Creating equirectangular projection from 6 faces

I have 6 square cube faces for a panorama. How can I make this into an equirectangular projection using PanoTools?

Stuart
I don't know how to do it in PanoTools but it was really easy in iPIX Interactive Studio with either the Format Pack or Enhancer Pack
If you can find an iIS user than can do it for you.

Stuart, Are you using Panorama Tools with one of the gui front ends (PTGui, Hugin or PTAssembler), or do you want to know how to do this with the Panorama Tools plugins in Photoshop?

Hi Stuart,
I don't know how to make it with PanoTools, but I know that cube faces can be converted into a spherical panorama with Panoweaver.

One of the frontends (I've got Hugin).

Dorin, Your tutorial uses an old version of Hugin. The version I have installed is 2009.2.0.4461 and is significantly different. I found it hard to get a stitched result that was a completely seamless blend of the images. Blending is by Enblend by default, which gave a poor result. The only way I managed it was to generate the 6 warped images with Nona and manually assemble them into a PSD file (with layer masks copied from the alpha channels) and then flatten the file. There's a utility PTTiff2psd.exe supplied with Hugin that should do this but it didn't work on my system. That's as far as I have got so far in my tests.

John, that was indeed made couple of years ago.
Couple of minutes ago I checked with the latest Hugin using nona_gui.exe from this distribution
The files needed along, of course, with nona_gui.exe
Cubic2EquiNona.bat
content:
nona_gui -o Pano_equi.tif Cubic2EquiNona.txt
Cubic2EquiNona.txt
content:
p f2 w6000 h3000 v360 E0 R0 T n"TIFF c:NONE"
m g1 i2 f0 m2
o w1910 h1910 f0 p0 r0 t0 v90 y0 u10 m0 n"cube_0.tif"
o w1910 h1910 f0 p0 r0 t0 v90 y90 u10 m0 n"cube_1.tif"
o w1910 h1910 f0 p0 r0 t0 v90 y180 u10 m0 n"cube_2.tif"
o w1910 h1910 f0 p0 r0 t0 v90 y270 u10 m0 n"cube_3.tif"
o w1910 h1910 f0 p90 r0 t0 v90 y0 u10 m0 n"cube_4.tif"
o w1910 h1910 f0 p270 r0 t0 v90 y0 u10 m0 n"cube_5.tif"
launching Cubic2EquiNona.bat will produce an equirectangular from those six cubic faces, which are required to be in the same folder
one can adapt (change)
w1910 h1910 with the actual cube face size
and
w6000 h3000 with the actual equirectangular size
