UpdateFreeview - Free Surfer Wiki

This page describes how to update Freeview within a FreeSurfer v6 installation. On Linux this involves updating a single file in your FREESURFER_HOME/bin directory. On Mac it involves replacing the Freeview.app folder in your FREESURFER_HOME directory. A backup should always be made of the file (or directory) before it is replaced.

Please note the development versions of Freeview will contain the most up to date features but lacks the rigorous testing done before a major release. Therefore, it is imperative that you back up your existing version before replacing it with the development version.

Linux

NOTE: if you are using a version of freeview released before Nov 2018, you must run the following commands (with FREESURFER_HOME properly set) to update the appropriate Qt and VTK libraries . Otherwise, you can skip to step 2.
```
rm -rf ${FREESURFER_HOME}/lib/qt ${FREESURFER_HOME}/bin/freeview.bin
wget -qO- https://surfer.nmr.mgh.harvard.edu/pub/data/fvlib/freeview-lib-update.tar.gz | tar xvz -C ${FREESURFER_HOME}/lib
```
Create a backup of your existing freeview file (this may require sudo access):
```
cp $FREESURFER_HOME/bin/freeview $FREESURFER_HOME/bin/freeview.backup
```

Download the latest development version of freeview using the following commands. This may require sudo access:

wget https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev_binaries/centos7_x86_64/freeview -P ${FREESURFER_HOME}/bin
chmod +x ${FREESURFER_HOME}/bin/freeview

You should now have the new freeview application which is opened by typing freeview on the command line (after sourcing Freesurfer):
```
freeview
```

Mac

Go into your $FREESURFER_HOME and create a backup of your existing freeview app (this may require sudo access):
```
cd $FREESURFER_HOME
cp Freeview.app Freeview-backup.app
```
Download the dev, standalone freeview tarball from here:
freeview_osx.tar.gz
Untar freeview within your $FREESURFER_HOME (this may require sudo):
```
cd $FREESURFER_HOME
tar -xzvf /path/to/freeview_osx.tar.gz
```

4. If you are replacing freeview in a stable freesurfer release, then you must also remove the line "source $FREESURFER_HOME/sources.csh" from the $FREESURFER_HOME/bin/freeview script
