Dear All,
I encountered some errors while using DPARSF to process resting data. I have tried different versions of DPARSF, there were always errors during the detrend steps:
Hello,
I used DPARSF Basic a few weeks ago to preprocess data from the Enhanced NKI Rockland Sample.
Recently I checked the Autosave .mat file and found that the Slice Number I had indicated was wrong, I had put 33 instead of 38.
However, the slice order ([1 3 5... 34 36 38]) and slice reference (38) were approriate and the prepocessing ran smoothly.
I will run the preprocessing again with the correct parameter but I still would like to know in what way can the wrong slice number affect the preprocessing steps? How can I compare results from the preprocessing with the wrong and correct slice number?
Hello,
I am using DPARSF to run FC on data from the INDI project.
On the main page of the DPARSF website, I read "Given the amount of time and effort for interactive reorienting, the reorient matrices for online data such as 1000 Functional Connectomes Project" and there was a link to download "reorientation matrices"
I can only find reorientation matrices for the ABIDE project on this page. Are there any other reorientation matrices available for INDI projects?
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:
