背景：Gene Set Enrichment Analysis (GSEA) is a computational method that determines whether an a priori defined set of genes shows statistically significant, concordant differences between two biological states. (官网下载需填邮箱)

GSEA

遇到问题(Java版本): 1. GSEA运行需要Java； 2. 电脑自带Java,打不开GSEA

发现问题: GSEA支持java 版本(java 8)与电脑Java版本（java 11.0.1）不匹配。(在下载的时候有提示java版本，没看说明导致！！！)

解决问题：

 ##查看电脑 java 版本
java -version

我选择用conda安装java 8

##根据你自己的电脑来选择性安装conda
wget https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/Miniconda3-latest-Linux-x86_64.sh

# 然后修改镜像，加快下载速度
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda

conda config --set show_channel_urls yes

##安装
sh Miniconda3-latest-Linux-x86_64.sh

## 把java8安装到指定环境，隔离开来
conda create -n qc

source activate qc

conda install openjdk=8.0.152

##版本成功，查看java版本
java -version

##运行：
java -jar gsea-3.0.jar

很多broad institute出品的软件都依赖于 java8

## 想了解版本，
conda search openjdk
