Hi Jim,

I'm sorry, but I'm not quite sure how you were going to cross check your 
sequencing data, so I am not sure if RefSeq Genes, and thus refFlat, is 
a good track to use. You can always find out more information about a 
track, and thus it's tables, by reading the description pages (RNA 
Genes: http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=rnaGene, 
RefSeq Genes: http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=refGene)

While the RNA Genes track is a good start, you may also want to check 
out other tracks in the mRNA and EST track group here: 
http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg18. Clicking on the track 
name will take you to a description page, with more information about 
the track. You may also be interested in the tRNA Genes 
(http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=tRNAs) and sno/miRNA 
tracks (http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=wgRna).

I hope this information is helpful.  Please feel free to contact the 
mail list again if you require further assistance.

Best,
Mary
