# locigenesis
locigenesis is a tool that generates a human T-cell receptor (TCR), runs
it through a sequence reader simulation tool and extracts CDR3.
The goal of this project is to generate both HVR sequences with and
without sequencing errors, in order to create datasets for a Machine
Learning algorithm.
## Technologies
- [immuneSIM](https://github.com/GreiffLab/immuneSIM/): in silico
generation of human and mouse BCR and TCR repertoires
- [CuReSim](http://www.pegase-biosciences.com/curesim-a-customized-read-simulator/):
read simulator that mimics Ion Torrent sequencing
## Installation
This project uses [Nix](https://nixos.org/) to ensure reproducible
builds.
1. Install Nix (compatible with MacOS, Linux and
[WSL](https://docs.microsoft.com/en-us/windows/wsl/about)):
```bash
curl -L https://nixos.org/nix/install | sh
```
2. Clone the repository:
```bash
git clone https://git.coolneng.duckdns.org/coolneng/locigenesis
```
3. Change the working directory to the project:
```bash
cd locigenesis
```
4. Enter the nix-shell:
```bash
nix-shell
```
After running these commands, you will find yourself in a shell that
contains all the needed dependencies.
## Usage
An execution script that accepts 2 parameters is provided, the following
command invokes it:
```bash
./generation.sh <number of sequences> <number of reads>
```
- \<number of sequences\>: an integer that specifies the number of
different sequences to generate
- \<number of reads\>: an integer that specifies the number of reads
to perform on each sequence
The script will generate 2 files under the data directory:
------------------- -----------------------------------------------------------------
HVR.fastq Contains the original CDR3 sequence
CuReSim-HVR.fastq Contains CDR3 after the read simulation, with sequencing errors
------------------- -----------------------------------------------------------------
