Dataset Card for `neuralbioinfo/PhaStyle-SequenceDB`

phastyle Sequence Database

A collection of bacteriophage nucleotide sequences and metadata for training and evaluating phage lifestyle prediction models. Available splits support both strict-holdout and standard-holdout experiments.

Dataset Features

Name	Type	Description
`sequence_id`	`int64`	Unique integer identifier for each sequence
`dataset`	`string`	Source collection name (see “Splits” below)
`class_label`	`string`	Lifestyle label: `"temperate"` or `"virulent"`
`y`	`int64`	Binary label: `0` = temperate, `1` = virulent
`source_fasta_id`	`string`	Original FASTA record ID
`orientation`	`string`	Strand orientation: `"forward"` or `"reverse_complement"`
`test_fastaid`	`string`	FASTA ID used in the test split (if applicable)
`L_seq`	`int64`	Sequence length in base pairs
`source_description`	`string`	Free‐text description of isolate or environment
`Genome type`	`string`	“dsDNA”, “ssDNA”, etc.
`Family`	`string`	Taxonomic family
`subds_seqid`	`int64`	Sub‐dataset sequence index (internal use)
`sequence`	`string`	Nucleotide sequence

Splits

BACPHLIP_TRAINING (1,798 examples, 116 MB)
- Used for strict-holdout training (excludes any Escherichia-infecting phages or ≥ 80 % ANI to test set).
BACPHLIP_VALIDATION (316 examples, 25 MB)
- Escherichia phages held out for validation in the strict-holdout setting.
BACPHLIP_ALL (2,114 examples, 142 MB)
- Used for standard-holdout training (no ANI or host exclusions).
ESCHERICHIA (394 examples, 22 MB)
- Guelin collection: experimentally validated Escherichia phages.
BASEL (412 examples, 27 MB)
- BASEL collection: environmental E. coli isolates.
EXTREMOPHILE (16 examples, 0.8 MB)
- Phages from deep‐sea, acidic, and arsenic‐rich environments.

Dataset Creation

The sequences in this dataset were gathered from various sources, including the BACPHLIP database and curated collections of phages from extreme environments. Each sequence was carefully segmented into smaller fragments (512bp or 1022bp) to simulate real-world scenarios where phage sequences are often fragmented. The training data excludes Escherichia sequences, which are used in the test set to evaluate model generalization capabilities.

Intended Uses

This dataset is intended for use in phage lifestyle prediction tasks using genomic language models such as ProkBERT. The segmented sequences allow models to generalize well even with fragmented or out-of-sample data. It is particularly useful for applications in ecological and clinical settings where understanding phage behavior is critical.
