ScanITD

📦 Installation

ScanITD can be installed using Conda (via the Bioconda channel) or pip.

Via Conda (Bioconda)

To install ScanITD using Conda:

conda install -c bioconda scanitd

Or using the modern bioconda::scanitd specifier:

conda install bioconda::scanitd

Via Pip

ScanITD can also be installed using pip, the Python package installer:

1. Ensure you have Python 3.10 or later installed on your system.

2. Create a virtual environment (recommended):

   python -m venv scanitd_env
   source scanitd_env/bin/activate  # On Windows use `scanitd_env\Scripts\activate`

3. Install ScanITD:

   pip install scanitd
