4.2 Stringtie De Novo Mode

在上一个模块中，使用Stringtie的'-G'和'-e' 选项在'reference only'模式下运行Stringtie

本次教程将运行Stringle的de novo模式

额外选项如下

• '-p 8' tells Stringtie to use eight CPUs
• '-l' name prefix for output transcripts (default: STRG)
• '-o' output path/file name for the assembled transcripts GTF (default: stdout)

mkdir denovo
stringtie -p 8 -l HBR_Rep1 -o denovo/HBR_Rep1/transcripts.gtf HBR_Rep1.bam
