     Dear all, I am using the fc_gui to calculate the functional connectivity between two ROIs of my patient and control groups. I included all my participants in the same analysis (one directory for patients and one for controls). The ROI_FCMaps that are...

     各位老师: 我想做基于voxel的functional connectivity,不知道怎么提取每个voxel的signal sequence?需要什么mask还是software?  谢谢!

    Hello, I am searching for papers discussing the issue on structural connectivity might reflecting functional connectivity (e.g. Greicius, Supekar, & Dougherty, 2009; but not necessarily vice versa; Deco, Jirsa, & McIntosh, 2011). If...

    各位老师好!   我想请教一下各位老师,在fMRI研究中,应该如何来做大脑和行为之间的关系。   1, 在一般的高分和低分极端组设计中,似乎通常的做法是这样的:对两个组进行独立样本t检验,对有差异的脑区即ROI提取平均值,比如ReHo的平均值,然后分别在高分组和低分组内做ROI提取的平均值与某个量表的Pearson相关。但是这样做的效果我得到的不是很理想。有时候得不到显著的结果。有时候得到的结果甚至和独立样本t检验的结果互相矛盾。比如,在高分组中发现某个脑区的ReHo值高于低分组,...

    Hello, I am receiving a bug when extracting the ROI signals (i.e white matter, CSF) for the nuisance covariates regression. The error appears after slice timing, realignment have been done. The error I received is below, I believe it is due to...
