Summary
Reliable and robust pipeline
Study and compare whole genomes
Focus on particular features
Partition into areas of interest
Visualize and summarize the data
Key evolutionary questions
Intron test case has been very insightful
Future directions
Introns
Homology, Ontology, Synteny, Gene families
Evolutionary questions
Expansion of studies
52 genomes
Phylogenetic comparisons
Thank you!
Any questions?
