Hi,

I just want to move the panorama (in the Panorama editor?) so the the final equirectangular image is as I want it. That is - just slide it to the left or right. 

I'd like to do this without upsetting the horizon at all!

I used to be able to do this in Photoshop too, with the equirectangular image, but I can't remember how.... It would be nicer to do it as close the the 'source' s possible, so it's right before processing elsewhere.

I am just re-starting creating panoramas after a bit of a break, sorry!!

You can click the 123-button (Numerical Transform) in Pano Editor, enter
an arbitrary value for Yaw and click Apply repeated times. Negative
values pan in the other direction.

You can use the Set Center Point button and set a new center point on
the horizontal line, although this might change your horizon slightly.

Use the Offset filter from Filter menu with the wrap around option
checked. This only works on a flattened image, but it's nice to check
whether there's a visible seam line due to some non-global processing.

Use the numerical transform tool to apply one or more yaw increments to give the required amount of shift.

Use Filter->Other->Offset with the wrap option selected in order to shift the image horizontally.

Is this really true?  It seems to work ok on a layer, and if there's a layer mask attached, it shifts that automatically too.

Well, this was a bit shortened. Of course it works for layers, but it
works only for one layer at a time, so if you use it on a layered
panorama it will break it (unless of course, you repeat the operation
for all layers).

In the PTGui Help Index under Panorama Editor Window there is a section on 

Set Center Point


In Photoshop I think the command you are looking for  is

Filter => Other => Offset

Exactly so. It's simple enough to select each layer in turn and hit
Command-F / Control-F to repeat the last filter operation, but it's all
too possible to miss a layer if there are a lot to deal with.

Thanks for all the replies, I'm a bit embarrassed I'd missed the button to do this in the Pano Editor itself, but it had been a long time since I'd used PTGui. I can let myself off a little more lightly about the Photoshop option as that was buried in a slightly obscure spot :-)

I know this is an old post.. I just had a customer request images that would be on my second set of shoot after the north. So I searched and found this.. it was helpful. I did job in minutes!
Thanks
Kind regards
Sam

You're welcome. I use this on every pano now so the equirectangular image looks it best when viewed as a regular image.
