GAMBA ATG 5-Way

This dataset packages GAMBA's five-way ATG representation benchmark. GAMBA selects 2,000 complete MANE Select transcript examples approximately evenly across chr1–chr22; each example contributes five rows:

1. true translation start;
2. nearby noncoding ATG, 2–5 kb away;
3. far noncoding ATG, at least 100 kb away;
4. same-transcript in-frame methionine;
5. same-transcript out-of-frame ATG motif.

The five rows share a pair_id, yielding 10,000 rows total.

Columns

Column	Description
split, label, label_id	Always test and one of the five ATG classes.
sequence	Strand-oriented GAMBA context of at most 2,048 bp.
pair_id	Shared identifier for all five sites from one transcript example.
category, scope	Constant ATG category and ROI pooling scope.
chrom, start, end, strand	Zero-based, half-open hg38 three-base site coordinates.
context_start, context_end	Forward-genome coordinates of sequence.
roi_start, roi_end, pool_start, pool_end	ATG offsets within the context.
name, transcript_id, gene_id	Site and source transcript identifiers.
delta_bp	Signed distance from the true start; zero for label 1.
phylop_mean, phylop_std	Mean and population standard deviation over the three-base ATG.
phylop_frac_pos, phylop_frac_neg	Fractions of ATG bases with positive or negative phyloP scores.
phylop_mean_pos, phylop_mean_neg	Means over positive or negative ATG scores, or zero when absent.
phylop_context_mean, phylop_context_std	Mean and population standard deviation over GAMBA's symmetric 2,048 bp phyloP context.
phylop_context_frac_pos, phylop_context_frac_neg	Fractions of context bases with positive or negative scores.
phylop_context_mean_pos, phylop_context_mean_neg	Means over positive or negative context scores, or zero when absent.

Data source and processing

The chromosome-level source TSVs, combined TSV, and sampled 2,000 examples produced by Gamba-Processing match Microsoft GAMBA commit e83984e byte-for-byte.

GAMBA stores minus-strand ATG sites as [position, position + 3) before reverse complementation. This release preserves that convention exactly.

PhyloP values come from the Zoonomia 241-mammalian track used by GAMBA. Uncovered positions are zero and scores are rounded to two decimal places before the float32 summaries are computed.
