Problem with image fusing and quick display

[MaxRum]

Hi, I encountered a Problem using BigStitcher as well as MultiView Recon.
As soon as I want to do a preview of the stitched image, it seems ImageJ (or FIJI) is stuck in an endless loop of loading and opening the data files (raw tiff images) without ever displaying them. I cannot perform fusion of the images as the same behavior occurs.
I am running FIJI on a windows based machine with sufficient memory for the task at hand (256 GB).
I am running FIJI v.1.54f
Please advise where my error might be?

Hi, all preview functions do not work well with non-blocked data formats (N5/HDF5/ZARR). Could you please try re-saving the project first?
