Thomas,

I'm not sure about how to get a transform matrix, but the vertex numbers of a surface patch (flattened or not) match those of the originating surfaces (orig, white, pial and inflated), so the transform matrix may not be necessary for what you want to do.

mris_flatten is used to flatten a patch.

Hi,

Does anyone know of a script that takes a surface patch, flattens it and then gives you the transformation matrix for each verrtex that allows you to put it back into the initial form? The purpose is to do 2D plane geometric operations on the flattened surface and then re-transform the output back onto the original surf configuration. I am working on it in Matlab, so Matlab code would be best. But it could also use FS surf files as input and output. Any suggestions are greatly appreciated!

Best, Thomas
