Query Interface

• Query for experiments by certain criteria (name, type, species, ...)

• Display of hybridizations, samples, arrays, reporters

Query Interface

• Query for experiments by certain criteria (name, type, species, ...)

• Display of hybridizations, samples, arrays, reporters

• Simple statistic analysis– Distribution– Normalized ratios– T-test

Current Content

• 19 experiments, 103 hybridizations• 79 arrays of 42 array designs• 64 bio sources• 370 protocols• Sources: inhouse, collaborations

Implementation

• Oracle• Tomcat• Java, Perl

– Generated APIs from Oracle data dictionary•Object-relational mapping•Database interface

• R, Bioconductor

Problems

• Data aquisition• Data not MIAME compatible• Performance

Next Steps

• Automated analysis pipeline• Further cooperations with new partners• User training• Integration into RZPD system (clone

ordering)• Use functional annotations for analysis• Combine text mining with analysis

Thank you!
