If you like me are the owner of aging Phase One Pnn/Pnn+ digital back and find your back started to produce more defective (hot, cold) pixels or the whole columns(rows - in native sensor orientation still columns) then you may be interested in this.
Just like the software I had created for Kodak Probacks, IIQRemap utility now exists for Phase One back. It is fully open source and comes with pre-built binaries for macOS and Windows 10 64 It was tested with Kodak sensor based Pnn/Pnn+ backs. For Pnn+ backs with Sensor+ and all IQnnn backs with Sensor+, the latest version 1.5 adds support for dual remap (extra complication that calibration file needs to be dual part one generated from standard and Sensor+ raw files). This last version was tested with IQ1xx backs, it will most likely work with IQ2xx backs but I cannot say whether it will work with IQ3xx/IQ4xx - have not really checked their calibration file format and layout (backup calibration file can easily be saved by FW update utility so it should be safe to try anyway).
I know that Phase One still will do those remaps if you send them your digital back or occasionally they can do it from the raw file. But this tool puts the power into your own hands (and saves you a bit of money and hassle producing the "correct" raw files that Phase One will accept).
Suffice to say it took me an hour to do comprehensive remap of my P25+ (from a few carefully shot dark frames) and before that I spent 2 days arguing about the raw files with Phase One (as none of them were apparently suitable even though those lines of pixels could clearly be seen when pulling out shadows).
It was used by a few people already to remap their backs so hopefully it will be helpful to someone here as well.
