Inevitably with automated sequence analysis, we find exceptions to
general identification rules, isoacceptor type predictions
(esp. due to variable post-transcriptional anticodon
modification), and questionable tRNA identifications (due to
pseudogenes, SINES, or other tRNA-derived elements). We attempt to
document all cases we come across, and welcome feedback (lowe @soe.ucsc.edu) on new
or unrecognized discrepancies. For a more detailed description of
information in tables and the tRNA search algorithm, see the [Legend].
