    Dear SONG Xiao-Wei and YAN Chao-Gan: Thank you for making REST fmri analysis software available. It has been very helpful in my analyses. I have a question about how the software analyzes covariables. I notice that you add both a linear and a mean regressor...

    In a few earlier studies, spatilly smoothing was performed before ReHo analysis. However, Mr. LONG Xiang-Yu found that, for some voxels, the ReHo value is very high because spatially smoothing certainly increase the local similarity. That...

    我看了一篇关于resting的文章,上面有这么一段话:After slice acquisition correction and head motion correction, the fMRI was normalized to the standard SPM2 echoplanar imaging template, re-sampled to 3-mm cubic voxels, and then  spatially smoothed with a Gaussian kernel of 4...

    用SPM5的PairedTTest处理数据时,选择刺激组和对照组数据的先后顺序对结果有影响么? 我分别试了对调它们的顺序,然后contrast都是1 -1,发现结果一模一样,T值的正负也是一样。 如果说数据选择的先后顺序没有影响,那应该如何来解释结果呢?比如说刺激数据在前,对照数据在后,contrast是1 -1,那T值是正值的脑区代表的是刺激>对照,还是刺激<对照?

     Dear All,  I am trying to analyze a rest condition with rest toolkit, but when I run both ReHo and ALFF with either default mask and no mask option the analysis stops because of mask size error. Could you please help me to overtake this problem and...

    我按照你们的那个视频教程处理了一组静息态数据,用求reho的方法做的,里面有一步是将得到的smRehoMap——图像减1,我想向各位老师请教一下在什么情况下能够得到reho的值为1?使得减1后为0.谢谢! 祝好!
