Hi Mabula –

I wouldn’t worry too much about the error I was receiving. I eventually found that the problem was coming from trying to integrate the mosaic with the Integrate mode of Reference. Once I changed that to Full, I stopped receiving those errors and the combined panels were no longer ending up the size of a single panel. So, this one was entirely operator error.

One suggestion – I imagine there isn’t a scenario where someone would choose Mosaic in 4) Register and then want to use Reference in 6) Integrate. Perhaps it would be helpful to have a sanity check in Integrate that pops up a message if someone has chosen Mosaic and then Reference – something like “are you sure you want to use Reference? Mosaics usually should be integrated with “Full”.

I did find that APP could complete the integration if I chose overlap of 3 panels (in this mosaic all of the panels touch a panel on either side, except the end panels only overlap with 1 other panel).

As far as the 88%, what I was seeing with the error was that APP would try to do the 1st LNC correction. At the end of that initial pause, it would NOT go on to the normal subsequent LNC steps. Rather, it would advance from 30% to 88% and then issue the error. Again, this is a user triggered error, but I thought you may want to know the sequence where it was occurring.

I’m still having some problems with this Mosaic in having the panels properly register and then have the projection look correct. These 14 panels are portrait oriented side by side along the horizon line for about 210 degrees (give or take). I’ll be combining them with a similar mosaic of the landscape below this to make a panorama of my surrounding mountains with the night sky.

Using Equirectangular or Rectilinear projections ended up creating significant warping of the panels on the ends of the mosaic. I was able to use Photoshop’s Photomerge with a Cylindrical projection, and that seemed to align the panels as I expected. However, I’d certainly be interested in finding out how I might do something similar with APP.

I know you’re very busy, and this is not a priority in any way. But, I did upload the 14 panels (I reduced them to 50% size, but they’re otherwise unaffected. I also uploaded a jpeg of the Cylindrical projection so you can see what it should look like.
