Robert,

When freesurfer is first started after installation, it adds some lines to your ~/matlab/startup.m file to add the freesurfer matlab files to the matlab paths. But the way those lines are written now, it assumes that the FREESURFER_HOME environment variable is always set, and doesnt check if it isn't (which would be that case if using matlab without having started the Freesurfer setup).

So, please change your ~/matlab/startup.m file to look like this:

%------------ FreeSurfer -----------------------------% fshome = getenv('FREESURFER_HOME'); fsmatlab = sprintf('%s/matlab',fshome); if (exist(fsmatlab) == 7) path(path,fsmatlab); end clear fshome fsmatlab; %-----------------------------------------------------%

%------------ FreeSurfer FAST ------------------------% fsfasthome = getenv('FSFAST_HOME'); fsfasttoolbox = sprintf('%s/toolbox',fsfasthome); if (exist(fsfasttoolbox) == 7) path(path,fsfasttoolbox); end clear fsfasthome fsfasttoolbox; %-----------------------------------------------------%

The new lines are the 'if' statements which check for the existence of the directories before attempting to add to the path, which is the proper thing to do (and future Freesurfer distributions will contain this fixup).

Hello- I am new to Freesurfer and Matlab. I have Matlab 7.4.0 installed on an Intel Mac. I just installed Freesurfer. Now when I start Matlab I get the following warnings:

Warning: Name is nonexistent or not a directory: /matlab. In path at 110 In startup at 4 In matlabrc at 255 Warning: Name is non existent or not a directory: /toolbox. In path at 110 In startup at 11 In Matlabrc at 255

I have tried adding the freesurfer folder to these files to the path for matlab, but the error still occurs. Any suggestions on how to get this error to quit?

Thanks! -Robert
