🛡️ Robust PRIDE Client

Bullet-proof, dead-simple downloads from the PRIDE proteomics database

🎯 The Problem

Downloading mass spectrometry data from PRIDE is frustrating:

• ❌ Network timeouts and server errors
• ❌ Corrupted downloads without verification
• ❌ Complex setup and configuration
• ❌ No automatic retry or recovery
• ❌ Manual monitoring and error handling

🚀 The Solution

# One command to rule them all
pride-download PXD018033 --pairs --count 6

That's it. The system handles everything automatically:

• ✅ Auto-recovery from network failures and server errors
• ✅ Protocol fallback (Globus → Aspera → FTP)
• ✅ Checksum verification and automatic re-download
• ✅ Smart resource management adapts to your system
• ✅ Progress tracking with real-time updates
• ✅ Zero configuration with intelligent defaults

🔧 Installation

# One-command setup (recommended)
curl -sSL https://raw.githubusercontent.com/webwebb56/robust-pride-client/main/install.sh | bash

# Or with pip
pip install robust-pride-client

# Or from source
git clone https://github.com/your-username/robust-pride-client.git
cd robust-pride-client
pip install -e .

📖 Quick Start

Command Line

# Download entire dataset
pride-download PXD018033

# Download specific file types  
pride-download PXD018033 --patterns "*.wiff" "*.raw"

# Download matching file pairs (e.g., .wiff + .wiff.scan)
pride-download PXD018033 --pairs --count 6

# Preview dataset before downloading
pride-download PXD018033 --preview

# Search and download
pride-download "cancer proteomics 2023" --limit 5

Python API

from pride_client import RobustPrideClient

# One-line download
client = RobustPrideClient()
result = client.download_dataset("PXD018033")

# Download file pairs
result = client.download_file_pairs(
    "PXD018033", 
    [(".wiff", ".wiff.scan")], 
    count=6
)

# Preview before download
info = client.preview_dataset("PXD018033")
print(f"Files: {info['total_files']}, Size: {info['total_size_gb']}GB")

⚙️ Configuration

Performance Profiles

pride-config set-profile fast        # Maximum speed
pride-config set-profile balanced    # Good balance (default)
pride-config set-profile conservative # Slow but stable  
pride-config set-profile academic    # Optimized for institutions

Environment Variables

export PRIDE_DOWNLOAD_DIR="$HOME/Data/MS-Files"
export PRIDE_MAX_CONCURRENT=8
export PRIDE_PROFILE=fast

Config File (~/.pride/config.json)

{
  "profile": "balanced",
  "download_dir": "$HOME/Downloads/PRIDE",
  "max_concurrent": 4,
  "protocols": ["globus", "aspera", "ftp"],
  "verify_checksums": true
}

🛡️ Bullet-Proof Features

Automatic Recovery

• Network timeouts → Retry with exponential backoff
• Server errors → Try different protocol automatically
• Corrupted files → Verify checksums and re-download
• Process crashes → Auto-restart with state recovery
• Rate limiting → Intelligent backoff and queuing

Smart Resource Management

• Disk space → Pre-flight checks and graceful abort
• System load → Adapts concurrency to available resources
• Bandwidth → Optional throttling and optimization
• Memory usage → Efficient streaming and cleanup

Intelligent Discovery

# Smart file pattern matching
client.download_dataset("PXD018033", patterns=["*QC*", "*DIA*"])

# Automatic pair detection
pairs = client.find_file_pairs("PXD018033", [(".wiff", ".wiff.scan")])

# Preview with detailed analysis
info = client.preview_dataset("PXD018033")
# Shows file types, sizes, estimated download time

📊 Real-World Examples

Jupyter Notebook

import pride_client

# Download and immediately analyze
client = pride_client.RobustPrideClient()
result = client.download_dataset("PXD018033", patterns=["*.raw"])

if result["status"] == "success":
    files = list(Path(result["download_dir"]).glob("*.raw"))
    # Your analysis pipeline here...

Snakemake Pipeline

rule download_pride_data:
    output: "data/{dataset}/files.done"
    shell: "pride-download {wildcards.dataset} --output data/{wildcards.dataset}"

High-Throughput Laboratory

from pride_client import RobustPrideClient, ClientConfig

# Configure for maximum throughput
config = ClientConfig(
    max_concurrent=16,
    protocols=["aspera", "globus"], 
    bandwidth_limit_mbps=None
)

client = RobustPrideClient(config)

# Process multiple datasets  
datasets = ["PXD018033", "PXD019854", "PXD021013"]
for dataset_id in datasets:
    result = client.download_dataset(dataset_id)
    if result["status"] == "success":
        trigger_analysis_pipeline(result["download_dir"])

🔄 Migration from Existing Code

Before (with pridepy)

import subprocess
import time
import os

def download_with_retries(dataset_id):
    for attempt in range(3):
        try:
            cmd = ["pridepy", "download-all-public-raw-files", 
                   "-a", dataset_id, "-p", "globus"]
            subprocess.run(cmd, check=True)
            return True
        except subprocess.CalledProcessError:
            time.sleep(60)  # Wait and retry
    return False

# Manual error handling, monitoring, cleanup...

After (with robust-pride-client)

from pride_client import RobustPrideClient

client = RobustPrideClient()
result = client.download_dataset(dataset_id)  # Just works!
