二、分析流程
cd /data/user/sam/project/scBCR/1.analysis/input/X101SC20090516-Z01-J001
1.质控 150m,g01
source /data/user/sam/project/meta/miniconda2/bin/activate root
conda activate metawrap-env
export PERL5LIB=/data/user/sam/project/meta/miniconda2/envs/metawrap-env/lib/5.26.2/
time metawrap read_qc -1 Rawdata/G_MB_1/G_MB_1_1.fastq.gz -2 Rawdata/G_MB_1/G_MB_1_2.fastq.gz -t 60 -o 1.clean_data/G_MB_1 --skip-bmtagger
cd /data/user/sam/project/scBCR/1.analysis/input/X101SC20090516-Z01-J001/1.clean_data/G_MB_1
mv G_MB_1_1_val_1.fq.gz G_MB_1_S1_L001_R1_001.fastq.gz
mv G_MB_1_2_val_2.fq.gz G_MB_1_S1_L001_R2_001.fastq.gz
conda deactivate
2. vdj聚类（4个小时，50核）
