This is awesome. Thanks for your reply. So, one more for you.. just to clarify.. In your command example: 8309_016.2B_psm4 should be with the prefix _psm4? Is it true or just mistype? Do I need to pass the tiff file through some filter to remove colors or something like that? The examples you shared in your tar.gz file, which are awesome, there are in gray scales and not sure about the resolution. Is there some preparation of the image in order to improve output?
Thanks again!
