     Dear all, I would like to plot the time courses for two regions in the DMN -- Posterior cingulate cortex and medial prefrontal cortex -- so I can graphically see if the two regions are positively or negatively correlated over time.  I am running...

    大家好,最近我打算用rest试着跑VMHC,出现以下问题: 我直接打开rest的,然后输入数据目录,提示没数据。 我不知道做VHMC需要哪步的数据,我试过这些目录的数据,都提示no data: FunImgNormalizedSmoothedDetrendedFiltered FunImgNormalizedSmoothedDetrendedFilteredCovremoved 应该选择哪一步的数据呢? 谢谢

    Hi Guys, Preprocessed (detrend) my data outside of your toolbox but wanted to use DPARSF to smooth and calculate ALFF, fALFF, etc.  I created the proper folders in FunRaw, put my data in the FunImgNormalized folder, and tried to run just these steps that...

    大家好!向大家求教一个问题:能否采用reho或alff进行纵向研究? 我对同一批人间隔三年进行了两次resting-fmri的扫描,但是我不知道采用配对样本t检验对前后数据进行处理在方法学上是否行得通,因为fmri的可重复性并不是特别好。另外,如果可以的话,在数据处理时,除了采用配对样本t检验之外,还有没有其他的事情需要引起注意(就是和横断面研究有什么区别)?先谢谢大家了!

    请教严老师和大家一个问题,我把20个患者和20个健康对照组的ReHo数据做了双样本t检验,使用AlphaSim校正,p值取0.05,但是结果显示双侧半卵圆中心脑白质大片脑活动增强的区域,不知道是怎么回事啊?迫切期待您们的帮助和解答!PS:只有一名患者头动超过1mm,其他的配合都很好。附图:图1是患者组单样本t检验的结果,图2是对照组单样本t检验的结果,图3是患者组-对照组双样本t检验结果。

    老师,您好! 请教一个问题,我用REST做静息态的数据的filter分析时,结果感觉有问题。如图所示,左边是filter之前的数据,右边是filter之后的数据,请问问题出在哪?使用或不适用mask都出现类似的结果。我用的是Matlab7.11.0,rest1.6。多谢赐教!

       老师您好:             对于提取时间序列有个疑问,选择一个ROI,我们能够得到它的一个时间序列,比如210个时间点,就有210个数据,那我们如何做比较呢?比如两组间的比较.
