You're not going crazy. It's just that all the servers to date have chosen to 
implement the client-side form of link (where the link information is 
returned gratis with every feature record) rather than implement server-side 
link. The servers should be returning an empty record, are they?

That makes some sense. The servers are returning an empty record so it
sounds like that is what they are supposed to do. That means the
information I am looking for is in the results of the 'feature' command(?).

Does an example scenario (using the wormbase server) become?
http://www.wormbase.org/db/das/dsn. Returns the list of data sources on
this server. The only server that is returned is 'elegans'
http://www.wormbase.org/db/das/elegans/entry_points. Returns a list of
entry points. For the purpose of this discussion I will select
   Sequence" id=X subparts="yes" orientation="+" stop="17683571" start="1" size="17683571">X

http://www.wormbase.org/db/das/elegans/features?segment=X:1,100000.
Returns a list of features against this segment. Many feature records
are returned (around 300). An example record is:

  
curated exon
  curated
  24479
  24819
  -
  -
  
0


  
              http://www.wormbase.org/db/get?name=Y73B3A.1;class=Sequence">
Y73B3A.1
  
  


I see the "link" which is part of the . Is that the
annotation or does this entry not have one since there is no 

under the feature tag? Actually none of the entries have a 

parameter under the feature tag. If one exists it is in the
section. Am I getting closer?

Thanks again!

It's just that all the servers to date have chosen<BR>to<BR>implement the client-side form of link (where the link information is<BR>returned gratis with every feature record) rather than implement<BR>server-side<BR>link. The servers should be returning an empty record, are they?<BR><BR>Lincoln<BR><BR>On Friday 27 September 2002 11:46 am, Dave Wall wrote:<BR>&gt; Geoff and I are stumped.

There is evidence that "link" works on the<BR>Sanger<BR>&gt; DAS server as the pop-up menus are populated with additional information.<BR>&gt; However, I've been unable to access that information using a script.<BR>&gt;<BR>&gt; I suggest posting your question on the biodas list. The collective<BR>&gt; expertise on the list is orders of magnitude greater than my own.<BR>&gt;<BR>&gt; I don't know of any alternatives to "link" for accessing annotation<BR>&gt; details.<BR>&gt; The reason I quoted "link" is that command names appear in italics in the<BR>&gt; DAS documentation and italics isn't available in a plain text message.<BR>&gt;<BR>&gt; &gt; -----Original Message-----<BR>&gt; &gt; From: Dave Wall [mailto:dawall@us.ibm.com]<BR>&gt; &gt; Sent: Thursday, September 26, 2002 5:29 PM<BR>&gt; &gt; To: Geoff Purdy<BR>&gt; &gt; Subject: RE: [DAS] Getting Started With DAS<BR>&gt; &gt;<BR>&gt; &gt;<BR>&gt; &gt;<BR>&gt; &gt; Thanks for looking into it. If I read between the lines a little it<BR>&gt;<BR>&gt; almost<BR>&gt;<BR>&gt; &gt; sounds as if there is another way to get the annotation. You tried<BR>&gt;<BR>&gt; three<BR>&gt;<BR>&gt; &gt; servers and none of them delivered the data via the link command. Is<BR>&gt;<BR>&gt; there<BR>&gt;<BR>&gt; &gt; another way to do it?<BR>&gt; &gt;<BR>&gt; &gt; David Wall<BR>&gt; &gt; 553-5329<BR>&gt; &gt; IBM Life Sciences<BR>&gt;<BR>&gt; Dave,<BR>&gt; You raise a good point here. I notice that if I use the link command on<BR>&gt; three different das servers, I see three different behaviors.<BR>&gt;<BR>&gt; Last I saw, the UCSC DAS server was Jim Kent's C implementation of the<BR>DAS<BR>&gt; specification. As you pointed out, the link command gives no output (in<BR>&gt; the<BR>&gt; handful of cases I've tried).<BR>&gt;<BR>&gt; I also tried a similar query on the Sanger Center DAS server (a Java<BR>&gt; implementation, I believe). This server gives the following message if a<BR>&gt; feature doesn't have associated annotations:<BR>&gt; 
<H1>No extra information about this object</H1><BR>&gt; 
<P>field: feature<BR>id: 18/p11.32</P><BR>&gt;<BR>&gt; Finally, I tried CSHL's wormbase DAS server (a perl implementation by<BR>&gt; Lincoln Stein). This doesn't seem to implement the link command at all.<BR>&gt;<BR>&gt; I notice that the "link" command is an annotation server specific command<BR>&gt; (not part of reference server specification). I'm unsure which of these<BR>&gt; servers purport to be reference, annotation, or both. Another<BR>possibility<BR>&gt; is that different implementations of DAS may omit implementing portions<BR>of<BR>&gt; the specification.<BR>&gt;<BR>&gt; I'll give this a closer look, but I'm beginning to think this might be a<BR>&gt; good subject for on-list discussion.<BR>&gt;<BR>&gt; &gt; -----Original Message-----<BR>&gt; &gt; From: Dave Wall [mailto:dawall@us.ibm.com]<BR>&gt; &gt; Sent: Thursday, September 26, 2002 4:15 PM<BR>&gt; &gt; To: Geoff Purdy<BR>&gt; &gt; Subject: RE: [DAS] Getting Started With DAS<BR>&gt; &gt;<BR>&gt; &gt;<BR>&gt; &gt;<BR>&gt; &gt; Thanks for offering to help!<BR>&gt; &gt;<BR>&gt; &gt; I have been having pretty good luck getting a list of data<BR>&gt; &gt; sources, types,<BR>&gt; &gt; segments, etc., but crash when I trying to get an annotation.<BR>&gt; &gt; Here is an<BR>&gt; &gt; example for the purpose of verifying URL syntax ...<BR>&gt; &gt;<BR>&gt; &gt;<BR>&gt; &gt; http://genome.cse.ucsc.edu:80/cgi-bin/das/hg12/features?segmen<BR>&gt; &gt; t=18:1,100000<BR>&gt; &gt;<BR>&gt; &gt; In the returned data is<BR>&gt; &gt; - <FEATURE id=GC.chr18.60000 label="GC"><BR>&gt; &gt; <TYPE id=gcPercent reference="no" category="other">GC<BR>&gt; &gt; Percent</TYPE><BR>&gt; &gt; <METHOD></METHOD><BR>&gt; &gt; <START>60001</START><BR>&gt; &gt; <END>80000</END><BR>&gt; &gt; <SCORE>0</SCORE><BR>&gt; &gt; <ORIENTATION>0</ORIENTATION><BR>&gt; &gt; <PHASE>-</PHASE><BR>&gt; &gt; - <GROUP id=GC.chr18.60000><BR>&gt; &gt; <LINK href="<br>> ><br>> > http://genome.ucsc.edu/cgi-bin/hgTracks?position=chr18:60000-8<br>> > 0000&amp;db=hg12<br>> >               ">Link to UCSC Browser</LINK><BR>&gt; &gt; </GROUP><BR>&gt; &gt; </FEATURE><BR>&gt; &gt;<BR>&gt; &gt; I then send the following which returns a blank page.<BR>&gt; &gt;<BR>&gt; &gt; http://genome.cse.ucsc.edu/cgi-bin/das/hg12/link?field=feature<BR>&gt; &gt; ;id=GC.chr18.60000<BR>&gt; &gt;<BR>&gt; &gt; I am probably missing something obvious, but I sure can't<BR>&gt; &gt; figure out what<BR>&gt; &gt; it is.
