A problem of preprocessing using DPARSFA

望严老师帮忙分析下原因: 1、试用新版DPARSFA预处理数据时,发现以下报错,另外想把剔除协变量放在滤波前,输入FunImgARWS图像,同样出现类似的报错。 Generating voxel specific head motion for G:\analysis\RealignParameter\sub_001_NC\rp_a20111119_085529ep2dpacedyntmocosunyu3T-018-20s003a001_011.txt...??? Error using ==> class Cannot change the number of fields of class 'file_array' without first typing 'clear classes'. Error in ==> file_array.file_array at 21 a = class(varargin{1},'file_array'); Error in ==> file_array.file_array at 41 a = file_array(a); Error in ==> nifti.nifti at 70 dat = file_array(vol.iname,dim,[dt,vol.be],offs,slope,inter); Error in ==> rest_spm_vol_nifti at 16 N = nifti(fname); 2、另外,想请教一下,怎么评估MNI模板的对称性,我制作了对称的MNI模板后,结果有大的变化,感觉不应该这样,所以想仍然采用non-symmetric的MNI模板,方法学上您认为对文章影响大吗,是否是个硬伤?
