uniret 1.0.0

UniProt SNP variation retrieval and processing toolkit

UniRet

UniRet is a command-line toolkit for retrieving and processing UniProt SNP variation data via the EBI Proteins API.

---

Installation

git clone https://github.com/sushi-cpu/UniRet.git
cd UniRet
pip install -e .

After install, the uniret command is available globally.

---

Quick start

Run the full pipeline (fetch → parse → sort) in one command:

uniret run -i proteins.xlsx -o ./results

Output layout:

results/
├── json/               # raw variation JSONs from EBI
├── variations/         # parsed flat CSV/TSV/JSON tables
└── sorted/             # per-protein folders split by variation type
    └── P12345_variations/
        ├── Natural variant.csv
        ├── Mutagenesis.csv
        └── ...

---

Input formats

UniProt IDs can be supplied in any combination of:

Method	Example
Excel file	-i proteins.xlsx (needs a UniprotID column)
CSV / TSV	-i proteins.csv (same column requirement)
Plain text	-i ids.txt (one ID per line)
Inline args	uniret fetch snp P12345 Q8N158 -o ./out

---

Commands

uniret run — full pipeline

uniret run -i proteins.xlsx -o ./results
uniret run P12345 Q8N158    -o ./results -f tsv
uniret run -i ids.txt       -o ./results --skip-fetch   # re-use existing JSONs

---

uniret fetch snp — fetch variation data

uniret fetch snp -i proteins.xlsx -o ./data/json
uniret fetch snp P12345 Q8N158    -o ./data/json --delay 0.5

---

uniret fetch info — fetch general UniProt entries

uniret fetch info -i proteins.xlsx -o ./data/json
uniret fetch info P12345           -o ./data/json

---

uniret parse snp — parse variation JSONs

uniret parse snp -d ./data/json -o ./data/variations -f csv
uniret parse snp -d ./data/json -o ./data/variations -f tsv
uniret parse snp -d ./data/json -o ./data/variations -f json

---

uniret parse info — parse UniProt info JSONs

uniret parse info -d ./data/json -o ./data/info -f csv

---

uniret sort — split variations by type

uniret sort -d ./data/variations -o ./data/sorted -f csv

---
