This table lists every active species in the database that has a valid NCBI assembly accession: RefSeq (GCF_) — same as the green checkmark entries on NCBI — and GenBank (GCA_). The ACCESSION column shows which type each row uses. Column GENOME FILES lists only files that actually exist: each NCBI HTTPS link is checked with HEAD (results cached in instance/ncbi_genome_url_head_cache.json). Run 预热Download基因组缓存.bat to warm both caches so the first browser visit stays fast. Set env SKIP_VERIFY_GENOME_URLS=1 to skip HEAD checks (shows all four URLs again, not recommended). If NCBI cannot resolve the FTP folder but matching *.gz files exist under instance/ncbi_refseq_genomes/ (names starting with the assembly accession), only those files appear as local download links. Optional Local FASTA if you place a file under app/static/genomes/. RESOURCES includes the NCBI Datasets ZIP and portals. Resolved FTP folder names are saved under instance/ncbi_assembly_ftp_folder_cache.json so repeat visits are faster; run 预热Download基因组缓存.bat to warm the cache without opening the browser. To copy standard .gz files onto disk: 下载RefSeq基因组到文件夹.bat (RefSeq only) or 下载全部物种基因组到文件夹.bat (RefSeq + GenBank); default folder instance/ncbi_refseq_genomes/. Note: links in GENOME FILES download over HTTP (or open NCBI); they do not open Windows File Explorer. Use the per-row local folder path below that column — copy it into Explorer’s address bar to jump to the files on disk.
