# 编译
通过阅读压缩包中的README文件，了解如何编译它。
tar zxvf nciplot-3.0.tar.gz
cd nciplot-3.0
cd src
sed -i "s/FCFLAGS = -O2 -fopenmp/FCFLAGS = -O3 -fopenmp/" Makefile.inc
make mrproper
make

说明：
Makefile.inc文件用来指定编译器和编译参数是，默认是gfortran编译器。- 上面的编译过程非常简单，我们仅仅把优化级别改为了
-O3，其他不用改。 - 它还支持
ifort编译器。
# 配置运行环境
我们需要配置相关环境来保证软件运行。
export NCIPLOT_HOME=/home/nciplot-3.0
export PATH=$NCIPLOT_HOME/src:$PATH
export OMP_NUM_THREADS=4

说明：
NCIPLOT_HOME是软件解压缩后的目录，该目录下需要包含名为dat的文件夹，软件运行需要。- 设置
PATH环境变量是为了方便直接调用nciplot命令。 - 设置
OMP_NUM_THREADS是因为该软件支持多线程运行，该参数设置多线程数，这样可以加速。本实例中写为4，说明软件运行时会开启4个线程。
# 测试
我们进入test目录，运行算例看一下。
cd test-cases/adenin-thymine
nciplot AT.nci

如果运行顺利，可以获得如下运行结果：
