I've been searching for this info, pardon me if someone has already answered it somewhere else.
If I want to create custom targets for i1Profiler (I'm on v1.3.2), like how SergeyT did:
http://www.luminous-landscape.com/forum/index.php?topic=65703.msg525894#msg525894 combine 1000+ color patches auto generated by i1Profiler with the max number of neutrals and slightly-off-neutrals from a 5837 target also auto generated by i1Profiler, how do I go about manipulating the pxf files? I tried opening it up in a text editor and got lost. Am I supposed to/only allowed to modify it from there? I also want to pay around adding my own custom patches to it, just to see how that affects the profile generation in terms of accuracy, smoothness etc. I know I read about others doing so to.
I appreciate any help on this! Thank you.
