Tree2gd

Project description

Tree2gd on the Python Package Index (PyPI) Tree2gd Python Version (PyPI)

Tree2gd

Tree2GD provides an integrated pipeline to identify WGD events, with friendful commands in one-step or multiple steps, with smart quality control in custom dataset, with multithreading design costing low time, with well performance in detect WGD signals, and with advanced visualization of GDs and Ks peaks.

Python Requirements

We currently recommend using Python 3.8 from http://www.python.org Tree2GD is currently supported and tested on the following Python implementations:

Installing by sudo apt-get install python3-pip or with get-pip.py using

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py

R Requirements

In order to complete the final drawing result display,We currently recommend using R>=v4.0.0 from https://www.r-project.org

Installation

Installation From Pypi

You can quickly install Tree2gd through the following command, and automatically install the python packages it depends on by run:

pip3 install Tree2gd [--user]  #You may need the --user parameter if you do not have administrator rights

If you need to use a specific python3 path to install and use Tree2gd, you can replace the above pip3 with /THE/PATH/OF/YOUR/PYTHON3 -m pip

Installation From Source

You can download and decompress our source code, or fetch it using git. Now change directory to the Tree2gd source code folder and run:

python3 setup.py build
python3 setup.py test
python3 setup.py install [--user] #You may need the --user parameter if you do not have administrator rights

Testing

After the installation is successful, the main program command Tree2gd and test command Tree2gd_test will be added to your system. You can first check whether Tree2gd is installed successfully by running the following command:

$ Tree2gd -h

If the system feeds back its corresponding parameter description, congratulations on the correct installation of Tree2gd to your system! Next, we strongly recommend that you run Tree2gd_test to use the data we have prepared for a quick and complete Tree2gd test, because you can get the following benefits:

1.Check whether the pre-compiled version of the software we use by default is suitable for your system, and replace the unavailable ones with the configuration file (see the following instructions for configuration).

2.When using for the first time, in the final drawing part, we will spend a few minutes to install several dependent packages in R. After that, the formal use will be faster and more convenient.

3.After the user modifies the configuration file, you can add own new settings through the -config parameter of the command to test, and quickly detect that the new configuration can run successfully.

The Tree2gd_test command will run the complete analysis process with the fastest parameter settings. It only contains two optional parameters command:

$ Tree2gd_test [-t] [--config]
   -t [int] sets the number of threads for testing (default: 1)
   --config [str] uses the configuration given by the user File for testing (verify availability of custom configuration)

In the case of 4 cpus, it takes about 5 minutes to complete a round of testing (the first run will take some extra time to download and install the R package). After successful operation, it will generate a folder in the current directory``./Tree2gd_test_out``, You can check it (especially the final drawing result Tree2GD.result.pdf in step6) to fully verify the running effect of the software.

Running

You can complete all WGD analysis only with the simplest commands below and get a perfect drawing display:

$ Tree2gd -i input_dir -tree phytree.nwk

Among them, phytree.nwk is the species evolution tree in newick format.

The input_dir folder contains all the corresponding protein sequences (default postfix .pep) and cds sequences (default postfix .cds) of each species contained in phytree.nwk by fasta format.

In addition, you can add the following optional parameters to make the program run faster and better (especially when using multi-core operation):

-t t Thread num.default:1
-o outputdir The output dir.default:./output
--step step_num_str
 Which steps you need.default:123456(Choose from numbers: such as ‘234’)
--log logfile log file name,or log will print on stdout
--config config_file
 config.ini configuration file, leave it blank to run with default parameters and the program’s own software version.
--debug The log file will contain the output of each software itself, which is convenient for finding errors (-log is required)
--only_script Only generate scripts, not run automatically.
--cds2tree Use cds sequence to construct gene tree.

Detailed parameter configuration file : config.ini

There are many softwares in the Tree2gd process. The pre-compiled versions of the programs are already used by default. At the same time, these softwares have many parameters that can be adjusted to achieve the best results.

So we used the config.ini file to summarize these settings, input it to the program through the -config parameter, and call the configuration in the corresponding program.

! note! Any item in this file is optional, users only need to add the lines they need in the corresponding section
