Hi Bruce, Thank you. Would need help from you guys.
Firstly, I would like to clarify from you if I am on the right path with respect to the procedure that I intend to follow? I mean a file like left_hippocampus.nii is the right output to go for or is there any other output from FreeSurfer that would be a better approach to this problem? Any software that you suggest would be good for this purpose? My ultimate goal is to compute a lot of textual features (like the wavelet based ones) but the immediate goal is to extract the Haralick features which seem easy to compute to begin with. If not this approach, then how do you suggest I should go about it?

Unfortunately haven't come across much literature or standard toolboxes to do so. Do you guys happen to know any? To be precise, the procedure that I intend to follow - 1. Use recon-all process on the original mri scan 2. Using files like left_hippocampus.nii ( which look like just masks to me), create a gray scale image of the left hippocampus. 3. Use this gray-scale image to construct co-occurrence matrix. 4. Compute the corresponding Haralick features I want these features for the 3D image itself. Is there a way to carry out the complete process mentioned above in Freesurfer itself? Or any other software/toolbox that can be combined with freesurfer? Appreciate any help.
