Hi, I am currently trying to export huge numbers of png slice images from QuickNII, up to fifty thousand at a time. 
One problem I am having is it seems that having to export .flat files, which I don't need for my purpose, slows down the export process immensely as they are much larger than the corresponding png files. Is there a way I can disable the exporting of the .flat files and only export pngs?
Any help would be greatly appreciated
