I'm trying to refine a 3.5 anstrom structure with one TLS and one ADP per chain, but I keep getting the error message: "Sorry: Selections for group B-factor refinement are given, but no refinement requested." The parameters file is listed below. Any suggestions? Best regards and happy New Year, Kendall Nettles refinement { refine { strategy = *individual_sites individual_sites_real_space rigid_body \ individual_adp *group_adp *tls occupancies group_anomalous adp { group = chain X group = chain A group = chain B group = chain C group = chain D tls = chain X tls = chain A tls = chain B tls = chain C tls = chain D }} target_weights { mode = *every_macro_cycle optimize_wxc=true optimize_wxu=true} } refinement.modify_start_model.adp.set_b_iso = 80 refinement.input.xray_data.labels=IMEAN
