Many groups use tedana for multi-echo fMRI data denoising. The code was opaque and brittle in ways that frustrated both users and developers. We have finally released a major refactor that shouldn't affect results, but will make the results more understandable and will make it easier for current and future developers to innovate. A longer summary of the changes is here https://app.tinyletter.com/#!/messages/10188201/report There's still a lot more that can be done, but this has been a huge group effort with @tsalo @emdupre @dowdlelt @KirstieJane & many others not on mastodon.
