Project description

Lims2 SDK

Version Python

生信云平台 Python SDK,提供图表上传和文件存储功能。

当前版本: v0.4.0

功能特性

  • 图表服务:支持 Plotly、Cytoscape、图片、PDF 格式上传
  • 文件存储:通过 STS 凭证上传文件到阿里云 OSS,支持断点续传
  • 命令行工具:提供便捷的 CLI 命令
  • 精度控制:使用 decimal 库精确四舍五入,默认保留3位小数,减少 JSON 文件大小(可减少 15-60%)

安装配置

推荐方式:从 PyPI 安装

pip install lims2-sdk

设置环境变量:

export LIMS2_API_URL="your-api"
export LIMS2_API_TOKEN="your-api-token"

命令行使用

** 详细参数说明使用 --help 查询 **

图表上传

# 上传图表文件(完整参数示例)
lims2 chart upload plot.json -p proj_001 -n "基因表达分析" -s sample_001 -t heatmap -d "差异表达热图" -c A_vs_B -a Expression_statistics --precision 3

文件存储

# 上传单个文件(完整参数示例)
lims2 storage upload results.csv -p proj_001 -a Expression_statistics -c results -s sample_001 -d "差异表达结果"

# 上传目录
lims2 storage upload-dir output/ -p proj_001 -a qc_analysis -c results -s sample_001

Python SDK 使用

from lims2 import Lims2Client

# 初始化客户端
client = Lims2Client()

# 上传图表(完整参数示例)
client.chart.upload(
    data_source="plot.json",        # 图表数据源:字典、文件路径或 Path 对象
    project_id="proj_001",          # 项目 ID(必需)
    chart_name="基因表达分析",        # 图表名称(必需)
    sample_id="sample_001",         # 样本 ID(可选)
    chart_type="heatmap",           # 图表类型(可选)
    description="差异表达基因热图",   # 图表描述(可选)
    contrast="A_vs_B",              # 对比策略(可选)
    analysis_node="Expression_statistics",  # 分析节点名称(可选)
    precision=3                     # 浮点数精度:0-10位小数(默认3)
)

# 上传文件(完整参数示例)
client.storage.upload_file(
    file_path="results.csv",        # 文件路径(必需)
    project_id="proj_001",          # 项目 ID(必需)
    analysis_node="Expression_statistics",  # 分析节点名称(必需)
    file_category="results",        # 文件分类(必需)
    sample_id="sample_001",         # 样本 ID(可选)
    description="差异表达结果文件",   # 文件描述(可选)
    progress_callback=lambda consumed, total: print(f"进度: {consumed/total*100:.1f}%")  # 进度回调函数(可选)
)

# 上传目录
client.storage.upload_directory(
    dir_path="output/",              # 目录路径(必需)
    project_id="proj_001",          # 项目 ID(必需)
    analysis_node="qc_analysis",    # 分析节点名称(必需)
    file_category="results",        # 文件分类(必需)
    sample_id="sample_001",         # 样本 ID(可选)
    recursive=True                  # 是否递归上传子目录(默认 True)
)
