Phylocom

Features (Current version: 4.2)

• Calculate phylogenetic community structure metrics (Webb's NRI, NTI, Faith's PD, Rao's entropy) and compare observed patterns to those expected under various null models of community assembly and phylogeny structure (comstruct). Now, many metrics incorporate variation in taxon abundance.
• Calculate inter-sample phylogenetic distance for phylogenetic ordination and classification (comdist and comdistnt). Now incorporates null model testing of observed patterns.
• Comparative methods for the analysis of character evolution (aot; conservatism metrics, independent contrasts, lineages through time).
• Calculate trait distribution metrics within sample communities and compare to metrics for random community assembly (comtrait).
• Simulate phylogeny and trait evolution under various evolutionary models (ecovolve).
• Manipulate phylogenetic trees and ecological community data: convert Newick to Nexus format, prune and merge phylogenetic trees, add branch lengths to your supertrees, community data randomization using one of several null models, and much more...
• Turn species lists into phylogenies (with or without branch lengths) using the included standalone version of phylomatic and phylocom's bladj function.
• Handles large data sets (tested with >10,000 samples/taxa), polytomies, continuous and categorical characters. NEW: detects UNIX/Windows/Mac line-endings in your input files.

(Difference from version 4.1 to 4.2: minor bug fixes, and new options: new2fy and nodesigl)

Obtaining and running Phylocom

The Phylocom distribution consists of C source code, Mac OS X and Windows binaries, manual, and example files. Read the manual for assistance installing and running the software.
