Hi, Thank you for your response! But, I can’t find vertices number of a surface through typing the following command: mris_euler_number noise0.5_0
When I type the command, the terminal shows some information as follow.
euler # = v-e+f = 2g-2: 0 - 0 + 0 = 0 --> 1 holes F =2V-4: 0 != 0-4 (-4) 2E=3F: 0 = 0 (0) total defect index = 2
But I don’t know what meaning of the numbers is. Would you tell me? And, have any other ways to get the vertices number of a surface?
Then, I want to make sure that is image matrix 256 x 256 x 256?
Thank you for in advance!!

Hi Feng-Xian,
the surfaces all live in the surf subdirectory. To see how many vertices a surface contains you can run either mris_euler_numer of mris_info. The thickness is in the ?h.thickness ("curv" format file - one scalar per vertex) and the inflated is in ?h.inflated surface format. You can visualize the thickness in tksurfer by loading the inflated surface then loading the thickness from the file menu using the load curvature option.
cheers Bruce

Hi, I want to check the image matrix after doing autorecon-all. When I look at the text, I see that ÿÿOriginal Data has (1, 1, 1) mm size and (224,
256,
- voxels. Data is conformed to 1 mm size and 256 voxels for all
directionsÿÿ. This is said that that image matrix is 256 x 256 x 256.
Right?
And, I want to know how many voxels do an inflated surface have? Where dir and what text do I to get that?
And, do FreeSurfer have a text that including the value of cortical thickness? I want to know the information of cortical thicknessÿÿs value
at
all pixels of whole brain for each subject. If yes, what text has the information of the value of cortical thickness and where do I find that text? If no, how can I get the information?
Thank you in advance!
