levels in mask images

[codeskings]

Dears, thank you for your continuous support. When I was exploring the matching levels between the slides and corresponding masks, I noticed that the number of levels in the ground masks is always 1, shouldn't it contain more levels? especially that we convert the tiff files to pyramidal prior to starting the experiments?

So can you help how can I found the ground truth mask of level 1 and level 2 of WSI?

your help is really apperciated.
