Resting-state fMRI topics

no result after performing one sample t-test for the mrehomap

hi
i got two rehomap after performing reho analysis. after that i used the mreho map for statistical analysis.
there was no error and t-test was completed sucessfully, but when i overlayed it on ch2 template image. it was just a blank image(like plain colour)

subjects not listed

With DPARSF basic edition, everything works fine, but when I use the DPARSF advanced edition the subjects are not listed, although each has the dicoms in a folder with the subject code in the FunRaw Folder in the Working Direktory, that is correctly set (like before). Does anybody know why the DPARSF toolbox does not recognize the subject folders!?

Thanks a lot!

mask与统计学分析

最近做组间统计的时候遇到一个问题,我用rest image calculator把三组单样本显著的区域做了并集,然后在这个mask内做两组间的对比,我发现有点问题,回头查看mask内有1、2、3值,应该是对应于三组,将这一mask1、2、3全部统一为1后,结果不一样了,论坛老师们是否可以帮忙分析一下?

DPARSF老是报错和警报

首先谢谢老师分享您的研究成果!我是个初学者,因为看了老是的软件介绍才打算做静息态相关的研究!但是运行没有成功过。
我的环境是windows xp sp2 64bit/windows xp sp3/matlab2012b/2010b rest1.8 DPARSF 2.2_130224 ;
LINUX UBUNTU12.04 64BIT/matlab2010b rest1.8 DPARSF 2.2_130224

DPARSF老报错

最近用DPARSF老出错,从slice timing就开始,但是单独做slice time又没事,现在我把slice timing后的又重新做,跑了一会儿又报错,请严老师看看怎么回事,如下:
Failed  'Realign: Estimate & Reslice'
Error using ==> spm_bsplinc
File too small.
In file "D:\Program Files\MATLAB\R2010a\toolbox\spm8\spm_realign.m" (v4152), function "smooth_vol" at line 405.

自身前后研究的配对t检验选mALFF还是ALFF更好?

请问:1.自身前后研究的配对t检验选mALFF还是ALFF作为统计指标更好?
        2.在得到前后差异的脑区后,将其作为ROI,在每个被试的原始图中提取ALFF值还是mALFF值或者zALFF?目的是将前后两次扫描的该ROI的平均ALFF值差异与症状变化分数在SPSS中做相关分析。
先谢谢了

REST1.8报错

在用REST做correlation Analysis时报错如下:

新版DPARSF报错的问题

老师您好,我用DPARSF121225和130309版本处理数据老师出现问题,因为数据以前都处理的没有问题,试了很多次还是不行,麻烦您指导一下如果调程序,数据的参数是时间点130,扫描层数48,隔层扫,TR=3s,没有结构项数据,比如:
1.在去线性漂移的时候报错
??? Error using ==> ctranspose
Out of memory. Type HELP MEMORY for your options.

Error in ==> rest_detrend at 40
