    REST 提供了很好很强大的ROI时间序列提取（Extract ROI Signal ）功能，可以非常方便的提取ROI的数值，我以前的研究从中受益很多。

    最近的研究，要求不仅仅提取出一个ROI的平均时间序列，还要提取这个ROI中每一个Voxel的时间序列，不知需要如何将该程序修改或重写？多谢指教！

Dear DPARSF forum, dear Chao-Gan,

i struggle with the content of several mat files created during preprocessing.

Hi,

I've processed serveral cases through the VMHC stage of DPARSFA, but now I am getting a new error (below).  Any thoughts:?

Hi all,

Another dummy question. People usually select ROIs to calculate the function connectivities between different brain regions. However, in REST, we do not have enough information to pre-set the ROIs like what we do in Task states. If we use AAL atlas, the brain regions are too large, and it should not be a good way.

So, if we want to calcualte the FC, how to select the ROIs scienfitically in REST studies.

ps. How to view the FC results in REST?  or we need to use other softwares?

Hi,

I'm confused as to the meaning of some of the files created during segmentation.  I ended up using traditional (non-Dartel) segmentation.  It mostly worked fine and I get files like:

Hi all,

Hi all,

I'm not sure what the default mask is.  Is this an "or" mask of the subejcts in the dataset, or not a mask at all?  Also what space is it in?  I'd like to limit the number of voxels in the analysis to just those where I have brain data for all subjects.  Do you have any recommendations?

Thanks,

Matt
