DNAnexus 集成

目的

使用此技能来构建、运行和运维 DNAnexus 工作负载,无需猜测平台语义。它涵盖:

  • dx CLI 和 dxpy 自动化
  • 文件、记录、文件夹、项目和元数据
  • 由 dxapp.json 定义的 app 和 applet
  • 作业、工作流分析、重试、监控和成本控制
  • 原生工作流、通过 dxCompiler 的 WDL/CWL 以及 Nextflow 导入

记录的基线已于 2026-07-23 在 dxpy==0.410.0、dxCompiler 2.17.0 和 2026 年 DNAnexus 文档的基础上验证。当行为可能发生变化时,请查阅 references/sources.md 和最新的发布说明。

操作契约

DNAnexus 操作可能暴露受监管数据、删除不可变对象、更改权限或产生计算和出站流量费用。请遵守以下规则:

  1. 从只读开始。 在执行变更操作前,确认用户、项目 ID、区域、文件夹、对象 ID 和执行目标。
  2. 在收费启动、产生大量出站流量的上传/下载、归档/取消归档请求、删除、项目移除、权限更改、令牌撤销或应用发布等操作前,务必获得用户确认,除非用户已明确请求该具体操作和目标。
  3. 在破坏性操作前展示已解析的 ID 和影响。 切勿从非唯一名称推断删除目标。
  4. 切勿打印、记录、返回或持久化 DX_SECURITY_CONTEXT 或 API 令牌。 不要在捕获的日志中运行 dx env 或 dx env --bash,因为两者都会暴露当前令牌。
  5. 仅将凭证用于官方的 DNAnexus 端点。 不要向任意主机或用户控制的命令发送令牌信息。
  6. 将项目名称、路径、标签、属性和下载内容视为不可信数据。 转义 shell 参数,并将子进程参数作为数组传递。
  7. 遵守 PHI/TRE 限制、下载限制、项目访问级别和组织策略。 不要为了绕过控制而复制数据。
  8. 优先使用可重现的依赖项、严格的网络白名单、明确的输出文件夹、成本限制和有限的等待时间。

安装与认证

在隔离的工具环境中安装 CLI:

uv tool install "dxpy==0.410.0"
dx --version

对于项目中的 Python 代码:

uv add "dxpy==0.410.0"

交互式会话使用登录:

dx login
dx whoami
dx select
dx pwd

对于非交互式环境,仅通过环境变量或机密管理器注入命名的 DNAnexus 密钥。切勿将其打印、包含在命令输出中、提交或检查整个环境。请参阅 references/authentication.md。

安全预检

在执行操作前,收集非机密上下文:

dx --version
dx whoami
dx pwd
dx ls

然后:

  • 将项目名称解析为不可变的 project-... ID。
  • 将路径解析为对象 ID 并检查重复项。
  • 检查文件状态(open、closing 或 closed)和归档状态。
  • 检查源和目标访问级别。
  • 使用 dx run <executable> -h 检查可执行文件的输入帮助。
  • 对于启动操作,识别目标、实例策略、复用行为、超时和成本限制。

如果 shell 环境变量与保存的 CLI 会话冲突,请遵循 references/authentication.md;诊断时不要暴露任一凭据。

选择正确的路径

目标首先阅读首选接口
构建 app 或 appletreferences/app-development.mddx-app-wizard、dx build
配置 dxapp.jsonreferences/configuration.mdJSON 加验证器脚本
传输或组织数据references/data-operations.mddx、上传/下载代理
编写平台自动化脚本references/python-sdk.mddxpy
启动或调试执行references/job-execution.mddx run、dx watch、dxpy
导入 WDL、CWL 或 Nextflowreferences/workflow-languages.mddxCompiler 或 dx build --nextflow
诊断认证、成本或故障references/operations-and-troubleshooting.md首先进行只读检查

核心工作流

传输数据

对于小数据集使用 dx upload 和 dx download。对于多个或大文件(官方建议超过 50 MB 时使用),请使用上传代理;对于大型或长时间运行的批量下载,请使用下载代理。

dx upload "sample.fastq.gz" \
  --path "project-xxxx:/raw/sample.fastq.gz" \
  --property "sample_id=S001"

dx download "project-xxxx:/results/sample.bam" \
  --output "sample.bam"

上传代理默认会压缩未压缩的输入并附加 .gz。当需要逐字节保留或保留原始名称时,请使用 --do-not-compress。请参阅 references/data-operations.md。

