Units of artificial porous media generated by porespy

[javierpagalo]

Hello
I would like to know, when I generate a porous media using generators.blobs, what's the dimension of every voxel? 1um, 1mm or what?

Waiting for your response.
Thank you.

Hi @javierpagalo. They're dimensionless, i.e. 1 voxel per voxel! Depending on what you do with the image, the unit will appear later on. For instance, if you do network extraction, then you need to provide the unit of your image to the network extraction routine. PoreSpy's SNOW algorithm, for instance, takes voxel_size as an input (a voxel size of 1 indicates 1 meter per voxel):
