I have modified the current verison of the JACOP plugin so that it sends
a correlatoin coefficient to the results table when it runs a Pearson
Correlation. Then I run a simple macro that runs a Pearson Correlation
after translating one image with respect to another over an abritrary
size grid. The location of best fit is recorded, and essentially you get
a the x,y translation of the original image with respect to a reference
image. It's a rather slow, ugly hack, but it gets the job done. I'm
happy to share it if it can be of help.
However, this was just a poor man's work around. I agree with some other
comments that it's surprising that other plugins like TurboReg don't
make this kind of info easier to get at. That would be super useful.
Cheers,
Damon
