{"doi":"10.1107/s0108767390010224","title":"Improved methods for building protein models in electron density maps and the location of errors in these models","abstract":"Map interpretation remains a critical step in solving the structure of a macromolecule. Errors introduced at this early stage may persist throughout crystallographic refinement and result in an incorrect structure. The normally quoted crystallographic residual is often a poor description for the quality of the model. Strategies and tools are described that help to alleviate this problem. These simplify the model-building process, quantify the goodness of fit of the model on a per-residue basis and locate possible errors in peptide and side-chain conformations.","journal":"Acta Crystallographica Section A Foundations of Crystallography","year":1991,"id":4412,"datarank":1.4168592974560246,"base_score":9.44572864970683,"endowment":9.44572864970683,"self_citation_contribution":1.4168592974560246,"citation_network_contribution":0.0,"self_endowment_contribution":1.4168592974560246,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":12653,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.0447,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"1991-03-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":45268,"name":"J.
