The future of transposable element annotation and their classification in the light of functional genomics - what we can learn from the fables of Jean de la Fontaine?

Peter Arensburger, Benoît Piégu, Yves Bigot
2016 Mobile Genetic Elements  
Our hope is to encourage the formation of a society to organize a larger debate on these questions and to promote the adoption of standards for annotation and an improved TE classification.  ...  Today, whole genome TE annotation is mostly done using tools that were developed to aid gene annotation rather than to specifically study TEs.  ...  The authors of RepeatMasker have attempted to address the third problematic issue (very divergent repeats) by introducing Dfam 11 which uses hidden Markov models and sequence alignments instead of simple  ...
