== Access ==
Here are instructions on how to set-up your environment to use the Internal !FreeSurfer Distributions.

The Internal !FreeSurfer Distributions are 'stable' and 'dev'. All computers on the Martinos Center NMR network should have the directory '''/usr/local/freesurfer'''. Inside there, you will see the file '''fsenv'''. Sourcing this will set up your environment to use the stable or dev versions. For example, to use the current stable version (7.2.0), which is what most users should do, use the following setup command:

'''Version 7.2.0:'''
{{{
$> source /usr/local/freesurfer/fsenv 7.2.0
}}}

'''dev:'''
{{{
$> source /usr/local/freesurfer/fsenv dev
}}}

'''NOTE:''' Do not put this command in your .cshrc or .bashrc file!  If /usr/local/freesurfer is down for whatever reason, then your login will not work.

You should see your prompt change and your environment will be set up to run !FreeSurfer. Note that the programs may appear to be in a different location. That's OK, because {{{/usr/local/freesurfer}}} is actually a link to a platform specific version that resides in a different directory, much like how {{{/usr/pubsw}}} works. If you don't know what this means, don't worry.

Your {{{FREESURFER_HOME}}} will actually be {{{/usr/local/freesurfer/7.2.0}}} or {{{/usr/local/freesurfer/dev}}}, etc... so if you'd like to set {{{FREESURFER_HOME}}} manually and without changing your prompt, you can still do so:

{{{
## csh
$> setenv FREESURFER_HOME /usr/local/freesurfer/7.2.0
$> source $FREESURFER_HOME/SetUpFreesurfer.csh

## bash
$> export FREESURFER_HOME=/usr/local/freesurfer/7.2.0
$> source $FREESURFER_HOME/SetUpFreesurfer.sh
}}}
