error after install with bioconda

[fwhelan]

Hi oxygen311,

I've installed parebricks with conda install -c conda-forge -c bioconda PaReBrick. When I try to run the provided example code, I get the following error; any thoughts (e.g. is there a required version of bg)?

$ parebrick -t tree.nwk -b maf2synteny-output -l labels.csv

Hi @fwhelan!

Sorry for the late response.

One of PaReBrick dependencies (bg) works only with python <= 3.8. I don't see a quick fix to support a newer version and can only suggest using it with a separate conda python 3.8 environment.

You can try:

Step 1: Create the Conda Environment

First, you'll need to create a new Conda environment with Python 3.8.

conda create -n parebrick_env python=3.8

This command creates a new environment named parebrick_env with Python 3.8 installed.

Step 2: Activate the Environment

Activate the newly created environment.

conda activate parebrick_env

Step 3: Install PaReBrick

Now that your environment is active, install the PaReBrick package using conda or pip.

pip install PaReBrick

or

conda install -c conda-forge -c bioconda PaReBrick

Step 4: Deactivate the Environment (Optional)

When you're done working, you can deactivate the environment by running:

conda deactivate
