gget 是做什么的?

概述

gget 是一个命令行生物信息学工具和 Python 包,为 20 多个基因组数据库和分析方法提供统一访问接口。通过一致的接口查询基因信息、序列分析、蛋白质结构、病毒序列、表达数据、疾病关联以及小鼠组织/细胞特异性指标。大多数 gget 模块既可以作为命令行工具使用,也可以作为 Python 函数调用。

重要提示:gget 查询的数据库会不断更新,这有时会改变其结构。此处指南针对 gget 0.30.5(截至 2026-06-07 的 PyPI 当前版本)。对于可重复的工作,请固定 gget==0.30.5;对于上游数据库适配器损坏的情况,请在查看发行说明后更新 gget。

安装

在干净的虚拟环境中安装 gget 以避免冲突:

# 针对此技能的可重复安装
uv venv .venv
source .venv/bin/activate
uv pip install "gget==0.30.5"

# 在 Python/Jupyter 中
import gget

快速开始

所有模块的基本使用模式:

# 命令行
gget <module> [arguments] [options]

# Python
gget.module(arguments, options)

大多数模块返回:

  • 命令行:JSON(默认)或 CSV(使用 -csv 标志)
  • Python:DataFrame 或字典

各模块通用标志:

  • -o/--out:将结果保存到文件
  • -q/--quiet:隐藏进度信息
  • -csv:返回 CSV 格式(仅命令行)

Python 参数名称通常匹配长 CLI 选项,不包含前导连字符。例如,--census_version 变为 census_version=...。使用 gget <module> --help 获取精确的当前签名。

模块类别

gget 暴露了六个类别的 23 个模块。每个模块的参数、CLI 和 Python 示例以及返回形状均在 references/module_catalog.md 中;更详细的每个参数文档在 references/module_reference.md 中。

类别模块
1. 参考与基因信息ref(Ensembl 参考下载)、search(基因搜索)、info(基因/转录本详情)、seq(核苷酸和蛋白质序列)
2. 序列分析与比对blast、blat、muscle(多重比对)、diamond(局部比对)
3. 结构与蛋白质分析pdb(结构和元数据)、alphafold(结构预测)、elm(线性模体)
4. 表达与疾病数据archs4(相关性、组织表达)、cellxgene(单细胞)、enrichr(富集分析)、bgee(直系同源与表达)、opentargets(疾病与药物)、cbio(癌症基因组学)、cosmic(突变)
5. 病毒与小鼠特异性virus(病毒序列)、8cube(小鼠特异性和表达)
6. 附加工具mutate(突变序列)、gpt(文本生成)、setup(安装模块依赖项)

几个模块在首次使用前需要一次性运行 gget setup(alphafold、elm、cellxgene),并且 cosmic 会提示输入 COSMIC 凭据以下载其数据库。

常见工作流程

多模块流水线——基因特征描述、结构比较、表达和富集分析、疾病和药物关联、直系同源比较以及用于 kallisto 或比对参考文件的准备——在 references/common_workflows.md 中提供,更长的版本在 references/workflows.md 中。

最佳实践

数据检索

  • 对于大型查询,使用 --limit 控制结果大小
  • 使用 -o/--out 保存结果以确保可重复性
  • 检查数据库版本/发布以确保分析间的一致性
  • 在生产脚本中使用 --quiet 以减少输出

序列分析

  • 对于 BLAST/BLAT,从默认参数开始,然后调整灵敏度
  • 使用带有 --threads 参数的 gget diamond 以获得更快的局部比对
  • 为重复查询保存 DIAMOND 数据库,使用 --diamond_db
  • 对于多重序列比对,对大型数据集使用 -s5/--super5

表达与疾病数据

  • 基因符号在 cellxgene 中区分大小写(例如,'PAX7' 与 'Pax7')
  • 在首次使用 alphafold、cellxgene、elm、gpt 之前运行 gget setup
  • 对于富集分析,使用数据库快捷方式以方便操作
  • 使用 -dd 缓存 cBioPortal 数据以避免重复下载
  • 对于 OpenTargets,在编写筛选器之前检查返回的列名;gget 0.30.5 遵循更新的 OpenTargets API 模式

结构预测

  • AlphaFold 多聚体预测:使用 -mr 20 以获得更高的准确性
  • 使用 -r 标志对最终结构进行 AMBER 松弛
  • 在 Python 中使用 plot=True 可视化结果
  • 在运行 AlphaFold 预测之前,先检查 PDB 数据库

病毒数据

  • 在请求广泛病毒数据集之前,对 gget virus 使用限制性筛选器
  • 将 command_summary.txt 与下游结果一起保存,以确保在部分下载后可重复性和恢复
  • 使用 --baseline 和 --merge-results 恢复中断的病毒元数据/序列下载

错误处理

  • 数据库结构会发生变化;当适配器损坏时,请检查上游发行说明并显式固定更新的固定版本
  • 对于可重复的环境,固定已知良好的版本:uv pip install "gget==0.30.5"
  • 使用 gget info 一次处理最多约 1000 个 Ensembl ID
  • 对于大规模分析,实施 API 查询速率限制
  • 使用虚拟环境避免依赖冲突
  • 将 COSMIC 和 OpenAI 凭据保存在命名的环境变量或交互式提示中;不要将真实凭据写入示例、笔记本或日志中

输出格式

命令行

  • 默认:JSON
  • CSV:添加 -csv 标志
  • FASTA:gget seq、gget mutate
  • PDB:gget pdb、gget alphafold
  • PNG:gget cbio plot
  • FASTA/CSV/JSONL 文件夹:gget virus

Python

  • 默认:DataFrame 或字典
  • JSON:添加 json=True 参数
  • 保存到文件:添加 save=True 或指定 out="filename"
  • AnnData:gget cellxgene
  • DataFrame/JSON:gget 8cube specificity、psi_block、expression

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.
