​Hello Gonzola,

I use a CentOS7 VM image (on virtualbox) originally downloaded from osboxes.org.  After downloading and bringing up the image, I installed various packages for freesurfer.  But apart from my image being CentOS7 (and not CentOS6), I think it is currently too large for it to be practical to upload/download.

You can download CentOS6 images from osboxes.org, https://www.osboxes.org/centos/

If you scroll down that page you will see the latest CentOS6 image is 6.10, followed by previous 6.X releases.

Some of the packages I installed are,

qt-create qt-config.x86_64
qt5-qtx11extras.x86_64 qt5-qtx11extras-devel.x86_64
boost.x86_64 boost-devel.x86_64
tk-devel.x86_64
opencl-filesystem.noarch opencl-headers.noarch
opencv.x86_64  opencv-devel.x86_64
git-annex
