supermat: Build PHYLIP supermatrix and RAxML partition file using aligned FASTA or PHYLIP files.

Description

Build PHYLIP supermatrix and create RAxML partition file using aligned fasta or phylip files.

Usage

supermat(infiles, outfile = "supermat.out.phy",
         partition.file = "gene_partition.txt")

Arguments

infiles

a character string vector for phylip or aligned fasta file.

outfile

the name of the PHYLIP supermatrix

partition.file

partition data summary describing the genes.

Value

A list containing: (1)supermat.dat:a list containing all the data frames read by read.phylip or read.fasta (2)res.super.dat: a data frame containing the sequences and the names (3)partition.dat: summary for all the fasta or phylip files (4)partition.dat.vector: character string vector for the partition file for RAxML

Details

Supermatrix here means a phylip file with combined aligned sequences. The missing sequences should be replaced with either "?" or "-".
