利用matlab的SPM12进行功能核磁共振成像数据处理_Auditory fMRI data(四)

懒癌患者可以直接利用SPM12 batch script的代码对数据处理进行操作,连数据都不需要下载,直接打开matlab,运行以下代码即可。

data_path = fileparts(mfilename('fullpath'));
if isempty(data_path), data_path = pwd; end
fprintf('%-40s:', 'Downloading Auditory dataset...');
urlwrite('http://www.fil.ion.ucl.ac.uk/spm/download/data/MoAEpilot/MoAEpilot.zip','MoAEpilot.zip');
unzip(fullfile(data_path,'MoAEpilot.zip'));
fprintf(' %30s\n', '...done');
