bmanalyzeGetPaths( varargin )

function h = bmanalyzeGetPaths( varargin )
% BMANALYZEGETPATHS Retrieves URLs for brain images from BrainMaps.org.  
%   H = BMANALYZEGETPATHS(datid) retrieves URLs for BrainMaps.org for
%   given dataset (specified by datid).  Datid (which is a contraction of 'Data ID') is
%   an integer representing the unique ID of datasets. You can find out the 
%   datid of a given dataset by hovering over the dataset's thumbnail at
%   brainmaps.org.  The value of datid ranges from 1 to however many
%   datasets are available (as of 06/13/2006, there are 43
%   datasets available). 
%
%   Notes
%   -------
%   URLs retrieved by BMANALYZEGETPATHS may be used for BMANALYZE input.
%
%   An alternative way to obtain image url's for use with BMANALYZE is to find a brain dataset you
%   want to use at http://brainmaps.org, click on the 'Metadata' link, and
%   then click on 'Generate Paths' to generate a list of all url's for the
%   selected brain dataset.
%
%   Example
%   -------
%   Retrieve image URLs for dataset with datid=43
%
%       bmanalyzeGetPaths(43)
