Use Geniml for audited local genomic-interval workflows: validate BED and universe contracts, plan Region2Vec or scEmbed runs, inspect model/tokenizer compatibility, and assess consensus universes.

Geniml Use Geniml for machine learning and statistical workflows over genomic interval sets. Treat coordinates, assemblies, token vocabularies, model artifacts, and sample grouping as explicit contracts. The bundled scripts validate or plan; they do not import Geniml, contact services, deserialize models, or execute training. Bash is declared only for explicit, user approved uv , Python, Geniml, Gtars, Git, and native CLI commands shown in this guide; bundled Python helpers do not spawn subprocesses. Example paths under data/ , refs/ , work/ , and models/ are user provided project placeholders, not missing bundled files. Verified release snapshot Latest stable PyPI release on 2026 07 23: geniml==0.8.4 (2026 01 14). PyPI does not declare Requires Python ; its classifiers list Python 3.10 3.14. Prefer Python 3.11 or 3.12 where all native/ML wheels resolve. geniml==0.8.4 accepts gtars =0.2.5 ; the verified base smoke used current gtars==0.9.2 (2026 06 17, Python =3.10). Extras are ml and test . The base install omits Torch, Gensim, Scanpy, Hugging Face Hub, pyBigWig, and HMM dependencies. Upstream documentation contains stale examples. Release source and installed help output take precedence where they conflict. Install reproducibly Use a project environment and commit its generated lockfile: For Region2Vec, scEmbed, evaluation, or universe methods needing ML libraries: For a durable project, prefer: Do not install an unpinned Git branch. Record Python, OS/architecture, the resolved lockfile, and the PyPI artifact digest. Geniml itself is BSD 2 Clause; the MIT frontmatter value licenses this skill's content. Start with the safety gate Before importing Geniml or running an external binary: 1. Work only with explicit local regular files. Reject URLs, FIFOs, devices, and symlinks unless the user deliberately changes that policy. 2. Validate BED structure and the declared assembly against a trusted local chromosome sizes file. 3. Bound file count, bytes, rows, workers, epochs, and output size. 4. Separate train/validation/test by patient, donor, biological replicate, or other independent unit—not by BED row or cell alone. 5. Inventory and checksum the universe, tokenizer, model, config, inputs, metadata manifest, and native binaries. 6. Obtain explicit approval before any BEDbase or Hugging Face download. Never infer approval from a model ID or BEDbase identifier. 7. Keep logs aggregate and bounded. BED filenames, sample IDs, phenotypes, labels, barcodes, and genomic intervals may be sensitive. Coordinate and assembly contract BED intervals are normally 0 based, half open [start, end) : start is included, end is excluded, and length is end start . Do not mix them with 1 based closed coordinates from VCF/GFF or user facing genome browsers. For every corpus and artifact, record: assembly and patch/accession where possible (for example GRCh38 versus GRCh38.p14), plus the chromosome sizes checksum; contig naming convention ( chr1 versus 1 ), alt/random/decoy policy, and mitochondrial naming; coordinate convention, sorting order, duplicate/overlap policy, and whether BED strand is meaningful; liftover tool, chain digest, source/target assemblies, unmapped fraction, and post liftover validation. Reject negative coordinates, end <= start , integer overflow, unknown contigs, ends beyond contig length, malformed columns, mixed assemblies, and silent contig renaming. Sorting and normalization never repair an assembly mismatch. BED3 has no strand; when column 6 is present, preserve + , , or . unless the assay contract says otherwise. Run a bounded validation and normalization plan before analysis: The validator reports proposed actions but never rewrites the BED file. Current API map Region and tokenizer I/O Prefer Gtars for new interval/tokenizer code: RegionSet and Tokenizer also accept remote inputs in some constructors; this skill permits local paths only unless network access is explicitly approved. geniml.io.RegionSet(regions, backed=False) remains available as a legacy Python implementation; backed sets are iterable but not indexable. geniml.io.Region uses stop , while gtars.models.Region uses end . With gtars 0.9.2, seven special