Hi Bruce,

Thanks for your response. Actually I want to use the fast marching toolbox to further analyze the pial surface that FreeSurfer has reconstructed automatically, but according to the procedure only the pial surface will be used for fast marching process and I found out the input file of fast marching is a 256*256*256 matlab file which I could just load in matlab but couldn't see any detail. Do you think I can use the *freesurfer_read_surf*function in matlab to transfer the surface?

Best, Yunxin

Hi Yunxin

the surface lives in a continuum and is 2D. Do you mean filling the space between the ?h.white and ?h.pial surfaces? We do that as part of recon-all and create ribbon volumes in the mri dir cheers Bruce

Hi dear all,

...

I'm new here and I've a simple question that how could I transfer the reconstructed pial surface file(like lh.pial) into a 256*256*256 matlab matrix used in later fast marching process?

Any suggestion will be appreciated! Thank guys.
