Re: [Freesurfer] Cannot download new Leopard release

Hi Jurgen, the same happens here. The reason for that is that guys pointed the link on the webpage to an nonexisting file. The file uploaded on the server is called freesurfer-Darwin-leopard-i686-stable-pub-v4.0.3-full.dmg while the webpage refers to freesurfer-Darwin-tiger-i686-stable-pub-v4.0

Hi Shriks, use read_label.m after you've converted to a label (or use mris_convert to convert to an ascii surface and use your own reading utility - I don't think we have one).Or use read_patch.m in the native patch format. cheers, Bruce On Tue, 1 Apr 2008, SHRIKANTH KULASHEKHAR wrote: Hi,

Juergen, The site is fixed now. The filename had 'tiger' in it instead of 'leopard'. For the Mac, freesurfer is now built on the Leopard OS. A build for the Tiger OS for the PowerPC is available if anybody requests it. A build for the Tiger OS for the Intel Mac is not available. Nick On Tu

Hello All- When viewing the scalar overlays in qdec, how do I tell which coefficient is being displayed when I select "Regression Coefficients" from the menu? Having more than one regressor, I would expect more than one overlay of coefficients. Am I missing something very elementary? -- ---

Dhruman, Try typing: ldd $FREESURFER_HOME/bin/mris_volmask.bin and look for the libexpat that it expects. libexpat needs to be in that directory. On 64bit Centos, it is looking for it in /usr/lib64, not /usr/lib. You could just make a symlink to the /usr/lib64 dir for that lib. Nick On Tue
