 If a genomic DNA profile is selected, the input reference must be the **reference genome in *FASTA* format**. *squigulator* will randomly sample the genome from a uniform distribution and generate reads whose lengths are from a gamma distribution (based on `-r`). If a direct RNA profile is selected, the input reference must be the **transcriptome in *FASTA* format**. For RNA, *squigulator* will randomly pick transcripts from a uniform distribution and the whole transcript length is simulated.
