{"doi":"10.1093/molbev/msw054","title":"MEGA7: Molecular Evolutionary Genetics Analysis Version 7.0 for Bigger Datasets","abstract":"We present the latest version of the Molecular Evolutionary Genetics Analysis (Mega) software, which contains many sophisticated methods and tools for phylogenomics and phylomedicine. In this major upgrade, Mega has been optimized for use on 64-bit computing systems for analyzing larger datasets. Researchers can now explore and analyze tens of thousands of sequences in Mega The new version also provides an advanced wizard for building timetrees and includes a new functionality to automatically predict gene duplication events in gene family trees. The 64-bit Mega is made available in two interfaces: graphical and command line. The graphical user interface (GUI) is a native Microsoft Windows application that can also be used on Mac OS X. The command line Mega is available as native applications for Windows, Linux, and Mac OS X. They are intended for use in high-throughput and scripted analysis. Both versions are available from www.megasoftware.net free of charge.","journal":"Molecular Biology and Evolution","year":2016,"id":3902,"datarank":1.6081129819398703,"base_score":10.720753212932467,"endowment":10.720753212932467,"self_citation_contribution":1.6081129819398703,"citation_network_contribution":0.0,"self_endowment_contribution":1.6081129819398703,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":45285,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.4243,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2016-03-22","fair_score":61.25,"fair_percentile":92.70008795074759,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":3956,"name":"Glen Stecher","orcid":null,"position":1,"is_corresponding":false},{"id":3955,"name":"Koichiro Tamura","orcid":"0000-0001-7189-5399","position":2,"is_corresponding":false},{"id":3959,"name":"Sudhir Kumar","orcid":"0000-0002-9918-8212","position":0,"is_corresponding":true}],"reference_count":12,"raw_metadata":{"citation_network_status":"fetched"},"created_at":"2026-03-01T18:20:47.508186Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":100.0,"fair_a":70.0,"fair_i":50.0,"fair_r":25.0,"fair_zscore":1.4508,"fair_rationale":{"fair_score":61.25,"has_llm":false,"dimensions":{"F":{"name":"Findable","score":100.0,"criteria":[{"key":"f_has_doi","label":"Has a persistent DOI","kind":"deterministic","weight":1.0,"fraction":1.0,"signal":"DOI present","rationale":null},{"key":"f_repository_presence","label":"Indexed in repositories / literature DBs","kind":"deterministic","weight":1.0,"fraction":1.0,"signal":"datacite=25, pmcid=True, pmid=True","rationale":null},{"key":"f_persistent_ids","label":"Resolvable scholarly identifiers (OpenAlex)","kind":"deterministic","weight":0.5,"fraction":1.0,"signal":"OpenAlex id present","rationale":null}]},"A":{"name":"Accessible","score":70.0,"criteria":[{"key":"a_open_access","label":"Open Access / files deposited","kind":"deterministic","weight":1.5,"fraction":0.5,"signal":"files/OA location present but not flagged OA","rationale":null},{"key":"a_retrievable","label":"Free full text retrievable","kind":"deterministic","weight":1.0,"fraction":1.0,"signal":"8 OA location(s)","rationale":null}]},"I":{"name":"Interoperable","score":50.0,"criteria":[{"key":"i_linked_data","label":"Linked datasets / DataCite relations","kind":"deterministic","weight":1.0,"fraction":1.0,"signal":"linked_datasets=25, datacite=25","rationale":null},{"key":"i_standard_ids","label":"References data via standard accessions","kind":"deterministic","weight":1.0,"fraction":0.0,"signal":"accessions=0, trials=0","rationale":null}]},"R":{"name":"Reusable","score":25.0,"criteria":[{"key":"r_license","label":"Clear, open reuse license","kind":"deterministic","weight":1.5,"fraction":0.5,"signal":"license present (https://academic.oup.com/journals/pages/open_access/funder_policies/chorus/standard_publication_model)","rationale":null},{"key":"r_downloads","label":"Demonstrated reuse (downloads)","kind":"deterministic","weight":0.5,"fraction":0.0,"signal":"downloads=0","rationale":null},{"key":"r_version","label":"Versioned / maintained","kind":"deterministic","weight":0.5,"fraction":0.0,"signal":"no version chain","rationale":null},{"key":"r_dataset","label":"Classified as a data resource","kind":"deterministic","weight":0.5,"fraction":0.0,"signal":"not a dataset","rationale":null}]}},"suggestions":["Reference data using standard accessions (e.g. GEO, PDB, ClinicalTrials.gov).","Maintain explicit versioning for the dataset.","Make the paper/data Open Access or deposit the files in an open repository.","Attach a clear, open reuse license (e.g. CC-BY or CC0)."],"model":null,"agent_version":"fair_agent_v1","fulltext_source":"abstract_only"},"fair_model":null,"fair_agent_version":"fair_agent_v1","fair_fulltext_source":"abstract_only","fair_has_llm":false,"fair_computed_at":"2026-06-10T18:51:44.715596Z","clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
