Getting Started

Install the module with:

npm install molphylo

Usage

Require module:

var molphylo = require('./MolPhylo.js')

ensure executables are in your $PATH

Get fastA Sequences

Sequence Accession Numbers are collected from the commandline separated by a space (not a comma)

Node uses NCBI e-utilities to download sequences in fastA format:

molphylo.fasta(process.argv, molphylo.renameFile)

Basic usage: node index.js inputfile list of space separated accession numbers

node index.js NM_001028053.2 AF032112.1

Get Sequence information in JSON format

Sequence Accession Numbers are collected as per fastA sequences above using the genbank_json method:

molphylo.genbank_json(process.argv)

Basic usage: node index.js inputfile list of space separated accession numbers

node index.js NM_001028053.2 AF032112.1

PhyML

Download PhyML using this command

molphylo.getphyml()

Run phyml program

molphylo.Ml(process.argv[2], process.argv)

Basic usage: node index.js inputfile insert any flags (from flags below)

node index.js example_PhyML.phy -q -d aa -m JTT -c 4 -a e

Primer3

collect input file name

var inPut = process.argv[2]

Run Primer3 program

molphylo.primer3_run(inPut, process.argv, molphylo.primers)

Basic usage: node index.js filename -flags (from table below)

node index.js example_p3 -format_output

MUSCLE

Download muscle executable

molphylo.getmuscle()

get Path for output

var outFile = './Output/Musle_Result.aln

Run MUSCLE program

molphylo.run_muscle(process.argv[2], outFile, process.argv, molphylo.muscle)

Basic usage: node index.js inputfile insert any flags preceeded by '-' sign and seperated by a space (from flags below)

node index.js DNA.fasta -msf -html

Clustal Omega

Download Clustal Omega executable

molphylo.getclustal()

get Path for output

var outFile = './Output/Clustal_Result.aln

Run Clustal Omega program

molphylo.run_clustal(process.argv[2], outFile, process.argv, molphylo.clustal)

Basic usage: node index.js inputfile insert any flags preceeded by '--' sign and seperated by a space

node index.js DNA.fasta --outfmt phy

Pipes

Commands can be chained in series to pipe data between applications:

var shell = require('molphylo_pipes');

pipes dir contains the module for piping as well as example files. To execute example:

node pipe_example.js

pipe_example.js pipes the output from an NCBI fetch API call into the alignment software MUSCLE and aligns the DNA using default settings

Note: must have MUSCLE in $PATH for pipe example

Testing

MolPhylo was successfully tested on: 1. Microsoft Windows 7 Enterprise ver.6.1 2. MacOSX El Capitan ver.10.11.5 3. Linux Ubuntu 64-bit ver.14.04 LTS

To perform tests:

npm test

To ensure all developmental dependencies are installed:

npm install --dev

Note: if you get a permission error when runnning tests you may have to chmod mocha

chmod 0777 mocha
