去线性漂移出错

严老师,我在用dparsf时有warning和报错如下,请您指导一下是哪块出了问题
Warning: Invalid escape sequence appears in format string. See help sprintf for valid
escape sequences.

should i change the voxel size 3 3 3 fixed in dparsf to 2 2 2, that is fixed in SPM 8 when default mode ?

Hi, admistrator  
first, above all,  thank you for providing your program 

Our researchers have studied ADHD adolescent and their brain activity used in fMRI.
Our study is block design and I have analysed this by using SPM8.

头动被试的处理方法

各位老师好!最近在处理一批病人的数据,头动较大(放宽至3mm和3°)的被试比较多,但是被试的总体数量又比较少。想请问一下各位老师有没有对头动的被试的处理的方法。
暂时有两个想法:1.去掉头动较大的时间点。2.不去头动的被试,最后将头动作为协变量去掉。暂时只是这样想,还没有找到文献的依据,不知道具体可不可行,还请老师指点,多谢!

Global mean regression removes all voxels?

Hi, I have been using DPARSFA for preprocessing and it has been working very well so far. I tried to remove the Global Signal nuisance regressor, but after doing so my data has no voxels left -- i.e., when I enter it into a first-level model in SPM, and estimate the model, I get this popup message:
-----
No inmask voxels - empty analysis!
-----

REHO images empty

Dear REST experts,
i have performed the preprocessing of my rest fMRI data followed by the ReHo processing. after running the analysis, i have the rest ReHo*.* image, but this image is empty, can anyone suggest me where could i have made mistake (preprocessed image - smmothed image is looking fine)

关于头文件域含义

各位老师你们好
                 我最近用到rest_Write4DNIfTI里面 

Head.fname - the filename of the image. If the filename is not set, 
%                    just use the parameter.

ICA

各位老师:
     您们好,我最近在做ICA分析,遇到2个问题需向老师们请教。
      1)gift软件下的ICASSO工具箱有两个选项maximun/minimum cluster size to get stabe run, 请问是什么意思?如何填写比较合适。icasso所用原理和mica得到稳定成分的原理一样吗?
      2)如何计算高频信号》0.1hz占该独立成分的功率谱的百分比?
     期待各位老师回答
     祝好!

ICA做脑区分割到最后怎样解决overlap的问题

张寒老师,
      您好,我现在用GIFT软件做ICA功能分区,把我的目标mask load进去后按照MDL算出了最适component进行了ICA运算,出来的ICs有很多都是重叠的,就是说我mask内的voxel对多个IC都有贡献,那么该能用什么软件将这些overlap的voxel进行分类使它们归于一个最相关的IC。还有关于您做的那个听觉分区的图,请教一下用什么软件可以进行颜色标记。rest里的Image calculate做的是nii格式的图,但是ica出来的是img和hdr的图,该怎样的转换进行ICs的求并集,这种求并集能否解决我说的overlap的问题,期待您的答复

       祝好.

GCA error
