TR一致,Time points不一致的数据可以比较吗?

各位老师,请问TR一致,Time points不一致的影像数据可以比较吗?比如Alff,Reho,DC,用他们的Z值图可以直接contrast吗?

mask for statistical analysis

Dear all,

In the statistical analysis, we need to choose a binary mask.

What kind of binary masks I can apply? If I turn to the group-wise GM mask, it seems there're too many comparisons, leading to failure in the tfce+fwe correction (p<0.05).

Can I use the |Z|>2 of the Z map as the binary mask instead to reduce the number of comparisons?

 

Thanks!

 

REST-meta-MDD excluded subjects

Dear Experts,

Thank you very much for providing the REST-meta-MDD data in such a usable format to the community.

I have been working with this data and I have noticed that in your reference paper (https://www.pnas.org/content/116/18/9078) several subjects have been excluded because of image quality issues (bad data, bad normalization, bad masking, etc.).

I was wondering if there is a list available somewhere of these participants with problematic data, so that they can be excluded without having to reinspect the whole dataset.

Thank you very much.

DPARSF Cov_regression produces weired images

Dear Dr. Yan,

I am using DPASFA v4.3 to run resting-state image, within the step : ARSWDCF. The detrended images are good, but something goes wrong after the regression.  Bellowing are the settings I used, the Detrended image, and Detrended + Covregessed .  If I put the cov_regressed images into ICA, it will produce even more weird results.
