- SURVIVOR
命令
${SURVIVOR_path}/SURVIVOR merge sample_files 1000 1 1 1 0 30 sample_merged.vcf
这里的sample_files里面是vcf文件路径,一行一个vcf文件,不使用压缩格式
# merge 合并选项;
# sample_files 待合并的 vcf 文件 list;
# 1000 起始和终止位点的坐标相差均不大于 1000 bp 即合并;
# 2 只输出至少有 2 个 callers 的变异; 当其他软件合并后SV数量更多时候,检查这里设置为1是否可以
# 1 SV 的 type 需要保持一致;
# 1 SV 的方向 strand 需要保持一致;
# 0 这个0是个啥?
# 30 只输出 30 bp 以上的 SVs;
官网文档:
This will merge all the vcf files specified in sample_files together using a maximum allowed distance of 1kb, as measured pairwise between breakpoints (begin1 vs begin2, end1 vs end2). Furthermore we ask SURVIVOR only to report calls supported by 2 callers and they have to agree on the type (1) and on the strand (1) of the SV. Note you can change this behavior by altering the numbers from 1 to e.g. 0. In addition, we told SURVIVOR to only compare SV that are at least 30bp long and print the output in sample_merged.vcf.
For simply merging different SV set one can set the minimum required support by caller to 1 instead of 2 and retrieve a union set across all samples.
软件带来的后续问题:
软件合并SV后,会导致和初始ref序列不匹配,导致构建泛基因组过程中出现问题:
vg的github问答区也有类似现象https://github.com/vgteam/vg/issues/4318 怀疑这个人也用的SURVIVOR
暂时没时间弄清楚发生了什么,暂时不使用SURVIVOR
提取ins和del测试仍旧失败。
又发现一个教程:https://www.jianshu.com/p/5b86aa774e3f 这里给了解决办法,有时间去测试。
