[DAS] DASSequence.java behaves somehow strange

[Thorsten Jansen]

Hi,
testing my dasclient classes I recognized that the actual build from biojava
and the build from 18.10.2002 show different behaviour in loading the
sequence string using the DASSequence class (used method:
dasSeq.subList(startPos,stopPos).seqString()). Using the ensembl (homo
sapiens 8.30) data as reference server the following happens:

Using new build: Loading the sequence for chromosome 1 from position 30001
to 40000 results in a "normal" sequence string from 30001 to 33556. From
33557 to 40000 only "N"s are listed. This is somehow related to the shown
features "AC114498 (1 to 33556)" and "AL669831 (33557 to 212222)".

Using old build (18.10.2002): Loading the sequence for chromosome 1 from
position 30001 to 40000 results in a "normal" sequence string from 30001 to
40000. No "N" characters are listed.

Using dasserver directly: Using the dasserver via an webbrowser (das
command) gives back an xmlpage with the complete sequence (without "N"
characters).

Who knows something about the changes in biojava/biodas? Is this new
behaviour biologicaly correct or is it a bug.

Thanks
Thorsten
