 # QuBaLab

 This is a Python package for exploring quantitative bioimage analysis... *especially* (but not exclusively) in combination with QuPath (https://qupath.github.io/).
 
 The name comes from **Quantitative Bioimage Analysis Laboratory**. This is chosen to be reminiscent of QuPath (*Quantitative Pathology*), but recognizes that neither is really restricted to pathology.
