You're welcome!
Combining PTO files is exactly what pto_merge is for.

Seems to work if I do a pass with --linearmatch first, and a second

Thanks for the idea @GnomeNomad. I guess it makes sense to get at
least the rows taken care of that way...
Right now I'm trying to understand the file structure of the .pto
files to see if it is possible to combine different files (with
different Control points into one.

Any ideas

I don't know anything about scripting this, but does the
--linearmatch
option handle matching images better? That matches image 1-2,
2-3, 3-4,
4-5, etc.
I don't know what it would do when it hit the end of each row. I
suppose
it might try to match images 5 and 6 (end of one row, start of
next).
Not what you want.
Perhaps you could precede these steps by using pto_gen to
generate a
separate PTO file for each row of images, run cpfind's
--linearmatch on
each separate PTO file, then use pto_merge to merge the
resulting PTO
files all into a single project file.
Ideas?
