可变剪切画图
- 创建一个python=2.7的环境
conda create -n rmats402 python=2.7
- 进入环境
conda activate rmats402
- 下载作图软件
conda install -y rmats2sashimiplot
- 根据rmats结果提取想要的基因
- 第一种方法：先挑出想要的基因，记录每个基因的行号和来自哪个文件，使用sed命令提取这些行号
sed -n '1p;552p;553p;984p;1382p;1980p;2590p;4064p;4655p;4883p;4884p;6222p;6500p;6621p;7534p;7870p;7871p;7872p;8953p;8962p;11164p;11989p;12544p;13226p;13474p;13577p;14115p;14116p;15476p;17042p;17043p;17517p' SE.MATS.JC.txt > ../../YG.SE.MATS.txt
- 第二种方法： 记录每个基因ID号，使用awk命令提取带有ID号的这些行
cat A3SS.MATS.JC.txt | awk '$1=="ID" || $1==13 {print$0}' > ../../YG.A3SS.MATS.txt
cat A5SS.MATS.JC.txt | awk '$1=="ID" || $1==291 {print$0}' > ../../YG.A5SS.MATS.txt
cat MXE.MATS.JC.txt | awk '$1=="ID" || $1==1326 || $1==1484 || $1==1490 {print$0}' > ../../YG.MXE.MATS.txt
cat SE.MATS.JC.txt | awk '$1=="ID" || $1==550 || $1==551 || $1==982 || $1==1380 || $1==1978 || $1==2588 || $1==4062 || $1==4653 || $1==4881 || $1==4882 || $1==6220 || $1==6498 || $1==6619 || $1==7532 || $1==7868 || $1==7869 || $1==7870 || $1==8951 || $1==8960 || $1==11162 || $1==11987 || $1==12542 || $1==13224 || $1==13472 || $1==13575 || $1==14113 || $1==14114 || $1==15474 || $1==17040 || $1==17041 || $1==17515 {print$0}' > ../../YG.SE.MATS.txt
- 处理sort.bam文件 不处理也会报错
samtools view -H H1_sort.bam | sed -e 's/SN:\([0-9XY]\)/SN:chr\1/' -e 's/SN:MT/SN:chrM/' | samtools reheader - H1_sort.bam > H1_sort_chr.bam
samtools view -H H2_sort.bam | sed -e 's/SN:\([0-9XY]\)/SN:chr\1/' -e 's/SN:MT/SN:chrM/' | samtools reheader - H2_sort.bam > H2_sort_chr.bam
samtools view -H H4_sort.bam | sed -e 's/SN:\([0-9XY]\)/SN:chr\1/' -e 's/SN:MT/SN:chrM/' | samtools reheader - H4_sort.bam > H4_sort_chr.bam
samtools view -H L1_sort.bam | sed -e 's/SN:\([0-9XY]\)/SN:chr\1/' -e 's/SN:MT/SN:chrM/' | samtools reheader - L1_sort.bam > L1_sort_chr.bam
samtools view -H L3_sort.bam | sed -e 's/SN:\([0-9XY]\)/SN:chr\1/' -e 's/SN:MT/SN:chrM/' | samtools reheader - L3_sort.bam > L3_sort_chr.bam
samtools view -H L2_sort.bam | sed -e 's/SN:\([0-9XY]\)/SN:chr\1/' -e 's/SN:MT/SN:chrM/' | samtools reheader - L2_sort.bam > L2_sort_chr.bam
- 运行命令SE格式
rmats2sashimiplot --b1 H1_sort_chr.bam,H2_sort_chr.bam,H4_sort_chr.bam --b2 L1_sort_chr.bam,L2_sort_chr.bam,L3_sort_chr.bam -t SE -e ./YG.SE.MATS.txt --l1 H --l2 L --exon_s 1 --intron_s 1 -o YG_SE_MATS_plot
- 运行命令 A5SS格式
rmats2sashimiplot --b1 H1_sort_chr.bam,H2_sort_chr.bam,H4_sort_chr.bam --b2 L1_sort_chr.bam,L2_sort_chr.bam,L3_sort_chr.bam -t A5SS -e ./YG.A5SS.MATS.txt --l1 H --l2 L --exon_s 1 --intron_s 1 -o YG_A5SS_MATS__plot
- 运行命令 A3SS格式
rmats2sashimiplot --b1 H1_sort_chr.bam,H2_sort_chr.bam,H4_sort_chr.bam --b2 L1_sort_chr.bam,L2_sort_chr.bam,L3_sort_chr.bam -t A3SS -e ./YG.A3SS.MATS.txt --l1 H --l2 L --exon_s 1 --intron_s 1 -o YG_A3SS_MATS__plot
- 成功运行

- 如果是自己创建输入文件，则会出现下面的bug
