Hi,

Is anything other than specifying "w8" in TIFFOpen() required to successfully create a BigTIFF file?

When my dataset is < 4GB and I open with "w" and write the data, I can view the image just fine.

When it is > 4GB and I use "w8" to open, all else the same, then the resulting file cannot be opened by any of the image viewers I can find that are said to support BigTIFF (IMARIS, Nikon Elements, FIJI/BioFormats, and VeryLargeImageViewer)

Is there some other header fields I must add?

Thanks,

-Paul
