sentence: In this test , we were interested in verifying whether there was a significant increase in the d / d rate in the branch ancestral to the ‘ glabrata group ’ relative to the overall rate and whether this increase also occurred in the different species within the group.To investigate whether pathogenic and non pathogenic species were subjected to different selective pressure , we built two more LRTs to analyse another subset of species focusing on the ‘ glabrata group ’ , we therefore excluded S. cerevisiae , and C. castellii , and used N. bacillisporus as the outgroup ( Additional file 12 ) .
