Input files

You will need:

  • A STAR index directory (example: STAR_hg38)
  • A genome annotation (example: gencode.v44.annotation.gtf)
  • FASTQ files (we will assume paired files for this tutorial)

Index

If you do not have a STAR index you can create one:

STAR \
  --runThreadN 64 \
  --runMode genomeGenerate \
  --genomeDir STAR_hg38/ \
  --genomeFastaFiles references/hg38.fa \
  --sjdbGTFfile references/gencode.v44.annotation.gtf
