Description:

Data Visualization Interfaces in Python With Dash

The purpose of this application is to visualize the pipeline of Phylotree and to simplify its use.

https://github.com/tahiri-lab/phylogeography-algo

The project can be used in two ways:

1. Using the filesystem to store the files and results
2. Using a database to store the files and results

The first option is the default option. If you want to use the database, you need to change the .env file. See the section "Setting up the program" for more details.

Getting started

Installing:

• First the programm need to be downloaded with Github(git clone command).

git clone https://github.com/tahiri-lab/iPhylogeo

To download the project simply type one of the command above in a terminal.

• You can also download the zip file with the Github link above.

How to use?

Prerequisites,library etc.

Before using this program make sure that you have installed all the necessary libraries for it to work properly. First, you need to install the aPhyloGeo package. Depending on your OS, the specific commands will be slightly diffrent. Fof a linux based system, you can use the following commands:

1. git clone https://github.com/tahiri-lab/aPhylogeo
2. If you do not have virtualenv installed, run python3 -m pip install --user virtualenv
3. Create a new virtual environment (venv) in your terminal using python3 -m venv venv.
4. Still in the terminal, enter the new venv using source venv/bin/activate.

For a windows based system, you can use the following commands:

1. git clone https://github.com/tahiri-lab/aPhylogeo
2. If you do not have virtualenv installed, run python3 -m pip install --user virtualenv
3. Create a new virtual environment (venv) in your terminal using python3 -m venv venv.
4. Still in the terminal, activate the new venv using venv/Scripts/activate.

N.B. You'll need Microsoft C++ Build Tools to build some of the requirements, you can find it here: https://visualstudio.microsoft.com/visual-cpp-build-tools/ . Make sure to include the C++ build tools.

Then you can install the other requirements. Make sure you are using the same venv as above. Make sure you are in the iPhyloGeo directory. Then run the following commands :

pip install -r requirements.txt
npm install

Finally, if want to run the programm with a database, you need to install docker. You can find the installation guide here : https://docs.docker.com/get-docker/

• Folder apps: template for each web page
• Folder assets: images utilised in template and css file

Setting up the programm

• To set up the programm, you need to change the .env file with your own data. Here is an example of the .env file if you want to run the programm locally :

APP_ENV='dev'
HOST='local'
MONGO_URI=
DB_NAME=
URL='http://localhost'
PORT='8050'

• If you want to run the programm with a database, you need to change the .env. For example :

APP_ENV='dev'
HOST='server'
MONGO_URI='mongodb://localhost:27017'
DB_NAME='iPhyloGeo'
URL='http://localhost'
PORT='8050'

-If you wish for the email address function to operate correctly, you need to generate a "password.env" file within the directory path "iPhyloGeo\apps\pages\results\password.env" with the following format:

GMAIL_PASSWORD=(insert application password of [email protected] here or the e-mail you want to use).

Running

• To run the programm locally, you can use the following command :

npm start

• To run the programm with a database, you need to run the following commands :

docker compose up
npm start

Using the cronJob

If the database is deployed on a linux server, we've included a script to delete the files that are older than 14 days. To do so, you need to create a cronjob. To create a cron job, you can use the cronjob as a template. For exemple create a file named cronjob and add the following line:

00 00 * * * /home/local/USHERBROOKE/belm1207/miniconda3/envs/geo/bin/python /home/local/USHERBROOKE/belm1207/iPhyloGeo/scripts/delete_files.py >> /home/local/USHERBROOKE/belm1207/iPhyloGeo/scripts/cron.log 2>&1

To create the cronjob with the file, you can use the following command:

crontab /home/local/USHERBROOKE/belm1207/iPhyloGeo/scripts/cronjob

This will run the script every day at 00:00 am.

1. The first element of the cronjob is the time. Usefull tools
2. The second element is the path of the python executable. In this case, we use geo environment from conda
3. The third element is the full path of the script file
4. The fourth element is the full path of the log file. This is optional, but it is a good practice to log the output of the script

If you want to see the list of cronjobs, you can use the following command:

crontab -l

How to generate CSS file?

Understanding the structure of the project

• The project use SCSS files witch need to be created in the styles folder.

apps/assets/styles/your_file.scss

• Dash dosen't use SCSS files directly, so you need to generate a CSS file from the SCSS file. To do so, you need to include it in the Gruntfile.js file.

./Gruntfile.js

• In the Gruntfile.js file, you need to add the following code in the dist section. the desire output : the SCSS file location

The CSS files need to be generated in the assets folder, otherwise it won't work

 [...]

 dist: {
                files: {
                    'apps/assets/your_file.css': 'apps/assets/styles/your_file.scss'
                }
 [...]

• In the Gruntfile.js file, you also need to add the following code in the watch/sass/files section. the desire output

The watch section is necessary to regenerate the CSS file when is detected change in the SCSS files, it will also regenerate all CSS files on npm start

 [...]
        watch: {
            sass: {
                files: [
                    'apps/assets/your_file.css'
                ],
            }
        }
  [...]
