Tools for processing SWI/QSM data

Does anyone know of any open-source tools for processing susceptibility-weighted imaging (SWI) or quantitative susceptibility mapping (QSM), preferably in Python or MATLAB? I realize that I’m talking about a broad literature with a lot of different methods, but I haven’t come across any available tools or workflows to use even as a starting point.

two (in my opinion) mature toolkits are STISuite (Matlab: https://people.eecs.berkeley.edu/~chunlei.liu/software.html) or TGV-QSM (Python: http://www.neuroimaging.at/pages/qsm.php)

here is a good overview of all current toolkits:

That is way more than I was expecting. Thank you!

A naive followup question- do you know of any open source SWI processing tools, esp. for segmenting vasculature?
