Dear rsFC analysis experts,
I have some questions with respect to DC analysis.
各位老师好：
请问DPARSFA最新版本计算degree cenrality得到的是global FCD还是local FCD？
另外，network centrality与node centrality 或nodal centrality是否为同义词？
感谢您的热心解答。

大家好！我想请教各位老师，怎样才能分出扫描顺序呢？
Dear experts,
I'm quite new with the toolkit REST,
and I have a doubt:
I have two groups (paitents-healthy controls) and I have 2 resting-state runs for each subject.
Once I performed ReHo (and ALFF/fALFF) calculation for each single run,
请问张老师，在GIFT里面如何将成分导出来呢？
Dynamic brain connectome (DynamicBC) analysis toolbox is a Matlab toolbox to calculate Dynamic Functional Connectivity (d-FC) and Dynamic Effective Connectivity (d-EC). Sliding window analysis (Bivariate Pearson correlation and Granger causality) and time varying parameter regression method (Flexible Least Squares) are two dynamic analysis strategies for time-variant connectivity analysis in the DynamicBC. Granger causality density/strength (GCD/GCS) and functional connectivity density/strength (FCD/FCS) analysis would be performed in this toolbox. Add DynamicBC's directory to MATLAB's path and enter "DynamicBC" in the command window of MATLAB to enjoy it.
The latest release is DynamicBC2.2_20181112
Manual could also be downloaded here.
New features of DynamicBC 2.0 release 20180311:
--Fixed minor bugs in the Clustering module.
New features of DynamicBC 2.0 release 20171228:
1. Changed the toolbox cover.
2. Added the new module for dynamic intrinsic brain activity (dynamic ALFF).
New features of DynamicBC 1.2 release 20160415:
Fixed the step bugs when selecting window size.
New features of DynamicBC 1.1 release 20140710:
1. Added the new utilties including the ‘Clustering’ and 'Spectrum' for dynamic FC/EC time series.
2. Added the new output of variance of dynamic FC/EC time series.
New features of DynamicBC 1.0 release 20140429:
This release fixed some minor bugs in dynamic FCD.
最近两天，用rest做functional connectivity 一直无法读入数据，添加数据后也是变绿色，但是就是不显示数据，请问这是怎么回事，谢谢。。
老师您好，我刚刚开始学习应用这些软件。看了您的视频教程，在用REST处理原始数据的时候，选择REST—UTILITIES__REST DICOM SORTER，选择文件之后，不在空白那里出现，点击RUN，之后就出现这个

那个后缀名三种都试过，IMA，dcm，none都是这样结果。后来直接用光盘里面的数据也是这样。请问老师这是哪里出错了呢？多谢老师指教
另外，如果不用rest批处理的话，还可以用什么软件做批处理的呢？
再次感谢老师指教
各位老师好，
我有一个关于三组病人单因素三水平方差分析FA的问题，考虑到年龄可能对白质改变起影响，所以就想在做方差分析的时候设年龄为协变量。之前试验性地比较了有无协变量情况的主效应，发现F-map还是不一样的。
首先，我不是很确定这算不算协方差分析。
其次，如果按照协方差的分析，前提需要满足年龄这个协变量与三组病人图像的回归系数，也就是斜率是一致的，才可行协方差分析。
第三，如果要评价三组病人图像跟各自年龄的回归系数，该在SPM里怎么操作？另外，如果三者的回归系数不一致，也就是说三条回归方程线有交叉，那我应该怎么处理年龄这个因素呢？
最后，如果在anova当中加了年龄做协变量，那么在随后的组间比较（事后分析）的时候，我还需要在T检验的时候加每两组的年龄作为他们的协变量吗？
不知道表述的清不清楚，问题有点繁琐，先谢谢各位老师啦~
