Summary: SEPON, Selection and Evaluation Pipeline for OligoNucleotide generates n-mer oligonucleotide sequences from expressed sequence tags of non-annotated genomes for microarray gene-expression profiling. A non-target melting temperature (Tm) algorithm will reduce cross-hybridization by estimating Tm of oligonucleotide hybridization to non-specific targets (non-target Tm) and discard oligonucleotides with non-target Tm estimate above user-defined threshold. SEPON allows user-defined filtering, predicts exon location, assigns penalty based on 3' distance, GC content, secondary structure Tm and non-target Tm and ranks oligonucleotides for optimal selection.
