DNAnexus Integration

Overview

DNAnexus is a cloud platform for biomedical data analysis and genomics. Build and deploy apps/applets, manage data objects, run workflows, and use the dxpy Python SDK for genomics pipeline development and execution.

When to Use This Skill

This skill should be used when:

• Creating, building, or modifying DNAnexus apps/applets
• Uploading, downloading, searching, or organizing files and records
• Running analyses, monitoring jobs, creating workflows
• Writing scripts using dxpy to interact with the platform
• Setting up dxapp.json, managing dependencies, using Docker
• Processing FASTQ, BAM, VCF, or other bioinformatics files
• Managing projects, permissions, or platform resources

Core Capabilities

The skill is organized into five main areas, each with detailed reference documentation:

1. App Development

Purpose: Create executable programs (apps/applets) that run on the DNAnexus platform.

Key Operations:

• Generate app skeleton with dx-app-wizard
• Write Python or Bash apps with proper entry points
• Handle input/output data objects
• Deploy with dx build or dx build --app
• Test apps on the platform

Common Use Cases:

• Bioinformatics pipelines (alignment, variant calling)
• Data processing workflows
• Quality control and filtering
• Format conversion tools

Reference: See references/app-development.md for:

• Complete app structure and patterns
• Python entry point decorators
• Input/output handling with dxpy
• Development best practices
• Common issues and solutions

2. Data Operations

Purpose: Manage files, records, and other data objects on the platform.

Key Operations:

• Upload/download files with dxpy.upload_local_file() and dxpy.download_dxfile()
• Create and manage records with metadata
• Search for data objects by name, properties, or type
• Clone data between projects
• Manage project folders and permissions