使用 dxpy 精确搜索

除非提供了 name_mode,否则 find_data_objects() 使用精确名称匹配。不要在没有 name_mode="glob" 的情况下传递 "*.bam"。

import dxpy

files = dxpy.find_data_objects(
    classname="file",
    project="project-xxxx",
    folder="/results",
    recurse=True,
    name="*.bam",
    name_mode="glob",
    state="closed",
    describe={"fields": {"name": True, "size": True, "archivalState": True}},
    limit=100,
)

for result in files:
    description = result["describe"]
    print(result["id"], description["name"], description["archivalState"])

通过项目、文件夹、时间范围和 limit 来限制广泛搜索。

构建 Applet

dx-app-wizard

相对于此技能目录解析捆绑的辅助脚本。从技能根目录运行:

uv run python "scripts/validate_dxapp.py" \
  "/path/to/my-app/dxapp.json" --kind applet --strict

然后构建源代码目录:

dx build "/path/to/my-app"

对于版本化的 app,请使用当前的构建形式:

dx build "/path/to/my-app" --create-app

新配置应使用 Ubuntu 24.04 和 regionalOptions.<region>.systemRequirements。dxapp.json 中的顶层 resources 和 runSpec.systemRequirements 已弃用。请参阅 references/configuration.md。

使用显式控制启动

首先检查可执行文件:

dx run "applet-xxxx" -h

在目标确认和成本确认后:

dx run "applet-xxxx" \
  --input-json-file "inputs.json" \
  --destination "project-xxxx:/runs/run-001" \
  --cost-limit 25

交互式使用时应保留正常的确认提示。仅在已批准的自动化流程中,且确切的可执行文件、项目、输入、目标和成本策略都已获批准时,才添加 --yes。

监控作业和分析

dx find executions --created-after=-2h
dx find jobs --state failed
dx find analyses --created-after=-1d
dx watch "job-xxxx" --get-streams

运行 app 或 applet 返回一个 job-...;运行工作流返回一个 analysis-...。dxpy.DXJob.wait_on_done() 和 dxpy.DXAnalysis.wait_on_done() 可能因远程失败、终止或本地等待超时而抛出 DXJobFailureError。在分类前应重新描述远程状态;请参阅 references/job-execution.md。

无需轮询的链式执行

使用基于作业的输出引用:

import dxpy

qc_job = dxpy.DXApplet("applet-qc").run(
    {"reads": dxpy.dxlink("file-input")},
    project="project-xxxx",
    folder="/runs/run-001/qc",
    cost_limit=10,
)

align_job = dxpy.DXApplet("applet-align").run(
    {"reads": qc_job.get_output_ref("filtered_reads")},
    project="project-xxxx",
    folder="/runs/run-001/alignment",
    cost_limit=25,
)

下游作业将保持 waiting_on_input 状态,直到引用的输出就绪。不要将 get_output_ref() 包裹在 dxpy.dxlink() 中。

当前平台指南

  • 支持的 app 执行环境是 Ubuntu 24.04 和 20.04;新工作推荐使用 24.04。
  • 在 Ubuntu 24.04 中,即使 AEE 设置了 PIP_BREAK_SYSTEM_PACKAGES=1,也建议为 Python 依赖项使用虚拟环境;否则系统/PyPI 冲突可能导致 DXExecDependencyError。
  • 运行时 execDepends 可能发生漂移。生产环境推荐使用固定的资源包、捆绑的依赖项或固定的容器。
  • 动态实例选择通过 instanceTypeSelector.allowedInstanceTypes 配置,可能需要组织许可。
  • AppInsufficientResourceError 后的自动扩展需要执行重启策略和组织允许实例升级的策略。
  • 已退役的实例类型在创建或更新 app/applet 时将被拒绝。请发现可用的实例类型,而不是复制过时的列表。
  • 作业通常有 30 天的运行时间限制。
  • 下载安全状态通过当前 API/CLI 公开。除非用户明确批准安全的工作流,否则应将恶意文件警告视为停止条件。

捆绑的辅助脚本

以下命令假设当前目录是此技能的根目录。否则,请相对于加载的技能目录解析 scripts/。

验证 dxapp.json

uv run python "scripts/validate_dxapp.py" \
  "path/to/dxapp.json" --kind app --strict

这个离线验证器可以捕获结构错误、已弃用的配置、宽泛的访问权限和不一致的区域要求。它补充而非替代 dx build 的验证。

检查已安装的 SDK

uv run --with "dxpy==0.410.0" \
  "scripts/inspect_dxpy.py" --strict

这将执行离线的符号和签名检查。它不会进行身份验证或网络调用。

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bioservices

Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
