I tried to export the DAPI channel of a certain level of a mrxs image with QuPath to do image registration.
There are 5 channels in this mrxs image. I didn’t know where to find them and how to only export the Dapi channel in Qupath. Besides, I can not properly open it in the Qupath. It lacks some key data like pyramid. But it works fine with 3DHISTECH Case Viewer, which can not do the export sadly.
I also tried openslide.read_region to get the level of the mrxs image. But the return image was wired. It has large white space. No matter which level I try to read, it only returns the image with the smallest level and a large white area.
