When running the GLCM from snappy against a large geotiff file of 4.2 GB, we get this error , Java max ram size was also changed to 28 GB on my PC.
Any comment plz!
You’re hitting the maximum size of the TIFF file-format, use BigTIFF instead.

Thanks for ur reply. I get the error when I change to bigtiff. 
And I am wondering whether bigtiff will reduce the quality of the image or we might miss some metadata info by doing so.
glcmOp().glcm(product,“myband”,
myDictionary,“BigTIFF”)
By the way, the input is still in geotiff (over 4 Gb), but the output is stored in bigtiff .However, it doesn’t accept it!
As format name you should use GeoTIFF-BigTIFF
In WriteProduct - where to find allowed formatName you find a python scripts which prints all format names and the default extensions of the product reader and writer.
