Issues:

The instructions say that the dimension to be extracted (C) must lie along x.  So starting from my
HCN dataset, I need to do a transpose.  So I'll need a script that's just xyz2pipe -x followed by pipe2xyz -y.  I'll name the new files testchn%03.dat.

Then there is the base name, which is the input without the number and the .DAT.  Note: this program requires the extension to be .DAT in caps.

Y_WIDTH_P would then be peak width in ppm for H
Z_WIDTH_P would then be peak width in ppm for N

0.06 for H and 0.6 for N seem tight.  They are more like .12 and 1.2;  Are these half widths? Or are they set smaller than the peaks on purpose?

Y_LINE_WIDTH and Z_LINE_WIDTH are described as lorenzian linewidth in units of ppm for weighting data vectors along the dimension.  I have no idea how to get these numbers, what they mean, or what weighting the algorithm is called upon to do.  The example has 0.25 and 0.8, which are disproportionate to the actual widths and don't make any senze as a peak at half height???   See what's in some real data scripts.   Andy basically uses these numbers.

Strip.com
The first entry is the name of the output file, which is a single file
The numbers aren't used; instead the data is displayed where the coordinate number is strip
number in consecutive order.  the Blank strip enties will also be counted.  (It's set up so that
you could enter the coordinates in the order of the amino acid sequence, leaving out residues
that aren't in the dataset.

The only things that will likely be meaningfull in the strips are the spots centered on the interger coordinate.  A 2D Lorenzian peak is forced.  Other spots off the axis show up, but will be deformed.  The intention is that they would be centered up in another strip.