tokens are added to a BED vocabulary. Therefore len(tokenizer) is not simply the number of universe rows. Preserve universe row order and the exact special token map. Region2Vec The modern class lives at a concrete module path: The Parquet input must contain one list valued tokens column, one document per row. See [references/region2vec.md](references/region2vec.md) for export, encoding, legacy CLI, and evaluation details. scEmbed Import ScEmbed from geniml.scembed.main . AnnData .var must contain chr , start , and end ; rows are cells and nonzero features identify accessible regions. Pre tokenize to a Parquet tokens column and use the same Tokenizer for training and inference. See [references/scembed.md](references/scembed.md). BEDspace BEDspace remains in 0.8.4 and invokes an external StarSpace executable. StarSpace is archived and upstream Geniml does not pin a compatible revision. Treat BEDspace as a legacy reproduction path, not the default for new systems. See [references/bedspace.md](references/bedspace.md) for the exact stable CLI spelling and an immutable, explicitly unverified build baseline. Consensus universes and assessment The installed 0.8.4 CLI uses: CC/CCF/ML/HMM consume precomputed coverage bigWigs. Do not concatenate or generate coverage until all BED files pass the same assembly contract. Assessment and embedding metrics are distinct: assess universe measures fit of a universe to interval collections, while eval implements CTT, RCT, GDST, and NPT for embeddings. See [references/consensus peaks.md](references/consensus peaks.md) and [references/utilities.md](references/utilities.md). Important 0.8.4 migration notes The 0.7.0 changelog moved new RegionSet/tokenizer work toward Gtars. The 0.4.0 names TreeTokenizer and AnnDataTokenizer are historical; the current Gtars API exposes Tokenizer . In the 0.8.4 wheel, geniml.region2vec and geniml.scembed do not re export their modern classes/functions. Use the concrete module paths above. geniml tokenize and geniml region2vec call names no longer exported by their package init files; do not build new workflows around those CLI paths without an installed version smoke test. geniml scembed parses legacy MatrixMarket options but its command body is a no op in 0.8.4. Use geniml.scembed.main.ScEmbed . Official pages still show geniml assess ; the release command is geniml assess universe . .gtok remains present in legacy datasets, but upstream issue 14 proposes deprecating many file .gtok workflows. Prefer one bounded Parquet corpus. Config key embedding size is accepted only for backward compatibility; use embedding dim . Model and universe compatibility A Region2Vec/scEmbed inference bundle is valid only when these agree: model config.yaml vocab size and embedding dim ; exact universe.bed bytes/order and assembly; tokenizer implementation/version and special token IDs; checkpoint tensor shapes and pooling policy; Geniml/Gtars versions and any tokenization parameters. Geniml 0.8.4 defaults to checkpoint.pt , config.yaml , and universe.bed . Its loader uses torch.load(..., weights only=True) , but .pt , Gensim .model , pickle, joblib, and native binaries remain untrusted inputs. Inspect and checksum artifacts before loading; use an isolated environment and never load a checkpoint merely to discover its metadata. Region2VecExModel(model path="org/repo") , ScEmbed(model path="org/repo") , and Gtars Tokenizer.from pretrained(...) can download from Hugging Face. Local from pretrained("models/local") loads a local bundle. Pin Hub revision and expected hashes when a user approves download; then work offline from the verified cache. BEDbase downloads and caches BBClient.load bed , load bedset , and token cache operations may contact https://api.bedbase.org . The default cache is $BBCLIENT CACHE or ~/.bbcache ; BEDBASE API changes the endpoint. Do not read unrelated environment variables. Set an explicit project cache, estimate size, approve identifiers/endpoints, and verify returned checksums before use. Local inspection commands are safer: The cache bed , cache bedset , and cache tokens subcommands may use the network. Do not run them implicitly or include sensitive local BED files in an upload/cache workflow. Local audit and planning CLIs All scripts are standard library only and default to redacted JSON: Use help for resource limits and explicit path disclosure controls.
