Hi,
I extracted the ROI time courses via DPABI and specified the AAL atlas. This gives me a of ROI correlation matrix as mat-file for every test subject. But how to determine the significance of the correlations between ROI's on a group level, i.e. if a correlation is significant over all test subjects?
Dear Dr.Yan,
Could I bother you a basic question ? When I was doing ALFF, the mask should be the graymask I made based on the subjects, or be the one-sample t-test? Because the result between the two methods is a little different. The second question is that if I regress out the graymatter volume from the alff, what the mask should I put into?

Dear Prof Yan,
I came across an error when computing CWAS. Here is the error message:
Hi all.
I'm kind of new in DPARSF and I'm having trouble doing normalization with T1 image unified segmentation. after reorienting the images. somehow dcm2nii is called, I have my nifti T1 images and I unchecked T1 dicom to nifti. here's my workspace:
Hi, all,
In the latest released version of Dpabi, I found two templates, named as "CC200ROI_tcorr05_2level_all.nii" and "CC400ROI_tcorr05_2level_all.nii" in the path of "DPABI_V1.3_150710\Templates\". Considering their advantage of numerous ROIs, I would like to use them. However, I have no idea about any more info about these two templates. Can anyone tell me where they are from and how these ROIs are defined? Also, it would be highly appreciated if someone can provide me with the related reference materials or papers. Thank you for your favorable reply in advance!
Dear Experts
I have few questions:
I'd like to use AlphaSim to obtain the minimum cluster-size (for multiple corrections) for my ROI analysis of ppi, and done the following:
I wonder if these are correct.. Could you clarify my mistakes?
Hi
I would like to correlate the connectivity parameters with covariates eg Ratings. I extracted ROI signals by defining different ROIs and get zFCMaps. Which parameters/values of the output do I have to use for correlations?
Thanks

Hi,
I just wanted to note, that when using the Threshold motion and EPI Coverage tools it does not show the standard deviation (see pictures attached). What could the problem be and how to fix it :)?
I'm using Windows 7 with Matlab2014a and SPM12 with the latest version of DPABI (V1.3_150710)
greetings
