Additional info:
Attempting to build the gigapan panorama for the attached image.  The four images used to create the crash are those comprising the top of teh tower in the right centre of the shoot.  I think there is not much overlap in these images due to a glitch that probably happened when the tripod was moved 10 or so metres - likely something got bumped and I only find out now that I attempt to stitch the images.

Did you try stitching the images without using the Gigapan import filter/wizard?

Sorry for the confusion - not in the middle of the shoot.  Had setup to take the shoot but one of the other folks with me pointed out it was possible to get in a better location - so the camera was removed from the Gigapan robot and we lugged the gear to a new location.  In doing so I think the field of view setting on the robot didn't match the focal length the images were shot at.  My best guess is there's sufficient overlap in the images to make columns but possibly not to make rows.  Oops

I think I imported all 144 images into a single group and the result was every image was linked to every other image?

Err.. I meant just the four images that you were talking about trying to stitch.

(sorry about the delay in my reply)

Thanks for the feedback.  The initial problem was that I couldn't get this panorama to stitch.  There appears to be sufficient overlap on the x-axis but maybe not on the y-axis?  (the left/right hand sides of the images).  So I was trying to stitch two adjacent images on a row ...

I'll have to look at this more clearly in Photoshop or something to see why the project doesn't work right (again noting that some parameter was likely changed whilst moving shot locations).
