应用Rest reslice image报错

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

Error with Detected Time points

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

关于dparsf报错的问题

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

Moving Normalized Files:sub1 OKMoving Normalized Files:sub2 OK??? Error using ==> copyfile
No matching files were found.

关于回归协变量

各位老师:
新年好!元宵节快乐!
我有一个疑问,在DPARSF做功能连接时,有一步要回归协变量,我在想后面的提取ROI时间序列和功能连接,是不是都在回归了协变量之后做的处理?那在统计分析的时候,双样本t检验还要输这些协变量文件吗?
谢谢老师!

如何查看xjview的结果?

请教一下,做组块时,查看脑区激活,在xjview中如何分析?
例如一下的一个cluster该如何分析?
Cluster 1
Number of voxels: 149
Peak MNI coordinate: 45 -63 -36
Peak MNI coordinate region: // Right Cerebellum // Cerebellum Posterior Lobe // Tuber // undefined // undefined // Cerebelum_Crus1_R (aal)
Peak intensity: 3.7961
# voxels structure
149 --TOTAL # VOXELS--
149 Right Cerebellum
149 Cerebellum Posterior Lobe

关于进行ALFF、fALFF以及功能连接处理时的报错问题

老师:
您好,我将手上的一批BOLD数据在进行预处理时,均没有出现任何报错,但是,当我用DPARSF进行ALFF、fALFF、以及功能连接操作时,matlab则出现了以下报错:
Computing ALFF with: "K:\yz10test\FunImgNormalizedSmoothedDetrendedFiltered\003"
Read 3D EPI functional images: "K:\yz10test\FunImgNormalizedSmoothedDetrendedFiltered\003".??? Out of memory. Type HELP MEMORY for your options.
