between a restricted ROI x gray matter mask region for Degree Centrality

Submitted by jwhnavy on Sun, 02/23/2014 - 07:47

Hi REST experts,

I'd like to perform Degree Centrality analysis within restricted ROI (e.g., only PFC region).
To do so, I do make a correlation matrix between voxels in the restricted ROI and voxels in whole gray matter mask (or default whole brain mask) before applying threshodling (r>0.025) and counting or averaging.

mGCA 结果如何看

Submitted by 精进不休 on Sat, 02/22/2014 - 16:00

大家好，

最近用Rest做了基于系数的mGCA,结果出来了，是个12*12的P值(12个ROI)，但是我不知道这个系数应该如何看，是row to column 还是column to row？有文章说是前者，但是具体为什么我也不懂。

请各位前辈指教。。

谢谢。
