GraftM is a pipeline used for identifying and classifying marker gene reads from metagenomic datasets

Project Description
# GraftM
GraftM is a tool for finding genes of interest in metagenomes, metatranscriptomes, and whole genomes.

Using modular gene packages, GraftM will search the provided sequences using hmmsearch (HMMER) and place the identified sequences into a pre-constructed phylogenetic tree. The provides fast, phylogenetically informed community profiles and genome annotations. GraftM provides tools to:
* Create and update custom gene packages to use with GraftM
* Decorate trees, and of course..
* Analyse sequence datasets using these GraftM packages
Head over to the [GraftM page]( for more general information.

### Installation
#### pip installation
GraftM can be installed via pip:
pip install graftm
However, to use all features of GraftM a few extra binary applications are required:
* orfm v. >= 0.2.0 (
* hmmer v. >= 3.1b1 (
* fxtract (
* pplacer v. >= 2.6.32 (
* krona v. >= 2.4 (
* mafft v. >= 7.22 (
* diamond v. >= 0.7.9 (

To create new GraftM packages, you'll also need
* FastTreeMP (

#### Docker images
Versions of graftM on pip now have matching docker images as of GraftM v0.9.2. GraftM docker images are portable containers that contain the graftM code and all its python and non-python dependancies, allowing GraftM to be run on any platform with docker installed. Details on how to download and run a GraftM docker image can be found on the [graftm-docker]( GitHub page or the [docker hub page](

### Manual
A [manual]( is available in the form of the wiki here on GitHub.

### GraftM packages
We have a starter pack of graftM packages available including:

* 16S rRNA packages
* 15 single copy ribosomal protein marker genes
* The methanogenesis marker mcrA

All are available at the [ACE ftp GraftM package database store](

Once you have downloaded the package you want, just decompress it as follows:

tar -xvzf my.tar.gz
And you should be good to go!

### Example: 'graft'
We'll use GraftM to classify a single 16S sequence from GreenGenes. Save the example file as `/tmp/eg.fasta` with the following contents:
Then we can use GraftM's 61% OTU clustered GraftM package to detect and classify this sequence. Running graftM might look something like this:
$ graftM graft --forward /tmp/eg.fasta --graftm_package /path/to/4.01.2013_08_greengenes_61_otus.gpkg/ --output_directory eg.graftm

GraftM 0.9.2

This creates a folder `eg.graftm` which contains the results.

### Example: 'create'

We encourage you to create your own GraftM packages that suit your own analysis
needs (e.g. new genes, more representatives, improved annotation of phylogenetic
trees, etc.). Here we will create a 16S package out from a highly dereplicated
collection provided by GreenGenes. The data here are provided in the
folder of GraftM.
$ graftM create --output /tmp/my.gpkg --sequences 61_otus.fasta --taxonomy 61_otu_taxonomy.txt

GraftM 0.9.5

Then, the output package `/tmp/my.gpkg` can be provided to 'graft'. There are
many optional arguments to 'create' which can be used to modify the process of
making gpkgs.

Happy grafting!
