cvnpath.m

function p = cvnpath(whichpath)
% p = cvnpath(whichpath)
% 
% Return the path specified in 'whichpath'
% Hardcode common paths here, then call this function elsewhere to maximize
% flexibility.
%
% Possibilities:
%   'code'        (common cvnlab code on Dropbox)
%   'ppresults'   (cvnlab pre-processing results on Dropbox)
%   'freesurfer'  (FreeSurfer subjects directory)
%   'fmridata'    (fmridata directory on stone)
%   'anatomicals' (anatomicals directory on stone)
%   'workbench'   (location of HCP wb_command)
%
% eg: fsdir=sprintf('%s/%s',cvnpath('freesurfer'),subjectid) 
%       instead of hardcoding in every function
%
% Note: If you have /stone/ext1 followed by /home/stone-ext1, this ensures
%   that you can access it from any machine, and if we ARE on stone, it
%   will use the faster local route /stone/ext1
