严老师,
您好!
我是首都医科大学宣武医院的研究生。我现在在做帕金森病认知障碍的脑功能连接的研究。用的是您的DPARSF来处理数据。
我的第一批数据按您的教程顺利做完了。但是第二批数据则老出错。我尝试了重新装软件等,但总是有这样那样的问题,但我都看不懂。
最多的错误如下:
Removing the linear trend: E:
Read 3D EPI functional images: "E:\Analysis\FunImgNormalizedSmoothed\PD27"..............................................
??? Error using ==> ctranspose
Out of memory. Type HELP MEMORY for your options.
Error in ==> rest_detrend at 40
DPARSFA error when stopping and restarting pipeline
1) Processing the NIFTI dataset through Slice Timing alone works fine.

老师:
您好。我用VBM比较两组被试灰质差异,想用Alphasim进行校正。标准化后得到的图像voxel size为1*1*1。我有以下几个问题:
1、在用REST Alphasim计算时,mask应该用全脑的还是用灰质的?
2、如果选择灰质mask,是不是可以用spm/apriori中的灰质图,然后用rest中的image calculator,设定i1>0.2, 得到灰质mask后再重采样成1*1*1,这样制成的灰质mask是正确的吗?假如我做白质的分析,白质mask是不是可以直接对rest中提供的WhiteMask_09_61*73*61进行重采样?3、在REST Alphasim计算时,由于voxel size为1*1*1,那么rmm是不是可以选择2?
请老师指教,谢谢!
各位老师好,请问一个关于提取全脑时间序列的问题。

我目前正在进行的课题需要分别提取全脑每个VOXEL的时间序列。我已使用dparsf完成原始数据的预处理,接下来应该怎么操作呢?
我在论坛中看到有人提到可以使用rest_to4d这个函数,
我在MATLAB中输入 rest_to4d(‘J:\Analysis\FunImg\sub1‘)
报错如下:
Read 3D EPI functional images: "J:\Analysis\FunImg\sub1"........................................??? Error using ==> rest_spm_slice_vol
File too small.
Error in ==> rest_spm_read_vols at 34
Y(:,:,p,i) = rest_spm_slice_vol(V(i),rest_spm_matrix([0 0 p]),V(i).dim(1:2),0);

I am a new user of this amazing REST toolbox. I have a question regarding the threshould on the viewer.
Why the range of the threshold is set differently for each subject? What does the P =1 under the threshold represents? And Technically, how can I save a cluster of activation e.g in the right hippocampus?
Thanks
Nahla
