We have a light sheet data set of 129GB. We successfully create the xml file and open the data with BigStitcher. We would then like to resave the stitched dataset as Tiff. But when we right click in the tile list in Big Stitcher and select Resave as compressed TIFF, we are getting an error message "File saving error IOException. We have tried to directly save as compressed TIFF or to first save as h5 then resave as compressed tiff but we get the same error in both cases. What are we doing wrong?
