Click here for the live demo of GrapeTree!
GrapeTree is an integral part of EnteroBase and we advise that you use GrapeTree through EnteroBase for the best results. However, many people have asked for a stand-alone GrapeTree version that they could use offline or integrate into the other applications.
The stand-alone version emulates the EnteroBase version through a lightweight webserver running on your local computer. You will be interacting with the program as you would in EnteroBase; through a web browser. We recommend Google Chrome for best results.
For detailed help please see: http://enterobase.readthedocs.io/en/latest/grapetree/grapetree-about.html
For a formal description, please see the preprint: https://www.biorxiv.org/content/early/2017/11/09/216788
There are number of different ways to interact with GrapeTree, for best results install via pip :
pip install grapetree
grapetree
We also have ready-made binaries for download here: https://github.com/achtman-lab/GrapeTree/releases
Running on Mac: Download GrapeTree_mac.zip
You will need to unzip GrapeTree_mac.zip (just double click). Inside there will be an app you can drag into your Applications folder. You may be warned about Security settings, if you right click on the GrapeTree app and then click "Open" it should be fine.
Running on Windows: Download GrapeTree_win.zip
Once downloaded, you will need to untzip GrapeTree_win.zip and then open the extracted folder and run GrapeTree_win.exe. When you run it the first time on windows you might get a prompt about security. On Windows 10, click the small text: "More info", and then the button "Run Anyway".
Running from Source code
GrapeTree requires Python 2.7 and some additional python modules (listed in requirements.txt). The easiest way to install these modules is with pip:
pip install -r requirements.txt
chmod +x binaries/
On Linux or MacOSX you need to make sure the binaries in binaries/ can be executed. To run GrapeTree;
- Navigate to the directory where you installed GrapeTree.
- Run it through python as below.
\GrapeTree>python main.py
* Running on http://127.0.0.1:8000/ (Press CTRL+C to quit)
The program will automatically open your web browser and you will see the GrapeTree Splash Screen. If at anytime you want to restart the page you can visit http://localhost:8000 in your web browser. To view a tree (newick or Nexus) or create a tree from an allele profile, just drag and drop the file into the browser window.
Runtime behaviour can be configured in grapetree/config.py.
Developers may wish to look at the JavaScript documentation (JSDoc).
To run tests, run pytests in the top level directory.
pytest
usage: MSTrees.py [-h] --profile PROFILE [--method METHOD]
[--matrix MATRIX_TYPE] [--recraft]
[--missing HANDLE_MISSING] [--wgMLST]
[--heuristic HEURISTIC] [--n_proc N_PROC] [--check]
Parameters for command line version of GrapeTree.
You can drag the Newick output into the web interface.
optional arguments:
-h, --help show this help message and exit
--profile PROFILE, -p PROFILE
A file contains either MLST / SNP profiles or multile aligned sequences in fasta format.
--method METHOD, -m METHOD
backend algorithms to call. Allowed values are "MSTreeV2" [default], "MSTree" and "NJ"
--matrix MATRIX_TYPE, -x MATRIX_TYPE
Either "symmetric" [default for MSTree and NJ]
or "asymmetric" [default for MSTreeV2].
--recraft, -r Allows local branch recrafting after tree construction. Default in MSTreeV2.
--missing HANDLE_MISSING, -y HANDLE_MISSING
Alternative ways of handling missing data.
0: missing data are ignored in pairwise comparisons [default].
1: Columns that have missing data are ignored in the whole analysis.
2: missing data are treated as a special value (allele).
3: Naive counting of absolute differences between profiles.
--wgMLST, -w Use when > 20 % of values in the input are missing.
--heuristic HEURISTIC, -t HEURISTIC
Tiebreak rules between co-optimal edges. Only used in MSTree [default: eBurst] and MSTreeV2 [default: harmonic]
--n_proc N_PROC, -n N_PROC
Number of processes. Default: 5.
--check, -c Do not calculate the tree but only show the expected time/memory consumption.
