Installation

Prerequisites

NEMAR CLI requires Bun runtime (v1.0+).

Install Bun

# macOS, Linux, WSL
curl -fsSL https://bun.sh/install | bash

# Windows (PowerShell)
powershell -c "irm bun.sh/install.ps1 | iex"

# Homebrew
brew install oven-sh/bun/bun

For Dataset Operations

• DataLad (v1.0+) - For dataset upload/download
• git-annex (v10+) - Large file management
• Deno (v1.40+) - For BIDS validation

Install NEMAR CLI

Using Bun

# Install globally
bun install -g nemar-cli

# Or run directly without installing
bunx nemar-cli --help

From Source

git clone https://github.com/nemarOrg/nemar-cli.git
cd nemar-cli
bun install
bun link

Install Optional Dependencies

macOS

# Using Homebrew
brew install git-annex datalad deno

# Or using conda
conda install -c conda-forge datalad git-annex

Linux (Ubuntu/Debian)

# Install git-annex
sudo apt-get update
sudo apt-get install -y git-annex

# Install DataLad
pip install datalad

# Install Deno
curl -fsSL https://deno.land/install.sh | sh

Windows (WSL)

We recommend using Windows Subsystem for Linux (WSL) for the best experience:

# In WSL Ubuntu
sudo apt-get install git-annex
pip install datalad

Verify Installation

# Check CLI version
nemar --version

# Check Bun
bun --version

# Check optional dependencies (for dataset operations)
git --version
git-annex version
datalad --version
deno --version

Troubleshooting

”command not found: nemar”

Ensure Bun’s bin directory is in your PATH:

# Add to ~/.bashrc or ~/.zshrc
export PATH="$HOME/.bun/bin:$PATH"
