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

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
