7NBX (lateral-open BAM-LL cryoEM structure) and 7BM5 (Fab1 crystal structure) were rigid fitted into the electron density in UCSF Chimera. One round of molecular dynamics based flexible fitting was then set up in VMD and run in NAMD to fit the structures into the BAM-LL-Fab1 density. The resulting structure was finally real-space refined in phenix to generate the final model.
