pysec2pri 0.0.4

Secondary to primary identifier mapping

pySec2Pri

Create and use mapping files for secondary (retired/withdrawn) biological database identifiers and symbols to primary (current) identifiers and symbols.

Outputs mappings in SSSOM format by default. Subjects are secondary, objects are primary.

Installation

uv pip install pysec2pri

Or install from source:

uv pip install git+https://github.com/jmillanacosta/pysec2pri.git

Quick Start

Generating mapping sets

To obtain the secondary to primary identifier SSSOM mapping set for ChEBI:

pysec2pri chebi

This will automatically download the latest ChEBI release and generate an SSSOM mapping file in your current directory.

To process locally and specify the output:

pysec2pri chebi ChEBI_complete_3star.sdf --output my_mappings.sssom.tsv

For more options and help on any command:

pysec2pri --help
pysec2pri chebi --help

The default output is in SSSOM (Simple Standard for Sharing Ontology Mappings) TSV format.

Updating IDs and symbols

A generated mapping set can be used to update IDs and symbols in Python:

from pysec2pri import generate_chebi_synonyms, resolve_symbols
cs = generate_chebi_synonyms()
resolve_symbols(["Glucose", "ATP", "Guanine"], cs)

Or from the command line, given a TSV file gene_ex.tsv:

gene	data
HGNC:131	3.5

Resolve the gene column to primary HGNC IDs (a new _primary column is added):

pysec2pri update-ids gene_ex.tsv hgnc --at gene -o gene_ex_primary.tsv
# gene        data    gene_primary
# HGNC:131    3.5     HGNC:145

The same pattern works for symbols with update-symbols, and multiple columns can be resolved by repeating --at:

pysec2pri update-ids data.tsv hgnc --at gene_id --at related_gene_id

To skip regenerating the mapping set, pass a pre-built mapping file:

pysec2pri hgnc ids  # outputs hgnc_{version}_sssom.tsv
pysec2pri update-ids gene_ex.tsv hgnc --at gene --mapping hgnc_{version}_sssom.tsv
