Method Details

find

Collection<RawExpressionDataVector> find(ArrayDesign arrayDesign,
 QuantitationType quantitationType)

find

Collection<RawExpressionDataVector> find(Collection<CompositeSequence> designElements,
 QuantitationType quantitationType)

getRandomRawVectors

Collection<RawExpressionDataVector> getRandomRawVectors(QuantitationType quantitationType,
 int limit)

Fetch up to limit raw vectors for the given quantitation type, chosen uniformly at random.

Mirrors ProcessedExpressionDataVectorDao#getRandomProcessedVectors: a cheap id-only scan is shuffled in Java and only the picked vectors are fetched (with the design-element / array-design / bioAssayDimension / quantitationType join fetches), avoiding an ORDER BY RAND() sort and a whole-matrix load. Unlike the processed variant there is no rankByMean preference — raw vectors carry no rank, so the sample is uniform.
