Hi,
Thank you for your response! I use the command what you said.
The terminal shows:
euler # = v-e+f = 2g-2: 154901 - 464697 + 309798 = 2 --> 0 holes
F =2V-4: 309798 = 309802-4 (0)
2E=3F: 929394 = 929394 (0)
I guess that 929394 is the vertices number of surface which I want to get.
Right? If not, which value is I want to get?
Then, I run lh.orig and another subjects, I find the value is different from
those. So, the vertices number of surface is not a fixed value and changes
with hemispheres and subjects.
Thank you in advance!!
