I am a newbie in RNA-seq analysis. I would like to use HISAT2 for RNA-seq alignment. In HISAT2 website, I found that pre-built index have genome_snp_tran of grcm38 and genome of mm10. I was wondering if I could use mm10 genome for RNA-seq alignment? If I cannot, I was wondering how can build an index for mm10 RNA-seq alignment. Thanks!
