I worked around this by creating an empty blacklist containing just chrEBV.

Hi @mp15

Thank you for raising that issue.
Did you install Spectre directly from pip or did you clone the repository and install it locally with pip?
The latest version on GitHub has a fix that should address this issue (issue: #11, Commit: eb78bfe)

Install Spectre with the latest changes:

pip install build
git clone https://github.com/fritzsedlazeck/Spectre.git
cd ./Spectre
python3 -m build
pip install dist/spectre-cnv-<VERSION>.tar.gz # replace <VERSION> with e.g. 0.2.0

Please let me know if that helped.

Cheers,
Philippe

This was indeed from pip, was hoping that was the stable version :). You are indeed correct I have tested and the version in git resolves this issue.
