Dear Buche,

Thank you very much for your quick reply.

Do you mean those lines: (from recon-all. log)

==================

gca peak = 0.27536 (62)

mri peak = 0.11940 (97)

Right_Hippocampus (53): linear fit = 1.55 x + 0.0 (325 voxels, overlap=0.000)

Right_Hippocampus (53): linear fit = 1.55 x + 0.0 (325 voxels, peak = 96), gca=96.1

===================

If this is what you meant, can you shed some light on this log. What "gca peak" / "mri peak" means? And what the number insight the parentheses represent ?

Thanks in advance,

Assaf

Hi Dov

I think it writes out the log posterior at each iteration of the aseg (mri_ca_label)

cheers

Hi there,

I'm wondering if there's any parameter which can assess the correctness of
the freesurfer's segmentation ( the aparc.a2009s+aseg.mgz file).

--> Assuming the freesurfer's algorithm fitting/minimizing an objective
function, right ? If so, where I can find the value of this
fitted function ? (or RMS value ?)

Thanks in advance,
Dov
