MPSS signatures detected in Lynx mouse transcriptome analysis experiment.
To generate a complete, annotated mouse signature database, we extracted all the possible signatures (“virtual signatures”) from the mouse genome sequence (NCBI build 33) and the mouse UniGene sequences (UniGene build #145). Each virtual signature is ranked based on its position and orientation in the original sequence. The annotation for that sequence is then assigned to the signature and the resulting signature database is used to annotate the data from the experiments, using our “TopHit” algorithm.
