Is there any way to export a "?h.patch.flat" to an ascii file format or any other that can be read in to matlab?

Hi Ajay,

I'm not sure I understand. Where did you get the patch? Not from FreeSurfer? You should be able to display activations on any surface configuration, as long as the functional data is registered to the orig volume.

Hello Everyone,

I have the following problem.

I have a section/patch of the Cortical Surface (Auditory area.) which I would like to unfold/flatten.

The data is in matlab and I have it as vertex and faces of the cortical surface.

I know how to write it to a ?h.pial.asc file format from matlab.

I also have activation maps from SPM2.

My questions are :

1. Can I read this surface in freesurfer and an unfold/flatten it ? If yes

how ?

2. Can I overlay the activation maps in freesurfer on to the cortial patch I

described above? If so could some one list the possible steps please?

3. Finally if I can indeed ufold the above mentioned cortical surface will I

be able to export it back to .asc file format?

Thank you

Ajay
