Dave,
PatchTool has the Extract-Target-from-Image function that lets you get even 8
or 16bit LAB data from a (8 or 16bit) TIF image instantly. Especially if you
have a target-type scanned or photographed image with hundreds or thousands of
patches that speeds up your work infinitely. After extraction you can export a
CGATS type file for further processing.
Best,
Joe

Thank u so much for all your ideas. I was going to do it manually but I
though 140 patches!!! But that's fine. I usually use patchtool from
babelcolor and I manually type all Lab values. I could convert 140 patches in
one sec with Patchtool but is $125. Scanin is doing the hard stuff.
Thanks again,
Dave

I am trying to create a cgats file from an AdobeRGB tiff image of a

If you're just looking for L*a*b* textual data, and you're starting with
textual RGB data, you can use Argyll's xicclu. There's enough patches in the
ColorChecker SG for it to be worth a bit of work with awk / sed / your
favorite text editor to automate it...but there's not so many that you can't
do it manually (perhaps with copy / paste) if that's not your thing.
If you need to create an RGB image of a chart, you can use printtarg to
create a TIFF and then your favorite image editing software to wrangle the
patches into place.
If you need to create a L*a*b* image...I don't _think_ Argyll directly
supports that, though you might be able to do so with cctiff. But you can
certainly do so programmatically with ImageMagick.
Cheers,
