QTR-Quadtone RIP

Folks, I'm still having issues with this.  My original post was 
somewhat unclear, hopefully this will clear it up...

Basically, I'm following the directions on curve linearization in the 
Eye-One-ReadMe.pdf contained in the QuadToneRIP\Eye-One folder.

I have an Eye-One Photo LT.  I used Gretag-Macbeth's 
ProfileMaker "MeasureTool" (demo version) to open, and then spot-
measure, the QTR-21x4-random file.

Once that was done, I saved the resulting .txt file and dragged it 
onto the QTR-Linearize-Data.exe program to create a graph with 51 
readings.  The L data graph is nice and straight until it gets to 
about 60.00, so linearization is needed; this is where I get lost.  
The directions for linearizing are detailed in the .pdf as follows:

"The Linearization process is simply creating a correction curve 
using the above data to straighten the L data graph. To use this 
feature, simply create the ink description file, doing the 
partitioning. The GRAY_HIGHLIGHT and GRAY_SHADOW fields can be 
approximated at 4 and 8 respectively. Make the quad curve and print 
out the Step-21-gray stepwedge, and measure as above. The last line 
has the linearization info. Triple-click on it, Copy the whole line 
and Paste it to the bottom of the ink description file. Re-process 
the ink file with Drop-Quad-Profile."

I'm in the dark from "...simply create the ink description file..."

That is:
1) What is meant by "...simply create the ink description file, doing 
the partitioning."?

2) "The GRAY_HIGHLIGHT and GRAY_SHADOW fields can be approximated at 
4 and 8 respectively..."  --> Which tab in QTR's Curve Creator?

3) "Make the quad curve and print out the Step-21-gray stepwedge, and 
measure as above."  --> Which quad curve?  Do I print out the Step-21-
gray stepwedge even though I worked with the larger (51 step) file?

Thanks, appreaciate any input-
Jens
