又来麻烦各位老师了。 我做了一下正常对照组的FC单样本T检验，发现正连接图激活面积很大，包括了默认网络脑区，不知道是哪出了问题，是不是方法上有问题？谢谢。 (我选了后扣带回的直径6MM小球作为种子区，VOXEL WISE，去除四个协变量，单样本T检验后在rest SLICE VIEWER中处理，ALPHASIM校正，RMM=5，P=0.05) XJVIEWER显示结果只有一个大CLUSTER，有一万四千多VOXELS（共28个CLUSTER）其它是几或几十，大部分是十以下。 附件中有图

各位先进： 我又来问问题了 谢谢严老师之前的回复，前几个在论坛提出的问题都解决了。但是最近在跑Dartel的时候出了问题如下： 请各位高手在解答，感激不尽 Running DARTEL: Create Template. ------------------------------------------------------------------------ Running job #2 ------------------------------------------------------------------------ Running 'Run DARTEL (create Templates)'

各位老师好： 请教一个问题，我想将Rest自带的几个mask利用reslice image将voxel size由3*3*3重采样为2*2*2，保留原始空间信息，（设置情况见附件一），结果报错为 ??? 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 41 a = class(a,'file_array'); Error in ==> nifti.nifti at 70

严老师您好： 看了些文献，有的文献中提到了双样本t检验时要做 random effect analysis， 而有的没有？想问下，这个需要做吗？

Hello everyone, I am just beginning my resting state fMRI analysis, and I have been running into an error. I have created a folder in the working directory called FunImg, where I have added folders for each subject. In that folder, I added the .img file for the resting state scan. Therefore, the file path is created as follows: Working Directory\FunImg\Subject#\rest#.img

严老师： 你好！ 我在用dparsf成批处理数据时，报了这样的错误： Saving Parameters.. Done 'Normalise: Estimate & Write' Done Moving Normalized Files:sub1 OKMoving Normalized Files:sub2 OK??? Error using ==> copyfile No matching files were found. Error in ==> DPARSF_run at 551 copyfile('*.ps',['..',filesep,'RealignParameter',filesep]); Error in ==> DPARSF>pushbuttonRun_Callback at 935

严老师： DPARSF里有Extract AAL time courses (90 regions)这个选项，这个该怎么分析呢？是不是小世界分析啊？能不能指教一下怎么分析，谢谢！
