It takes account of any gaps (insertions, deletions, exon–exon junctions or fusions) that are found in the read.

WebIf you did in fact align to the genome, do note that the in-built annotation is based on NCBI Gene IDs, and GenCode is based on EBI/EMBL, so the chromosome in the first instance will be e.g., chr1, whereas in the second it will be just 1. You will probably either need to generate an SAF file, or get a GFF or GTF file from GenCode.
