# VRS Python Getting Started Notebook Series | ||
This series of notebooks is intended to be the fastest way to becoming productive with the | ||
[vrs-python](https://github.com/ga4gh/vrs-python) package. The | ||
intent of each notebook in this series is to be an interactive introduction to functionally contained in the vrs-python package. | ||
|
||
A beginning developer level of familiarity with python, jupyter notebooks is assumed in order to run this notebook series. | ||
You should be familiar with installing packages and running commands in your execution environment. | ||
|
||
### Pre-requisites | ||
The following software packages must exist in your execution environment before running these notebooks: | ||
* git | ||
* [email protected] | ||
* make | ||
|
||
### Setup vrs-python | ||
From a terminal window, run the following commands: | ||
* git clone --recurse-submodules https://github.com/ga4gh/vrs-python | ||
* cd vrs-python | ||
* make nbready | ||
* source venv/3.12/bin/activate | ||
* cd notebooks/getting_started | ||
* jupyter notebook notebook_name.ipynb | ||

A beginning developer level of familiarity with python, jupyter notebooks is assumed in | ||
order to run this notebook series. You should be familiar with installing packages and | ||
running commands in your execution environment. | ||
|
||
## Development Environment Setup | ||
|
||
We provide you two options for setting up your development environment: using a Python | ||
[virtual environment](#virtual-environment) or leveraging | ||
[VS Code Dev Containers](#dev-containers) (useful for non-macOS users). | ||
|
||
### Fork the Repo | ||
|
||
Fork the repo at <https://github.com/ga4gh/vrs-python/> and initialize a development | ||
environment. | ||
|
||
```shell | ||
git clone --recurse-submodules [email protected]:YOUR_GITHUB_ID/vrs-python.git | ||
cd vrs-python | ||
``` | ||
|
||
### Virtual Environment | ||
|
||
You must first install [email protected], if not already installed. | ||
|
||
Next, run the following: | ||
|
||
```shell | ||
make nbready | ||
source venv/3.12/bin/activate | ||
``` | ||
|
||
#### Virtual Environment: Selecting the Kernel | ||
|
||
When opening a notebook with this option, click `Select Kernel`, | ||
`Python Environments...`, and select the first option: | ||
`3.12 (Python 3.12.z) venv/3.12/bin/python` | ||
|
||
_Note: Patch version may vary._ | ||
|
||
### Dev Containers | ||
|
||
#### Prerequisites | ||
|
||
For your convenience, this section is copied from the | ||
[VS Code Dev Containers Tutorial](https://code.visualstudio.com/docs/devcontainers/tutorial#_prerequisites). | ||
|
||
* [Install VS Code](https://code.visualstudio.com/download) | ||
|
||
You must be using VS Code to use the Dev Containers. | ||
|
||
* [Install Docker](https://docs.docker.com/get-started/get-docker/) | ||
|
||
Docker is needed to create and manage your containers. | ||
|
||
* Docker Desktop | ||
|
||
Download and install | ||
[Docker Desktop](https://www.docker.com/products/docker-desktop/), or an | ||
[alternative Docker option](https://code.visualstudio.com/remote/advancedcontainers/docker-options), | ||
like Docker on a remote host or Docker compliant CLI. | ||
|
||
* Start Docker | ||
|
||
Run the Docker Desktop application to start Docker. You will know it's running if | ||
you look in the activity tray and see the Docker whale icon. | ||
|
||
Docker might take a few minutes to start. If the whale icon is animated, it is | ||
probably still in the process of starting. You can click on the icon to see the | ||
status. | ||
|
||
* Check Docker | ||
|
||
Once Docker is running, you can confirm that everything is working by opening a new | ||
terminal window and typing the command: | ||
|
||
```shell | ||
docker --version | ||
``` | ||
|
||
* [Install Dev Containers extension](vscode:extension/ms-vscode-remote.remote-containers) | ||
|
||
The Dev Containers extension lets you run Visual Studio Code inside a Docker container. | ||
|
||
[Marketplace Link](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) (if viewing from browser) | ||
|
||
#### Creating the Dev Container | ||
|
||
Open the VS Code Command Palette: Shift + Command + P (Mac) / Ctrl + Shift + P (Windows/Linux) | ||
|
||
Type and select the following inside the Command Palette: `> Dev Containers: Rebuild and Reopen in Container` | ||
|
||
The Dev Container will be created and install the dependencies needed. | ||
|
||
You should see `Dev Container: VRS-Python Notebooks @ desktop-linux` on the bottom left hand corner of VS Code. | ||
|
||
#### Dev Containers: Selecting the Kernel | ||
|
||
When opening a notebook with this option, click `Select Kernel`, | ||
`Python Environments...`, and select the first option: | ||
`Python 3.12.z /usr/local/bin/python` | ||
|
||
_Note: Patch version may vary._ | ||
|
||
## Notebooks | ||
|
||
### 1 Quick Start | ||
|
||
The [Quick Start](1_Quick_Start.ipynb) notebook details how to get started by | ||
setting up access to a SeqRepo *DataProxy* and introduces the user to using an *AlleleTranslator* to convert | ||
the same allele to VRS form from both it's SPDI and HGVS nomenclature forms. | ||
### 2 Exploring the SeqRepo Data Proxy | ||
Sequence references are at the core of many of the operations for converting to and from VRS variant representations. | ||
The [Exploring the SeqRepo Data Proxy](2_Exploring_the_SeqRepo_DataProxy.ipynb) notebook | ||
has a number of useful utility methods for accessing information about sequence references. | ||
### 3 Basic Models | ||
In the [Basic Models](3_Basic_Models.ipynb) notebook, we explore building a VRS *Allele* | ||
from its component parts. The notebook details how to add VRS identifiers to the identifiable components of the *Allele*. | ||
### 4 Exploring the Allele Translator | ||
The current implementation of vrs-python facilitates transformation of variants | ||
in a number of different variant nomenclatures (SPDI, HGVS, gnomAD and Beacon) to VRS form. In the | ||
[Exploring the Allele Translator](4_Exploring_the_AlleleTranslator.ipynb) notebook, | ||
we show how to transform basic variants to VRS, and in some cases, back to the original nomenclature of the variant. | ||
### 5 Exploring the CNV Translator | ||
The final notebook of this series, | ||
[Exploring the CNV Translator](5_Exploring_the_CnvTranslator.ipynb) details transformations | ||
of various forms of copy number variation to their VRS representations. |
