FRUUT 2.46 – Fast RNA Unrooted Unordered Tree Alignment

FRUUT 2.46

:: DESCRIPTION

FRUUT computes an RNA structure alignment of two given RNA molecules. We generalize previous algorithms that either solved the problem in an asymmetric manner, or were restricted to the rooted and/or ordered cases. Focusing here on the most general unrooted unordered case, we show that our algorithm has an O(nTnS min(dT, dS)) time complexity, where nT and nS are the number of nodes and dT and dS are the maximum node degrees in the input trees T and S, respectively. This maintains (and slightly improves) the time complexity of previous, less general algorithms for the problem.

Unrooted – Draw Binary Tree Expressed in the standard Phylogenetic Tree Format

Unrooted

:: DESCRIPTION

Unrooted is a tree drawing program able to draw any binary tree expressed in the standard phylogenetic tree format (e.g., the format used by the PHYLIP package). Trees are drawn in an unrooted way, that is, using a circular shape, with labels aligned with terminal branches.

urRF – unrooted Gene Trees vs rooted Species Trees

urRF

:: DESCRIPTION

urRF is a new measure based on the standard RF (Robinson-Foulds) distance to compare an unrooted tree with a rooted tree, and describe a linear time algorithm to compute urRF.
