ViewBS:DNA甲基化数据的可视化

官网提供了三种安装方式：conda、docker和正常一步步安装，前两种较为简单，能解决较多的依赖关系，下边介绍一步步安装（https://github.com/xie186/ViewBS）

#安装htslib
git clone https://github.com/samtools/htslib.git
git submodule update --init --recursive
autoreconf
./configure
make
sudo make insatll
#安装ViewBS
wget -c https://github.com/xie186/ViewBS/archive/refs/tags/v0.1.10.tar.gz
tar -zxvf v0.1.10.tar.gz
cd ViewBS-0.1.10
/opt/biosoft/ViewBS-0.1.10/ext_tools/cpanm --local-lib=~/perl5 local::lib && eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)
/opt/biosoft/ViewBS-0.1.10/ext_tools/cpanm Getopt::Long::Subcommand
/opt/biosoft/ViewBS-0.1.10/ext_tools/cpanm Getopt::Long (> 2.50)
/opt/biosoft/ViewBS-0.1.10/ext_tools/cpanm --force Bio::DB::HTS::Tabix

ViewBS主要以Bismark的bismark_methylation_extractor输出结果为输入，同时根据不同的目的需要准备全基因组DNA序列的fasta文件，所有基因的bed文件，转座子bed文件，差异基因的bed文件等。

#数据准备
samtools faidx genome.fasta
bgzip ../A.1_bismark_bt2_pe.deduplicated.CX_report.txt ./ #Bismark结果需要bgzip压缩
tabix -p vcf A.1_bismark_bt2_pe.deduplicated.CX_report.txt.gz #生成tbi结尾的index文件
