ESTs are single-read sequences, typically about \ 500 bases in length, that usually represent fragments of transcribed genes.\
\\ To be considered spliced, an EST must show \ evidence of at least one canonical intron, i.e. one that is at least\ 32 bases in length and has GT/AG ends. By requiring splicing, the level \ of contamination in the EST databases is drastically reduced\ at the expense of eliminating many genuine 3' ESTs.\ For a display of all ESTs (including unspliced), see the \ D. pseudoobscura EST track.
\ \\ This track follows the display conventions for \ PSL alignment tracks. In dense display mode, darker shading\ indicates a larger number of aligned ESTs.
\\ The strand information (+/-) indicates the\ direction of the match between the EST and the matching\ genomic sequence. It bears no relationship to the direction\ of transcription of the RNA with which it might be associated.
\\ The description page for this track has a filter that can be used to change \ the display mode, alter the color, and include/exclude a subset of items \ within the track. This may be helpful when many items are shown in the track \ display, especially when only some are relevant to the current task.

\ \\ To make an EST, RNA is isolated from cells and reverse\ transcribed into cDNA. Typically, the cDNA is cloned\ into a plasmid vector and a read is taken from the 5'\ and/or 3' primer. For most — but not all — ESTs, the\ reverse transcription is primed by an oligo-dT, which\ hybridizes with the poly-A tail of mature mRNA. The\ reverse transcriptase may or may not make it to the 5'\ end of the mRNA, which may or may not be degraded.
\\ In general, the 3' ESTs mark the end of transcription\ reasonably well, but the 5' ESTs may end at any point\ within the transcript. Some of the newer cap-selected\ libraries cover transcription start reasonably well. Before the \ cap-selection techniques\ emerged, some projects used random rather than poly-A\ priming in an attempt to retrieve sequence distant from the\ 3' end. These projects were successful at this, but as\ a side effect also deposited sequences from unprocessed\ mRNA and perhaps even genomic sequences into the EST databases.\ Even outside of the random-primed projects, there is a\ degree of non-mRNA contamination. Because of this, a\ single unspliced EST should be viewed with considerable\ skepticism.
\\ To generate this track, D. pseudoobscura ESTs from GenBank were aligned \ against the genome using blat. Note that the maximum intron length\ allowed by blat is 750,000 bases, which may eliminate some ESTs with very \ long introns that might otherwise align.

It can also tolerate gaps in both\ D. melanogaster and D. pseudoobscura simultaneously. These \ "double-sided" gaps can be caused by local inversions and \ overlapping deletions in both species. \
\ The chain track displays boxes joined together by either single or\ double lines. The boxes represent aligning regions.\ Single lines indicate gaps that are largely due to a deletion in the\ D. melanogaster assembly or an insertion in the D. pseudoobscura \ assembly. Double lines represent more complex gaps that involve substantial\ sequence in both species. This may result from inversions, overlapping\ deletions, an abundance of local mutation, or an unsequenced gap in one\ species. In cases where multiple chains align over a particular region of\ the D. pseudoobscura genome, the chains with single-lined gaps are often \ due to processed pseudogenes, while chains with double-lined gaps are more \ often due to paralogs and unprocessed pseudogenes.
\\ In the "pack" and "full" display\ modes, the individual feature names indicate the chromosome, strand, and\ location (in thousands) of the match for each matching alignment.

The abbreviated genomes were\ aligned with blastz, and the transposons were then added back in.\ The resulting alignments were converted into axt format using the lavToAxt\ program. The axt alignments were fed into axtChain, which organizes all\ alignments between a single D. melanogaster chromosome and a single\ D. pseudoobscura chromosome into a group and creates a kd-tree out\ of the gapless subsections (blocks) of the alignments.

\ \\ In full display mode, the top-level (level 1)\ chains are the largest, highest-scoring chains that\ span this region. In many cases gaps exist in the\ top-level chain. When possible, these are filled in by\ other chains that are displayed at level 2. The gaps in \ level 2 chains may be filled by level 3 chains and so\ forth.

Click\ on a box to view detailed information about the chain\ as a whole; click on a line to display information\ about the gap. The detailed information is useful in determining\ the cause of the gap or, for lower level chains, the genomic\ rearrangement.
\\ Individual items in the display are categorized as one of four types\ (other than gap):
\\ Chains were derived from blastz alignments, using the methods\ described on the chain tracks description pages, and sorted with the \ highest-scoring chains in the genome ranked first. The program\ chainNet was then used to place the chains one at a time, trimming them as \ necessary to fit into sections not already covered by a higher-scoring chain. \ During this process, a natural hierarchy emerged in which a chain that filled \ a gap in a higher-scoring chain was placed underneath that chain. The program \ netSyntenic was used to fill in information about the relationship between \ higher- and lower-level chains, such as whether a lower-level\ chain was syntenic or inverted relative to the higher-level chain. \ The program netClass was then used to fill in how much of the gaps and chains \ contained Ns (sequencing gaps) in one or both species and how much\ was filled with transposons inserted before and after the two organisms \ diverged.
