[可能需要用到的加速服务](/-ji-lu-SOCKS5-zhuan-QUIC) ### SRA工具 ```bash conda create -n sra_tools -c bioconda sra-tools conda activate sra_tools conda install -c conda-forge lftp -y conda install -c conda-forge pigz -y # 或许换成 pbgzip 更好，此时将 -p 换成 -n 来指定线程数 conda install -c bioconda pbgzip -y prefetch # vdb-config -i # 设置 HTTP 代理 ``` ### GATK4 ```bash conda create -n GATK4 -c bioconda gatk4 conda activate GATK4 conda install -c bioconda samtools -y conda install -c bioconda bwa -y conda install -c bioconda pbgzip -y # 并行版bgzip，bgzip是修改过的gzip，更适合生信领域 conda install -c bioconda tabix -y # 操作VCF文件，与bgzip配套 # conda install -c bioconda fastqc -y # 改用fastp了 # conda install -c bioconda trimmomatic -y # 改用fastp了 conda install -c bioconda fastp -y # conda install -c bioconda bcftools -y # 用于重命名染色体 # ln -s $CONDA_PREFIX/lib/libgsl.so $CONDA_PREFIX/lib/libgsl.so.25 # 无效，放弃 # conda create -n GATK4-VEP -c bioconda ensembl-vep -y # 根正苗红的突变注释软件，不懂有什么奇怪依赖，解析环境半天 ``` + BWA是DNA比对工具(不会跨外显子比对)，[STAR](/STAR--yi-jian-jiao-ben)是RNA比对工具 + [找SNP不推荐用RNAseq的数据](https://zhuanlan.zhihu.com/p/37345954) + [各种比对工具的说明](https://www.jianshu.com/p/601469194b5e) ## 准备数据 ### 参考数据 + [NCBI上各物种的参考序列](https://www.ncbi.nlm.nih.gov/genome/browse)，可以找到RefSeq，比如Human是GCF_000001405 + 知道序号后可以到[FTP](https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/)上下载相应的`genomic.fna.gz`文件 + 比如GCF_000001405，依次进入`000/001/405`即可找到对应的文件 ```bash wget https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/001/405/GCF_000001405.40_GRCh38.p14/GCF_000001405.40_GRCh38.p14_genomic.fna.gz -O
