Hi, Sharon,
First of all, thank you and your team for this wonderful workflow. My PhD thesis is a morphometric study on rats with Alzheimer's disease and using QUINT workflow in my study was very useful. However, I would like to ask you about a few things that are on my mind. Can I accept the Reference Region Area information given in the Nutil output report as a morphometric area? My goal is to get volumetric results from this data. For this, I will use the stereology method in my study, but I wonder if this is correct.  For example, if we talk according to the table below; can I consider the cortex area as 4772968 pixels? Also, even if I convert units from pixels to mm² during nutil quantifier, the result is still 4772968. What should I do in this case?

Region name    Region pixels    Region area    Area unit
Cortex    4772968    4.772.967.600.046    pixels
Fibretracts    1755011    1.755.010.611.384    pixels
Hippo    1031737    1.031.736.514.834    pixels
Olfactory    3649652    3.649.652.441.756    pixels

Best regards..
