Try stitching to Large Document Format, or PSB in Photoshop.
Apparently PSD supports up to 2GB and TIFF up to 4GB. PSB goes up to 4 Exabyte. Your hard disk needs to be formatted in NTFS format and not FAT.
Yeah. I learned about "big" last year when I scaled a pano up to 53' long (at 150 dpi). The final images (there are two of them) are each about 2.4 GB in .psb format, and exceed the 4 GB size limit for TIFF.
But once you have your huge psb file from autopano...how can you view it easily without using photoshop? Does anyone know of some cool freeware that let's you view large psd files easily? I used to love faststone but it chokes up on these mega panos.

Trying to get the bean counter C++ programmers to go back to basics and read the file header for size BEFORE they allocate memory is probably a lost cause.
Thanks for comment guys! So using .psb format is the solution and I should convert each raw file to psb and then doing the autopano in Photoshop, correct me if I'm wrong.
John_T, I also need to format the hard disk into NTFS format before, right?
Futhermore, can lightroom open the psb file and handle the post processing?
As far as I can see, my .psb files show up in CS6 but not in LR6. Haven't done any recently, but as I recall I have created the stitch in CS6 out of RAW files and when it was complete saved it as .psb.
If you have a modern Windows computer it is unlikely you will have any hard disk formatted in anything other than NTFS.
LR6 now has its own photo merge modules, but I don't know what file formats it will spit out, but I suspect .psb isn't one of them.

This afternoon I finally had the opportunity to make a large print from a 5Ds R image. Until now I've only made crops from larger images or else printed small.
The image is a landscape photograph that I made back in July. Due to slightly tricky lighting — shaded foreground areas but distant clouds in full sun, I exposed for the highlights with the expectation that I would have to push that shadowed areas in post (with exposure, black, and shadows faders), lower the highlights fader to control the brightness of the clouds, and increase contrast to compensate for what amounts to compression. I used the 70-200mm f/2.8 L II.
I'll just say that the 5DsR files perform up to my expectations in the print. The test print is a 4:3 aspect ratio image that was slightly cropped, and I printed it at 22.5" x 30". No surprise — resolution is excellent, as it should be. It will make a very sharp 30" x 40" print, and I'm pretty certain that I can go larger with good quality, too. The pushed shadows look fine.

Here is a small jpg of the specific image — and of course the jpg doesn't demonstrate a thing about the image quality of the print. ;-)
(One more thing. If anyone wants to see what the print looks like and is in the San Francisco Bay Area, I'll probably bring it to this week's meeting of the San Francisco Photography Meetup Group on Wednesday evening. (http://www.meetup.com/photo-437/)
