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 using y_ExtractROISignal (line 239)

I have 3 groups of subjects, and I am using a ROIList.mat file for all 3 groups. It works without issues for 2 groups. For the third, it gives below error. What does it mean?-

An UndefinedFunction error was thrown on the workers for 'MaskROILabel'.  This might be because the file


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.

something wrong when using mutiple comparation correction in dpabi

Dear all, 

I have troubling in using  the mutiple  comparation correction in stastical analysis in dpabi .  1.The pic1 shows the error when I was using PT with TECE . It still happened when I changed to the latest version of dpabi or using windows10 or mac system.

Normalize by dartel,what is the standard template?can i change it?

Hello pro Yan,

The article with data processed by dparsf was returned by the editor

And the reviewer asked us to re-do a rest-state analysis,and set the voxel size into 2*2*2 mm(3*3*3 previous by default) to map our activation analysis

Bur the results were strange and unreasonable

So i checked the normalize results,it seemed that i can not change the voxel size

Here are two normalized results for  one identical participate
