DPABI output- ROIsignals.text differences

Dear Experts,
I re-ran 2 subjects through DPABI using the same parameters and ROIs that I used for the same two people that I ran as part of a larger group ( n=50).
When I compare the output folders FunImgARCFWS_ROISIGNALS/ROISIGNALS_subjectx of the same person, the ROI time courses look very different, even though I used the same parameters as before.
Would you know why that is? I can only imaging that in my prior analysis these two subjects were run as part of a different group? Does the ROISignals .text output gets normalized according to the included subjects?

error when use Permutation test

严老师好,

我这用dpabi做FC与行为学的相关的时候出现了如下报错,应该如何处理?

我使用的dpabi版本是V3.1, MATLAB2017,WINDOWS 系统。

 

ANOVA报错与Mask问题

1. 使用Dpabi中的统计分析进行ANOVA分析比较三组的FC差异
事后比较选择Tukey检定,正常的F.nii可以正常生成,但是事后比较出现付图的报错
后来有试着运行其他事后比较,Tukey和雪费都会报错但是Dunnet和Bonferroni可以运行,请问是下列报错是哪些地方操作错误了呢?
2.教学影片中有提到如果欲使用AlphaSim或是GRF等校正,需要选取MASK档案,但是我不知道这个Mask档案应该在哪个目录下,Masks目录下的AllresampledBrainMask没有任何内容又是正常的吗?
感谢老师的答覆

the criterion of remaining subjects,afeter scrubbing

Dear all,

I want to use the data preprocessed to do the later analysis such as build a martix. But some subjects has limited timeseries when I finished scrubbing,which may result in a strange result. So I want to know how many time timeseries left in a subject( for my case ,the total time series are 180,first 5 were revoved at the very beginning part) is enough for further analysis.

Sincerely,

Lin
