runRMINCTestbed() failing

[lgazdzin]

I've just installed RMINC into R version 4.4.0. runRMINCTestbed() fails in several places with what looks to be a python version issue. I've tried installing python2.7 and pointing the volume_from_labels_only python script to it, but then it can't find python-stuffs and fails again. I've also tried pointing it to my Homebrew installation of python2.7, but that fails for other reasons. It also looks like the testbed terminates early, presumably because it hits to many errors.

Is this going to be a problem with regular RMINC use or is this unique to the testing sets? Is there an easy fix for this?

Thanks!

Here is the output to where this first occurs and the last bit of testing before it terminates early:

Technically, this is a failure of volumes_from_labels_only, a script from minc-stuffs:
https://github.com/Mouse-Imaging-Centre/minc-stuffs/blob/main/python/volumes_from_labels_only

I have confirmed volumes_from_labels_only works in python3.10 with properly installed minc-toolkit-v2 and pyminc
