Thanks to the work of João Couto, Suite2p now reads *.sbx files. I just processed some of our data and it works nicely. You can download Suite2p from here.
Some of the metadata are currently missing, as they are stored in a Matlab’s object that is not easily read in Python, but I will be working with João to make those, including the NLW mesoscope metadata, available as well soon. João also wrote a stand alone sbxviewer to quickly explore your data.
