Hi Dan,

If there is more than one exon for a particular transcript, the results 
for that transcript are ordered by chromStart, but then additional 
transcripts will not necessarily be sorted relative to one another.

If you need the output to be ordered by position, the UNIX/gnu sort 
command can do that easily:

   sort -k1,1 -k2n,2n myFile > mySortedFile

Additionally, you should be aware that some non-coding genes are showing 
up in your results.  If you would like to exclude those genes, you can 
add a filter in the Table Browser.  Hit the "filter: create" button, and 
then in the "Free-form query" box add "cdsStart != cdsEnd" (without the 
quotes).  Genes with no coding region (CDS) appear in our tables with 
the same number for cdsStart and cdsEnd, so this filter will keep those 
genes from appearing in the output.

We are going to look into changing the options in the Table Browser so 
that non-coding genes will not appear in the results when the 3'UTR or 
5'UTR output types are selected.

I hope this information is helpful.  If you have further questions, 
please contact us again at [email protected].
