[DAS] Fwd: Fwd: Problems with myDAS parameters

[Leyla Garcia]

Hi all,

I do not see any problem in the request or response handled by MyDas, 
nor in Dalliance as far as I can tell. MyDas is giving different results 
from those in Dalliance because no type filter has been added.

If I request 
http://genomernai.de/DASGenomeRNAi/das/GenomeRNAiHumanReagentDatasource/features?segment=6:133119869,133155732 
<http://genomernai.de/DASGenomeRNAi/das/GenomeRNAiHumanReagentDatasource/features?segment=6:133119869,133155732;type=RNAi%20phenotype>
I get 4 features, regardless of the type.

However, if I request
http://genomernai.de/DASGenomeRNAi/das/GenomeRNAiHumanReagentDatasource/features?segment=6:133119869,133155732;type=RNAi%20phenotype
Then I get no features, same as Oliver says it happens in Dalliance, 
because the same type filter is being used and none of the features has 
"RNAi phenotype" type. By the way, the %20 was automatically added by 
the browser, originally I used a regular space.

Oliver, does it solve your question? In both cases you are getting the 
same set of results, am I right?
