The RfamSeed track shows ncRNAs from the RNA families database at the Wellcome Trust Sanger Institute.
Human entries from Rfam were extracted and aligned against the human genome using blat. The Rfam database is described in Griffiths-Jones, S. et al. (2003) below.
If you make use of these data, please cite the Rfam article listed in the References section in addition to the primary data sources.
