PiezoDN Limiter, QTR-Linearize-Quad doesn't work!

Hi there,

Just limiting for alt processes, and created the txt file with a PIEZOGRAPHY_CURVE_ADJUSTMENT tool.
I dragged this txt file and PiezoDN-master.quad file onto QTR-Linearize-Quad, but this doesn’t create any quad files at all. My OS is Big Sur and using QTR v2.8.0.

Is this a OS’s matter?

Make sure you do this on the desktop so you have read/write access to the files you are working with.


Thanks Walker,

I just re-confirmed the read/write access but it’s been set so.
Catalina works but Big Sur doesn’t…

please share a video or screenshots.


Here is the video.

And attached the .quad and .txt file I used.

PiezoDN-Master.quad (8.7 KB)
Cyano1.txt (2.6 KB)

It worked for me on the desktop . . .

PiezoDN-Master-lin.quad (8.8 KB)

Maybe you have iCloud desktop?


No, I am not using iClould desktop…
So this might be happened on my mac only.
