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.

reho maps distorted after analyses

Dear REST experts,
i have processed the rest fMRI images with REST tool, REHO maps after the REST analyses is distorted , i am attaching the distorted image (left side image in the attachment) as well as the preprocessed image (right side image in the attachment) ,can any one pl. help
thanks in advance

Segmentation failure for T1 coregistered to tilted fMRI

Hello some structural scans failed segmentation and normalization after coregistering to RS fMRI scans that had been tilted forward (30 degrees on the x axis to avoid inferior-frontal dropout).  We used the unified segmentation method.  It seems SPM may not be able to match the structural to the standardized tissue templates if the orientation differs a lot.  We were able to re

ALFF图像结果

老师,您好!
最近搜集了10个被试的静息态数据,按照操作方法使用Basic DPARSF处理数据得到ALFF和fALFF数据,然后用rest viewer查看这组数据并做单样本t检验(alpha sim矫正p0.01),发现有两个问题,谢谢老师予以指导。
1)ALFF的图像(后附图),显示结果有点怪怪的,图中可见一大片的激活改变,而且正激活许多分布在脑池里请教老师为什么出现这个结果?是数据采集的问题还是其他原因造成的?这组数据还能用么?

Brodmann atlas - saving only one area of interest using rest-viewer?

 Hi,
is it possible to create a template of only one of the brodmann area using rest-viewer and the brodmann atlas provided by rest?
I tried it already, but when i select "save current cluster" it always ends up with saving areas.
thanks very much in advance!

静息态数据ANOVA比较之后如何再进行两两比较?

请教一下三组被试,患病组,共病组和对照组,ANOVA比较后,想进一步知道两两的差异还可以用t检验吗?会不会造成了多重比较?REST能解决这个问题吗?
