[Freesurfer] centos4_x86_64_V4.0 vs. centos4_V4.0

Hi all,

I had tried to play with FreeSurfer centos4_x86_64_v4.0 on my laptop in the past two days, and found that the tksurfer did not show the brain surface correctly. Today, I installed the centos4_v4.0 on the same laptop. This version seems to work well. The only difference I have noticed by far between these two versions is that the centos4_x86_64_v4.0 needs libglut.so.3, but the centos4_v4.0 does not. Can anybody tell me why this difference makes sense here?

I also found that I could not input the slice # with keyboard in the TKMedit Tools window. Can anybody tell me how I can do that?

My system:

HP NC8430 laptop (ATI X1600 video card) Fedora 6 (X86_64)

Thanks in advance,

Xiangchuan Chen
