External Email - Use Caution

Hello Gian, Maybe you can report back with the version of Debian linux you are using so we could look into it. You could try downloading and running the Ubuntu VM image we have with freesurfer 6 and 7 beta release installed on it.  If you are going to run the VM on a linux machine, then you should still be able to follow the instructions listed for setting up the VM on either the Mac or Windows after you install VirtualBox on your linux machine.  The links to the VirtualBox setup instructions for MacOS and Windows are here,https://surfer.nmr.mgh.harvard..edu/fswiki/VM_67 The link to the Ubuntu VM image is on this page where it lists FStutorial_clone_2.7z followed by the link when you click on “image”.  You will need a 7zip program to uncompress it (as explained in Mac and Windows instructions). Once you get the Ubuntu VM running and login as userid developer, you can update the beta 7 release to the latest 7.1.0 release with the instructions below. You can email me directly if you run into something. - R. - - - - -  Updating Ubuntu FS 7 beta release to the current 7.1.0 release - - - - Log into the Ubuntu VM as aid developer. Download the latest release - currently 7.1.0 - from https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.1.0/freesurfer-linu...

Let's assume after the download the archive file is located in your downloads folder under the path, ~/Downloads/freesurfer-linux-centos7_x86_64-7.1.0.tar.gz

Locate your previous version 7 release under the path /usr/local/freesurfer $ ls /usr/local/freesurfer 6.0.0-1  7.0.0-1

Remove the previous version 7 release, here 7.0.0-1, $ cd /usr/local/freesurfer $ sudo rm -rf  7.0.0-1

Expand the archive for the new release from your downloads folder, $ sudo  tar  zxpf  ~/Downloads/freesurfer-linux-centos7_x86_64-7.1.0.tar.gz

Now move the newly created ./freesurfer subdirectory from the archive to be the name of the new release, $ sudo mv freesurfer 7.1.0-1

Check to see files are there, $ ls 7.1.0-1 <output deleted>

Finally, replace your existing $HOME/.bashrc file with the attached bashrc file which will allow you to run either the 6.0.0 or 7.1.0 release.  NOTE - if you have made changes to your $HOME/..bashrc file since you started using the VM, then you may want to merge your current $HOME/.bashrc with the contents of the attached bashrc in order not to lose your changes. You could also diff the 2 files and add manually edit in the changes from the attached bashrc. With the new bashrc in your downloads folder as ~/Downloads/bashrc, then to diff the files, $ diff  ~/Downloads/bashrc  $HOME/.bashrc To simply replace the old bashrc in its entirety, $ cp -p -f  ~/Downloads/bashrc  $HOME/.bashrc Once your new $HOME/.bashrc file is in place (which should use use the 7.1.0-1 release by default), then start a new terminal window.  You should see the following output:

My university created for me a virtual machine in a small analysis cluster. Unfortunately, they installed Debian 4.19.98. I read that freeview has some problems with Debian, and in fact I am not able to open it. Unfortunately I need to visualize the data because we are conducting an anatomical study with patients with lesions. All the processes I ran until now, like automatic segmentation and surface generation like recon all, worked perfectly, but I need to visualize the data. Do you have suggestions to solve this problem?Thanks_______________________________________________Freesurfer mailing listFreesurfer@nmr.mgh.harvard.eduhttps://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
