pridepy 0.0.13

Python Client library for PRIDE Rest API

pridepy

pridepy is a Python client and CLI for the PRIDE Archive API.

You can:

• download public and private PRIDE files
• download by category (RAW, SEARCH, RESULT, etc.)
• stream project and file metadata
• search projects by keyword and filters
• download raw files from ProteomeXchange XML metadata

The downloader supports ftp, aspera, s3, and globus.
By default it starts with FTP, falls back across the remaining protocols when needed, and validates downloaded files (non-empty, and checksum validation when enabled).

Requirements

• Python >=3.9

Installation

Option 1: Install from PyPI with uv (recommended)

Install as a CLI tool:

uv tool install pridepy
pridepy --help

Or run without installing globally:

uvx pridepy --help

Option 2: Install from PyPI with pip

pip install --upgrade pridepy
pridepy --help

Option 3: Install from source (development)

git clone https://github.com/PRIDE-Archive/pridepy
cd pridepy
uv sync --extra dev
uv run pridepy --help

Quick Start (New Users)

1) Download all raw files for a project (robust mode)

pridepy download-all-public-raw-files \
  -a PXD008644 \
  -o ./downloads/PXD008644 \
  --checksum-check

What this does:

• default ftp starts with FTP and falls back (ftp -> aspera -> s3 -> globus)
• --checksum-check downloads project checksums and validates files
• empty/corrupt files are retried automatically

2) Continue interrupted downloads safely

pridepy download-all-public-raw-files \
  -a PXD008644 \
  -o ./downloads/PXD008644 \
  --skip-if-downloaded-already \
  --checksum-check

3) Download only selected categories

pridepy download-all-public-category-files \
  -a PXD022105 \
  -o ./downloads/PXD022105 \
  -c RAW,SEARCH

4) Download one file by name

pridepy download-file-by-name \
  -a PXD022105 \
  -f checksum.txt \
  -o ./downloads/PXD022105 \
  --checksum-check

5) Download raw files from ProteomeXchange

pridepy download-px-raw-files \
  -a PXD039236 \
  -o ./downloads/PXD039236

from pridepy.project.project import Project

project = Project()
results = project.search_by_keywords_and_filters(
    keyword="PXD009476",
    query_filter="",
    page_size=25,
    page=0,
    sort_direction="DESC",
