Problems to index reference genome and to align RNAseq
written by silas008I'm trying to align RNAseq data with STAR aligner. The reference genome for mice is split in 1-22 + X,Y and MT. Should I create …
Have you gone through the manual here. In addition to the genome fasta file, you would also need a GTF file (of gene annotations) to build the STAR index.
Yes, I know also need a GTF file. So the GTF file will include RNA information? Thanks for your answer!!
GTF file includes gene models/annotation information.
You could also use a program like
salmon/kallistowith just human transcriptome to do similar analysis.But I am going to do variant calling later, so I think STAR is more appropriate. Thank you.
