Thanks, the resolution is: 1*1*1 (see below):
data_type      INT16
dim1           160
dim2           240
dim3           256
dim4           1
datatype       4
pixdim1        1.0000000000
pixdim2        1.0000000000
pixdim3        1.0000000000
pixdim4        2.2999999523
cal_max        0.0000
cal_min        0.0000
file_type      NIFTI-1+

The aseg looks like the grray matter also "eat" a little bit of the cerebellum, but they are very close to each other, so not easy to tell how much.

The third one I'm not so sure about the tiny twisted knot of the red and yellow lines, maybe can be ignored?

cheers,
Kaiming

yes, the first one looks like an issue, psossibley a topological defect fixed in the wrong way. What is the resolution of this data? The second one looks like the surface dips into the cerebellum. What is the aseg like? The 3rd one looks ok, but I'm not positive that I understand what you are pointing at. The surface will not track subcortical gray matter, only cortical

Dear Bruce,
that sounds good. How about the following three which I think may have some specific problems in which as mentioned in the file name, especially in the cerebellum
one, I think there are a lot of slices similar to this one: the gray matter seems always cover a little bit part of the adjacent cerebellum. So do you think
whether they have problems or not?

Thanks,
Kaiming

      Hi Kaiming

      those look pretty good. It's impossible to tell for sure from a  single slice.

            Dear guys,

            I have a simple question in the manual edits parts.

            I am using freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0 with Ubuntu 13.10, for a  trial on a 3T adult data, and I attached the data 2
            screenshot common
            examples here, personally I am not sure if the wm boundary seems good or not. So I hope if you can help have a look and see if this data
            has any place need edits.
            And also usually, for a 3T data like this, how many edits will be approximately needed? I mean will it usually cost several corrections
            enough? Or 10s? 30s? or
            even more? (sorry for the oversize of last email attachment)

            Great thanks,
            Kaiming
