  1. Candidate ncRNAs are classified based on either homology with known ncRNAs or overlap with known genomic features. Candidate ncRNAs within each class are further divided into subgroups based on their location relative to known genomic features.
  2. * Each candidate may contain several closely located single ncRNAs, some of which may have already been annotated on the current release of the T. brucei genome. However, at least one ncRNA within each sequence is unannotated, for which a known homolog is found. These unannotated ncRNAs represent novel instances of their classes.
  3. ** These categories may overlap.
  4. *** These categories may overlap.
