Hi all,

I’m trying to create a 3D image out of a series of histological sections. I have a .czi file of each slide which I separated into the individual slices and saved as different formats (.tif, .png., .jpeg., .czi) to try to import them into Slicer. Problem is, I can load them without issue the normal way but when I try to load them unchecking “Single File” under “Show Options” (as it’s specified on the tutorial) it fails with a generic error message and I’m at my wits end on what to do.

This is the error I get - Error: Loading H:/Slides/Slide scans/Cestoplana-03/Cestoplana-03\_s01.tif - load failed.

Could anyone give me a hand with this?

Thank you in advance.
