By Rahul Nayak 3050 days agogithub.com - Porechop is a tool for finding and removing adapters from Oxford Nanopore reads. Adapters on the ends of reads are trimmed off, and when a read has an adapter in its middle, it is treated as chimeric and chopped into separate reads. Porechop...ChopStitch: exon annotation and splice graph construction using transcriptome assembly and whole...
