Positive and negative selection analysis of the chIFITM proteins. a-c-e Positive selective pressure on chIFITM residues. Residues with Prob[a < b] value over 0.9 is considered as under episodic positive/diversifying selection using FUBAR. b-d-f Negative selective pressure on chIFITM residues. Residues with Prob[a > b] value over 0.9 is considered as under episodic negative/purifying selection using FUBAR
