• 当使用snpEff创建数据库的时候使用以下命令

java -jar snpEff.jar build -gtf22 -v Oar_rambouillet_v1.0

• 突然报错

如果发现此错误，则意味着gtf文件中有一些基因，而fasta文件中没有
因此，我们只需要在gtf文件中删除该基因即可

• 解决办法 参考（https://github.com/pcingola/SnpEff/issues/230）

sed -i "/ENSOART00020027463/d" genes.gtf

• 运行成功 okkkkkk

• 确认一下

#如果成功那么在Oar_rambouillet_v1.0目录下会有一个".bin"文件产生
(base) [jychu@localhost snpEff]$ cd data/Oar_rambouillet_v1.0/
(base) [jychu@localhost Oar_rambouillet_v1.0]$ ls
genes.gtf  snpEffectPredictor.bin

该BUG解决！
