External Email - Use Caution

Dear FreeSurfer Team,

I'm a Medicine student at Oxford University and I have just registered to FreeSurfer. I just went through the registration process so I'm very new to FreeSurfer but have only run to problems so far and would like to ask for your help:

1. I have register with FreeSurferWiki but can't login: it gives me one of the following errors:

i. "Error 403 Login/Edit allowed only on https/SSL connections Login/Edit allowed only on https/SSL connections Guru Meditation: XID: 1153030795 Varnish cache serve".

ii. Or that it is an "Invalid username or password" (not sure if

2. More importantly I have also tried to install FreeSurfer in Virtual Box (4096 MB Memory; 32 MD Video Memory; Ubuntu 64 Bits) without any success. The Ubuntu system works fine and I have the "freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0.tar.gz" to install FreeSurfer but the being totally new to Linux I have not had success to install it:

i. I'm not sure if at all the files are unzipped from the .gz file.

ii. And I have been unable to create the Bash files to define the environment for it.

3. Finally, I notice that you do have an installation for Virtual Disk Image but the download for it (ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.3.0/freesurfer-Virtu albox-linux-x86-stable-pub-v5.3-full.vdi.gz) is a gz file not a .vdi file as it should be (see picture below):

So either way I wasn't able to get through with the installation and any help is appreciated.

Could you please provide some advice?

Many thanks,

Rodrigo Montenegro
