  • Problem installing `bluepy` from the repo.

    Problem installing `bluepy` from the repo.

    Problem: for my machine (machine spec mentioned below), installing requirements on this repo, as given in requirements.txt throws the following error.

    error: legacy-install-failure
    
    × Encountered error while trying to install package.
    ╰─> bluepy
    
    note: This is an issue with the package mentioned above, not pip.
    hint: See above for output from the failure.
    

    This error is in context with mention of bluepy in requirements.txt.

    Machine Specs:

    1. miniconda venv for python 3.9.12 running on MacOS Monterey; CPU: Apple M2.
    2. miniconda venv for python 3.10.4 running on Ubuntu Jammy Jellyfish; CPU: AMD Ryzen.

    Interesting Note: I don't find bluepy being directly imported in the code on the master or the CDT-app-gui branch.

    Proposed Solution:

    1. Remove bluepy from requirements.txt

    Note: This is not a problem with installing PyTranskit itself. It installs pretty gracefully through pip.

    Changed filter to filter_name

    In the radoncdt.py file passing the option filter was not working since scikit-image expects the key filter_name.

    Issue when setting forward('rm_edge = True')

    This possibly just needs an edit to reduce the size of the reference signal array alongside the reduction in size of the signal with removed edges.
