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）
网址：http://software.broadinstitute.org/gsea/index.jsp
遇到问题: (集中在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：
1. ##查看电脑 java 版本
java -version
2.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
