Your image has a tiny numeric range, it varies between -0.0013 and +0.0083. The sliders in nip2 will scale an image by up to 256, but that's not enough to make anything visible.

If you click on the cogs to the left of the display control bar, there's an extra menu. Select "scale" and it'll search the part of the image that's visible and pick a scale and offset to make that area 0 - 255. If I do that I can see a rather nice image of a ball of cells, or something like that. Pretty!

Is the numeric value significant? If not, I'd just scale it up a bit. If you have your image loaded as A1, type A1 * 20000 in the text box to make something that's a bit easier to see.

You probably need to give it a hint on how to convert your image for display.

Double-click on the thumbnail in the main nip2 window to open an image view, then select View / Display Control. Move the two sliders about and you should be able to get something to appear.

Sure, upload a sample image somewhere, I'd be happy to have a look.
