Installation Guide — velocyto 0.17.16 documentation
0.创建新的conda环境 安装velocyto 0.17和python=3.7 等依赖
conda create -n velocytoloom37 python=3.7
conda activate velocytoloom37
conda install -c bioconda velocyto.py
velocyto --help
1.下载物种的特殊的gtf文件
Mask文件到UCSC官网下载

2.运行velocyto run10x 并设置
msk gtf文件的地址
/home/be/besinglecell/OA/gtf/hg38_rmsk.gtf
fastq输出文件的output地址
/home/be/besinglecell/OA/bcoaneiD201/
参考基因的genes的地址
/home/be/besinglecell/referdata/refdata-gex-GRCh38-2020-A/genes/genes.gtf
velocyto run10x -m /home/be/besinglecell/OA/gtf/hg38_rmsk.gtf /home/be/besinglecell/OA/bcoaneiD201/ /home/be/besinglecell/referdata/refdata-gex-GRCh38-2020-A/genes/genes.gtf
velocyto run10x -m /home/be/besinglecell/OA/gtf/hg38_rmsk.gtf /home/be/besinglecell/OA/bcoaneiD201/ /home/be/besinglecell/referdata/refdata-gex-GRCh38-2020-A/genes/genes.gtf
运行20分钟左右会报错 samtools 版本低
conda install -c bioconda samtools=1.6
再次运行后成功
