# 安装指南

## 1. 系统配置最低要求

SDAS分析软件包在Linux系统上被解压和安装，计算环境需满足下列最低要求（无法支持部分分析（如cell2locationGPU模式））：

* 8-core Intel or AMD processor (>24 cores recommended)
* 128GB RAM (>256GB recommended)
* 200G free disk space or higher
* 64-bit CentOS/RedHat 7.8 or Ubuntu 20.04

## 2. 软件下载

WPS网盘：<https://365.kdocs.cn/l/ck8Q456MSkbq>&#x20;

Github: `git clone https://github.com/STOmics/SDAS.git`（由于文件大小限制，github上无sdas-1.0.1.tar.gz和h5ad测试数据）

备注：可以使用wget下载（`wget -O sdas-1.0.1.zip "https://ksc-bj.ag.kdocs.cn/api/object/2_6c05d25c0c8b44c0978a632eaafb8eff/compatible?response-content-disposiame%2A%3Dutf-8%27%27SDAS_1.0.1.zip&KSSAccessKeyId=AKLTU7N1__ODQ4KKf-YhOK9iwg&Expires=1779790554&Signature=6AenFDOR3D"`）

## 3. 安装

<mark style="color:red;">**重要提示!!!**</mark>：解压完成后必须执行setup.sh脚本以确保R路径相关模块正常运行。安装后请勿更改软件安装位置或重命名软件目录，以免导致路径配置失效。

```bash
unzip sdas-1.0.1.zip
tar -xzf sdas-1.0.1.tar.gz
cd sdas-1.0.1
sh setup.sh
```

## 4. 测试运行

```bash
./SDAS -h
```

## 5. 其他说明

* **软件压缩包共30G，解压后70G**
* **关于GPU使用的说明**：请用户自行安装CUDA >= 11.8，参考<https://docs.nvidia.com/cuda/cuda-installation-guide-linux/>
