== To configure FreeSurfer ==

1. Copy the license file into freesurfer/ and rename it to ".license" (no quotes) if necessary.

2. The file freesurfer/FreeSurferEnv.csh is a csh (c-shell) script that will configure your environment so that you can use FreeSurfer. It sets a few envrionment variables and performs some sanity checks. If you are comfortable writing shell scripts, you may wish to set up your system differently, but we recommend the following:

Create a file in your home directory called something like "SetUpFreeSurfer.csh" with the following contents:

     `# Local setup.` [[BR]]
     `setenv FREESURFER_HOME <full path to freesurfer/>`[[BR]]
     `# Additional configurations will go here.`[[BR]]
     `# Call configuration script.`[[BR]]
     `cd $FREESURFER_HOME`[[BR]]
     `source Free``Surfer``Env.csh`[[BR]]

The full path to your freesurfer directory should be something like:

2. If you wish to designate a non-default subjects directory, add the following line in the 'additional configurations' section, before 'cd $FREESURFER_HOME' is called:

     `setenv SUBJECTS_DIR <full path to subject dir>`

3. If you installed the MINC tools, then add the following lines to the additional configuration section:

     `setenv MINC_BIN_DIR /usr/pubsw/packages/mni/current/bin`[[BR]]
     `setenv MINC_LIB_DIR /usr/pubsw/packages/mni/current/lib`

If you did not install the MINC tools, then add the following line in the local setup section:

     `setenv NO_MINC`

4. If you do NOT intend to use the functional tools, then add the following line to the additional configuration section:

     `setenv NO_FSFAST`

If you do intend to use the functional tools, then add these lines to your `~/matlab/startup.m` file:

     `fsfasthome = getenv('FSFAST_HOME');` [[BR]]
     `fsfasttoolbox = sprintf('%s/toolbox',fsfasthome);` [[BR]]
     `path(path,fsfasttoolbox);` [[BR]]

5. Save the file. You will need to source this file every time you want to use Freesurfer.

6. Make sure you are using csh or tcsh. You can check by typing 'ps' at the command line. If you do not see csh or tcsh as one of the processes in the right hand column of output, you must change your default shell to csh or tcsh or explicitly launch csh or tcsh first.

To explicitly launch csh or tcsh (tcsh is recommended), simply enter the following command:


You may notice your prompt change. Note that some of your login files may not be run in the new shell environment. See the man pages for tcsh for details.

7. Source the script.

     `source Set``Up``Free``Surfer.csh`

You should see output like this:

     `Setting up enviroment for Free``Surfer/FS-FAST`[[BR]]
     `FREESURFER_HOME /home/freesurfer`[[BR]]
     `FSFAST_HOME /home/freesurfer/fsfast`[[BR]]
     `AFNI_DIR /home/freesurfer/afni`[[BR]]
     `FSL_DIR /home/freesurfer/fsl`[[BR]]
     `SUBJECTS_DIR /home/freesurfer/subjects`[[BR]]

If you see any warnings, you can probably safely ignore them, but make sure they are not notifying you that it can't find something you think should exist.

If you see any error messages, make sure you have performed the installation process properly, and that your `FREESURFER_HOME` setting is correct.

From now on, you only need to source the Set``Up``Free``Surfer.csh script once in a shell session to be able to run FreeSurfer. You may want to do this in our shell's login scripts (i.e. .cshrc or .tcshrc).

To use FreeSurfer

See $FREESURFER_HOME/docs/FreeSurferManual.pdf to get started. See also http://surfer.nmr.mgh.harvard.edu/docs/ See also recon-all -help

Mac OS X Notes

1. You may need to use the OS X minc 1.2 available from the MNI website. There are bugs in it, but MNI has promised a fix soon.

2. You should use fink to install the additional libraries that FreeSurfer needs, such as libtiff and libdl. You can get fink from:

Once you've installed fink, there are two packages you'll need to install:

  • libtiff BR dlcompat-dev

Using binary mode to transfer files.

If you are getting files, then 

   ftp> cd transfer/outgoing

If you are putting files, then

   ftp> cd transfer/incoming

Then go to a particular directory.

For those inside NMR center, go to /space/outgoing and put files in its subdirectory. You can get user transfered files from /space/incoming. It takes 5 minutes or so to actually see the files there after the transfer.
