The selection of the best hypothesis model was based on the total cost, predictive ability, difference in the cost from the null hypothesis and alignment of the training set compounds on to the hypothesis.
Critical plane oriented hypotheses can consider these different parameters, but the difficulty lies in the definition of ductility and, based on this, the selection of the appropriate hypothesis.
These patterns, along with signals from a categorical enrichment of branch-specific estimates of selection, support the hypothesis that changes in the adult habitat of A. fragilis have induced rapid protein evolution.
This plant pathogen system provides a unique opportunity to address two questions using phylogenetically based analyses, including: 1. Do PCWDEs show molecular evidence of positive selection supporting the hypothesis of a co-evolutionary arms-race between plant and pathogen?
To investigate further, the calculation of Ka/Ks ratio was extended to all 100 commelinids used in this phylogenetic study (Additional file 6) and to simplify the calculation for 100 sequences of rps7 gene, the calculation was performed using Codon-based Z test of selection to test the hypothesis of positive selection (null hypothesis: strict-neutrality (dN = dS)) (dN/dS is equivalent to Ka/Ks).
This experiment provides a positive in vivo selection for validation of the hypothesis, in contrast to the dramatic decrease in accumulation of the proteins when ligands are removed by substitution with non-ligand amino acids [ 42].
Combined, the two can be used for the greedy selection of the next base hypothesis.
The tumor samples were collected from patients prior to treatment and prior to the selection of the primary biomarker hypothesis or the validation of the HRG assay method.
However, the implications of the selection of models and hypothesis adopted and their impact on the structural response have not been thoroughly highlighted yet.
Duplicated genes identified with this approach were further studied to test for evidence of positive Darwinian selection and whether the hypothesis for the retention of duplicated genes and the evolution of novel gene functions in one copy is supported.
