Book excerpt: This thesis is about the development of methodologies to interrogate RNA-Seq reads derived from non-model organisms. We implemented these methodologies to generate genomic information and describe a useful resource that will promote hypothesis-driven research into the biology of V. inaequalis. In this dissertation three computational approaches are presented that enable optimization of reference-free transcriptome reconstruction. The first addresses the selection of bona fide reconstructed transcribed fragments (transfrags) from de novo transcriptome assemblies and annotation with a multiple domain co-occurrence framework. We showed that selected transfrags are functionally relevant and represented over 94% of the information derived from annotation by transference. The second approach relates to quality score based DNA-seq sub-sampling and the decription of a novel sequence similarity-derived metric for quality assessment of de novo transcriptome assemblies. A detail systematic analysis of the side effects induced by quality score based trimmings and or filtering on artefact removal and transcriptome quality is descibed.
