HLAscan HLA-LA Optitype的HLA分型探索

2020年10月24日 写评论

HLAscan

发现这个软件之前的官网已经打不开，但是在github上仍然在更新，https://github.com/SyntekabioTools/HLAscan或许是换了工作？最近一次更新是2019.12.4，还是比较新的。发现wegene的NGS HLA分型报告是用的这个软件的参考文献，估计还是权威些的。

软件使用方法也有了一些变化，之前只是一个脚本，现在直接编译成了一个独立的可执行文件，运行效率应该也有很大的提高。也省去安装的繁琐。AMD YES的4700U也能跑得动，不错！

安装和运行

for gene in 'HLA-A HLA-B HLA-C HLA-E HLA-F HLA-G
 MICA MICB HLA-DMA HLA-DMB HLA-DOA HLA-DOB HLA-DPA1 HLA-DPB1 HLA-DQA1 HLA-DQB1 HLA-DRA HLA-DRB1 HLA-DRB5 TAP1 TAP2'
 do 
./hla_scan_r_v2.1.4 -l ../read_1.fq -r ../read_2.fq  -d db/HLA-ALL.IMGT  
-t 8  -g $gene 

done

结果

然后就有了结果呀。

HLA-LA

1.软件安装和数据库准备
继续conda，解决软件安装难题，也不需要挑战有些门槛的docker。

## 安装
 conda install hla-la
 ## 数据库下载
 cd ~/miniconda3/opt/hla-la/
 mkdir graphs
  wget http://www.well.ox.ac.uk/downloads/PRG_MHC_GRCh38_withIMGT.tar.gz
tar -xvzf PRG_MHC_GRCh38_withIMGT.tar.gz
# 数据库索引，这步要耗30G的内存。。。，我这16G ram的笔记本靠swap扛着，速度就慢了不只一点了
cd ~/miniconda3/opt/hla-la/bin/
 ./HLA-LA --action prepareGraph --PRG_graph_dir ../graphs/PRG_MHC_GRCh38_withIMGT

2.用起来，分型

就简单的几个参数，8核，速度也就慢慢跑了，不知道会不会报错。

HLA-LA.pl --BAM ./2hla_sorted.bam   --graph PRG_MHC_GRCh38_withIMGT --sampleID 10 --maxThreads 8  --workingDir ./

然后在swap+ram达到极限的70G的时候停止运行了。
gihub上看到这个issue我有点绝望了，我的硬件达不到这水平呀！

my paired-end fastq file:
R1.fastq (250 Million reads, 150bp, ~1.2 GB)
R2.fastq (250 Million reads, 150bp, ~1.2 GB)
run HLA-LA will used about 300~400 GB RAM and ~90GB swap

Optitype

软件安装

最开始尝试使用docker，无奈悲剧的失败，发现bioconda有这个软件的，于是上conda，感觉比docker更方便呢。还有一个好处是，win10家庭版不支持docker，要想支持得修改注册表一通操作，太麻烦了。

# 下面两个命令选一就可以了
conda install -c bioconda optitype 
conda install -c bioconda/label/cf201901 optitype

运行和结果

很简单的一条命令就可以了。

 OptiTypePipeline.py  -i read_1.fq read_2.fq --dna -v -o optutype

AMD YES的r7-4700u加持下，在近乎突破硬件极限的情况下完成了分型。
结果首先是个pdf文件，是分型结果的测序覆盖度图。
在这里插入图片描述
然后是一个tsv文件，分型结果，是只有ABC的结果，4位的：

        A1      A2      B1      B2      C1      C2      Reads   Objective
0       A*03:01 A*31:01 B*15:11 B*48:01 C*03:03 C*08:01 15556.0 15135.987999999903
