Unable to install with python 3 pip

Here is a copy of the error code:

(base) aaron@aaron-VirtualBox:/media/sf_Ubuntu_files$  pip3 install meica
Collecting meica

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://pypi.org/simple/meica/

It appears that the url does not work? What should I do? I'd prefer to install the python 3 version if I can.

Hi @Aaronearlerichardson,

Is there a particular reason you are trying to install meica rather than tedana? This repository is considered outdated and is no longer maintained. Development has continued on tedana, the core multiecho/ICA processing code.

You can clone the repository and use it in a somewhat similar fashion. See here for the tedana code, https://github.com/ME-ICA/tedana and here https://tedana.readthedocs.io/en/latest/ for the tedana docs/installation guidelines etc.

The idea is that you would handle preprocessing of the echoes, and then pass the data through to tedana for optimal combination and denoising. This is contrast to the previous usage of MEICA, which performed a number of steps for you. If you would prefer to have the processing done in AFNI, as it was for MEICA, example 12 (and a few others) in the afni_proc.py help may be useful: https://afni.nimh.nih.gov/pub/dist/doc/program_help/afni_proc.py.html

Let me know if this makes sense. If you run into some problems, check the tedana issues or neurostars.org for the tedana flag - someone may have solved that problem previously.
