. My question now is: how does the standalone I-TASSER compute the models with MODELLER?
