That's great ! Thank you !

Panotour and Panotour Pro only accept images with a spherical projection or a planar (flat) projection.

But perhaps you are hand coding for krpano and not using Panotour or Panotour Pro?

Why did you particularly want to use an image with a cylindrical projection?

I did download your car/hall example.
I did import your spherical into apg 3.0.3 and did detect it with cylindical procejtion. I used 8mm  (with very curved result, so cropping has to cutoff most of bottom and top, but keeping the width left->right direction uncut.) the resulting pano was not in 2:1 ratio (I had in this case to add some pixels on nadir/bottom line). ptp 1.8 had not problem to create a seamless tour. but as you may have recognized... its detectes as spherical pano because of 2:1 ratio.
I did also raise the focal value up to 85mm with result that curving gets more and more reduced, so cropping is only cutting a small part).
using planar projection I had not to crop the pano.

creating a virtual tour is another side of the coin... as Andrew did mention.

because of the crop you did in apg lines got cut on zenith and nadir... so a seamless border cant be possible because content was cutoff. you have to know how many was deleted. than you can enlarge your pano to get back an 2:1 ratio. you can fill it with black pixels or with an nadir/zenitz patch logo or so.

But if you wanna create a 360x180 tour with cylindrical panos it would be much easier to stick on spherical of planar projection instead of cylindrical - no cropping is needed, so no content get removed and a seamless tour is easy to create.

I don´t need it for panotour pro. Take a look at this, these requirements I have to fulfill:

Virtual Tours.
Cylindrical virtual tour files are ideal.
Ideal Image Size: Minimum of 7000 pixels wide x 1750 pixels high.
Ideal Aspect Ratio: 4:1 height to width ratio.
Ideal File Types: Cylindrical JPEG or MOV

Where does the specification of these 'requirements' come from?

using my mehod from above...
I have to set the focal of the two images. If I take 8mm I get very curved result. to maintain the horizontal pixels untouched I than have to crop a lot.
so if I use 85mm instead than nearly no curving does take place and very less croping is needed. If I crop in any case and render it than the resulting pano does have perfect seams (using panotour pro 1.8). in cropping mode you can see the pixels... so you can get finally your 4:1 ration with some try and error.
