Have you tried using the VTK software? It is free and was built for CT scans. I am not sure they can export named landmarks to a file, but you could use its Marching Cubes algorithm to produce 3-D surfaces for some of the tissue then export it in a format for INTEGRATE. INTEGRATE is also free and one of the things it is used for is picking 3-D landmarks and writing them to a file. It is what we used for the CAESAR project where we scanned more than 4,000 people with a Cyberware surface scanner in 3 different poses. If you learn how to use INTEGRATE it can be useful, but it takes a little effort to learn. I also understand that while VTK is free it is worth the investment to buy the $60 manual. The VTK website says it can export to the Cyberware format and several others that INTEGRATE can read. If you want to try this you can find out about VTK at: http://public.kitware.com/VTK/ and can ask for a copy of the INTEGRATE software and users guide at this website: http! ://www/3dhead2toe.com
I would be interested to learn what you come up with. We will be needing to pick landmarks from CT Scans too shortly. Thanx, Kath Kathleen M.

I have looked at a number of software packages (Amira, Mricro, eFilm Merge), and while some can give 3D coordinates (Amira, Mricro), none allow sets of these landmark coordinates to be gathered and exported as a text file or spreadsheet. Is anyone out there currently doing this type of CT-based geometric morphometric research who can recommend a suitable software package?
