This feature allows to span corresponding intron sequences on the genomic sequence or junction sequences between exons.
Note that this feature is only available for mRNA/cDNA sequences with annotated exons. There are several ways to obtain the cDNA for a corresponding DNA sequence.
- From NCBI or ENSEMBLE database
- Align the genomic and cDNA sequences using spliced aligner
