Hi,

Does anyone know how I can access introns and exons for fruit fly (dm2) 
through DAS? I've looked at the refGene and flyBaseGene types but they 
seem to lack this information. Is there a webpage which gives an 
overview of what is available through DAS?


The FAQ (http://genome.ucsc.edu/FAQ/FAQdownloads.html#download23) states:

For example, here is a query that returns all the records in the refGene 
table for the chromosome position chr1:1-100000 on the hg16 assembly:

http://genome.ucsc.edu/cgi-bin/das/hg16/features?segment=1:1,100000;type=refGene



but when I run it each feature returned looks like:
<FEATURE id="NR_026822.chr1.24474.2" label="NR_026822">
  <TYPE category="transcription" id="refGene" reference="no">RefSeq 
Genes</TYPE>
  <METHOD />
  <START>25584</START>
  <END>25944</END>
  <SCORE>-</SCORE>
  <ORIENTATION>-</ORIENTATION>
  <PHASE>-</PHASE>
  <GROUP id="NR_026822.chr1.24474">
   <LINK 
href="http://genome.ucsc.edu/cgi-bin/hgTracks?position=chr1:24474-25944&amp;db=hg16";>Link
 
to UCSC Browser</LINK>
  </GROUP>
</FEATURE>


whereas the documentation for the refGene table 
(http://genome.ucsc.edu/cgi-bin/hgTables?db=dm2&hgta_group=genes&hgta_track=refGene&hgta_table=refGene&hgta_doSchema=describe+table+schema)
suggests there is much more information in the table, including exon 
locations.


Thanks,
John.
