flybase 0.1.4

FlyBase sync/query helper for agents.

FlyBase local sync/query

Use FlyBase bulk files for agent workloads. Live API: helper only.

Why

• https://api.flybase.org/api/v1.0/ exists.
• some endpoints return useful JSON now, eg domain/FBgn0001250, sequence/id/FBgn0001250.
• some plausible endpoints return empty body today.
• bulk bucket + release files: better for repeatable agent queries.

Current surfaces checked

• release bucket: https://s3ftp.flybase.org/releases/current/
• precomputed files: https://s3ftp.flybase.org/releases/current/precomputed_files/
• Postgres dump: https://s3ftp.flybase.org/releases/current/psql/FB2026_01.sql.gz
• API root: https://api.flybase.org/api/v1.0/
• batch download: https://flybase.org/batchdownload

Layout

• src/flybase_cli/: package code
• tests/: stdlib unittest
• flybase_cli.py: thin repo-root shim
• pyproject.toml: package metadata / console entrypoint

Sync presets

• gene-core: summaries + FBgn/FBtr/FBpp + annotation IDs + SO annotations
• gene-expression: curated/high-throughput/scRNA expression slices
• references: publication/link tables
• gene-knowledge: core gene facts + representative publications + orthology tables
• orthology: ortholog, paralog, and disease-association tables
• interactions: gene- and allele-level interaction tables

Full sync

• full-sync crawls an entire release prefix, default precomputed_files/
• default behavior: download only files the current loaders can ingest into SQLite
• use --all-files if you want non-ingestable release artifacts too
• use --include / --exclude to stage a narrower smoke or partial warehouse
• default manifest path: data/flybase/manifests/<release>/full-sync.json

Discovery

• genomes --release FB2026_01 lists genome builds linked from that FlyBase release
• sync-url turns a crawlable FlyBase directory URL into a one-step local sync
• sync-genome resolves a release/build pair into the right genome-section URL automatically
• genome-presets lists reusable genome asset sync recipes

Genome sync

• sections: fasta, gff, gtf, dna, chado-xml
• asset shortcuts include mirna, transcript, translation, gene, chromosome, cds, ncrna, gff, gtf
• presets include mirna-fasta, transcript-fasta, translation-fasta, gene-fasta, chromosome-fasta, ncrna-fasta, gff-all, gtf-all
• use --include/--exclude for narrower file selection on top of the asset preset

Ingest formats

• delimited: tsv, csv, gzipped variants
• sequence: fasta, fa, fna, faa, gzipped variants
• annotation: gff, gff3, gtf, gzipped variants
• JSON: json, json.gz

JSON ingest

• top-level scalar JSON fields become queryable SQLite columns
• one nested dict level is flattened, eg gene.symbol -> gene_symbol
• repeated top-level lists become child tables, eg symbolSynonyms -> <table>_symbolsynonyms
• repeated lists nested inside child dict rows become descendant tables, eg genomeLocations[].exons[] -> <table>_genomelocations_exons
• full source record remains in payload_json

Example:

python3 flybase_cli.py sql \
  "select record_id, symbol, gene_geneId from fb_ncrna_genes_fb_2026_01 limit 5"

python3 flybase_cli.py sql \
  "select parent_record_id, ordinal, value \
   from fb_ncrna_genes_fb_2026_01_symbolsynonyms \
   limit 5"

python3 flybase_cli.py sql \
  "select parent_record_id, parent_ordinal, ordinal, startPosition, endPosition \
   from fb_ncrna_genes_fb_2026_01_genomelocations_exons \
   limit 5"

Search

• fts-build creates a local SQLite FTS5 index from ingested tables
• search queries that index without calling the live FlyBase API
• record ids prefer stable FlyBase-like columns such as fbgn_id, primary_fbgn, flybase_fbtr

Metadata

• describe summarizes ingested tables with row counts, source paths, semantic tags, columns, and representative non-empty values
• schema-export writes the same metadata to a deterministic JSON artifact beside the SQLite DB, eg FB2026_01.schema.json
• schema-export also includes inferred relationships for nested child tables and common FlyBase ID joins
• schema-export also emits semantic_summary for table/entity tag coverage
• schema-export also emits ready-to-run query_templates
• query-plan prints starter SQL without the larger schema payload
• query-plan now includes named biological templates such as gene-summary-by-fbgn, transcript-protein-links, publications-for-gene, and coordinate lookups when matching tables exist
• query-run selects one template and executes it with parameter values
• useful first step before writing ad hoc SQL or building agent query plans

Example:

python3 flybase_cli.py schema-export \
  --db data/flybase/FB2026_01.sqlite \
  --sample-values 1

python3 flybase_cli.py query-plan \
  --db data/flybase/FB2026_01.sqlite \
  --sample-values 1 \
  --limit 5

python3 flybase_cli.py query-run \
  --db data/flybase/FB2026_01.sqlite \
  --template-name gene-summary-by-fbgn \
  --param fbgn_id=FBgn0002121

Notes

• nested JSON child tables keep lineage columns like parent_record_id, parent_ordinal, ordinal.
• many FlyBase files start with ## metadata lines; loader skips those.
• sync writes a preset manifest under data/flybase/manifests/<release>/.
• full-sync is the broadest offline path for release bulk data without going through the full Postgres dump.
• sync --release FB2026_01 defaults to data/flybase/FB2026_01.sqlite to avoid cross-release mixing.
• sync-incremental uses stable manifest keys so release-renamed files still land in updated instead of noisy add/remove pairs.
• release-diff compares releases either by raw prefix or by curated multi-prefix preset.
• manifest --url lets you crawl non-releases/ FlyBase directories such as genome FASTA/GFF trees.
• sync-url is the shortest path for genome assets once you know the directory URL.
• sync-genome is the shortest path when you know the FlyBase release + genome build label.
• sync-genome --preset ... is the preferred path for common genome asset pulls.
• some FlyBase .gff.gz assets are tar-wrapped gzip archives; loader handles that transparently.
• sql and query-run shape results as record-oriented JSON with summary metadata for agent chaining.
• pg-load stages the full Postgres import script for releases/<release>/psql/<release>.sql.gz.
• pg-load --execute runs the staged script when createdb and psql are installed locally.
• SQLite keeps setup minimal; switch to DuckDB/Postgres if you want bigger joins/faster scans.
• if you only need a few IDs, FlyBase Batch Download may be simpler than syncing files.
• use --no-header for files whose first non-comment row is data, not column names.
