Nucleic Acids Research, 2011, Vol. 39, Database issue D573 Figure 3. Branch support in PhEVER trees. (A) Histogram of node supports in all phylogenetic trees. The dashed line indicates the support value of 70 (80% of the distribution is above this threshold), the dotted line indicates the support value of 95 (one-third of the distribution is above this threshold). (B) Relation between the mean node support in a family and the size of this family, measured by the number of nodes in the family. The inner ﬁgure shows the mean node support of the smaller families. (C) Relation between branch support and branch length. Only branch lengths inferior to 1 are plotted on this ﬁgure. The inner ﬁgure shows the distribution of branch lengths justifying the focus on branch lengths inferior to 1. For all ﬁgures, only trees with more than four leaves are presented here. Branches with length smaller than 10 5 were considered unresolved multifurcations and were discarded. Figure 4. Overview of some of the possibilities of the PhEVER interface. (A) HoSeqI tool to query PhEVER families with a user provided sequence, (B) Query the database with terms including gene name, species name, annotation terms, (C) Alignments and phylogenies can be recomputed on the ﬂy through the HoSeqI tool, (D) Visualization of a PhEVER family and the species and sequences composing it, (E) JalView applet to edit the pre-computed alignments and (F) ATV applet to edit the pre-computed phylogenies.
