Dear Dr. Yan,
Recently, I used y_CWAS.m to perform the CWAS analyis. I have several questions about the CWAS analysis.
[p_Brain, F_Brain, Header] = y_CWAS(DataUpDir, SubID, AResultFilename, AMaskFilename, Regressor, iter, IsNeedDetrend, Band, TR)
For the annotation of "Regressor", it said "the regressors, nDimTimePoints by nRegressor matrix".
Dr. Yan:
各位老师好，我是用DPABI里的friston24做的头动处理，请问一下headmotion里生成了一个矩阵，行我知道是被试，列有20列是代表什么呢？
另外如果想报告FD的话，报告哪个值比较好呢？POWER还是jenkinson？有没有报告的样板文献推荐？
Dear Prfo. Yan and Colleagues,
Hi! There are NaN in the results of Concordance_VolumeWise in some subjects. How can I solve this problem? Thanks!
Best wishes,
Lotus
老师，您好：
最近在用DPARSF分析一组数据，在处理步骤上存在一些疑问：
1.请问在做scrubbing的时候，勾选了Head motion scrubbing regressors后，还需要在后面勾选Scrubbing吗？
2.请问在采用不同mask计算功能连接矩阵的时候，需要事先将不同模板进行配准么？DPARSF有做相应的处理么？
3.如果想要一个mask一个mask的计算功能连接矩阵的时候，我们的starting Directory Name是选择FunImgARCWSF吗？
4.因为在计算前已经勾选了Smooth，在计算完指标后是否还需要进行Smooth Derivatives呢？
还望老师百忙之中可以给予解答，十分感谢！！
Hello,
I am doing second-level rsfMRI analysis with fALFF data in ~530 participants and try to use PT with TFCE for multiple comparison. I´have a very basic problem: I didn't understand which file/folder to chose for 'Group Images' at the section statistical analysis of DPABI Toolbox.
I've already check the slides, which don't mention about input.
rfmri.org/content/permutation-test-dpabi website also doesn't give the clue.
Should I use fALFF maps? I would be happy to hear the right way to do it, before MATLAB would be unresponsive for hours..
老師您好!
想和您請教一下，
我的實驗設計是同一批人，在某一天做一特定介入的介入前以及介入之後的靜息態腦影像掃描(兩組掃描)，另外一天換成另外一項不同的介入，但是一樣是做介入前以及介入之後的靜息態腦影像掃描(另外兩組)
這樣的實驗設計，希望去分析比較全腦ReHo在兩種不同介入之後的差異，
(1)應該是以Paired-t test分別去比較兩天介入後減前的結果去解釋即可。另外，如果想證明不同天的介入前Baseline有無差異，則做兩天的Baseline之Paired-t test (如果這些結果均經過GRF correction，是否即可避免type I error?)
(2)或是應該做Mixed Effect Analysis 或是 ANCOVA 去分析4組數據的差異呢?
