Dear Dr YAN

i hope you do will.

1-Video is very  fantastic ,but really i want reference for thioretical information of clusters.

2- if i have this cluster:

Dear experts,

I have a question about the paper "Cluster failure: Why fMRI inferences for spatial extent have inflated false-positive rates" and Cox's paper  "AFNI and Clustering: False Po

各位大大，请教关于在Rest的工具里做Alphasim 矫正：

Hi, I want to apply GRF-correction on my data and am insecure what to type in the GRF-box in DPARSF:

Hi, I have 2 questions.

First, How can I extract only grey matter voxel signal?

I extracted 116 ROI region signal applied by AAL mask, but I need voxel-wise information.

I knew that functional information comes from grey matter, so I'm gonna extract all voxel signals in grey matter.

Second, I don't know how I can start the point where I have done processing so that I shouldn't do again what I had done.

I tried to uncheck the menu which I have done, but I don't know how I can write 'starting working directory'.

Dear Dr YAN

please i want to read about clusters,i need to know every thing about(cluter size ,peak in cluster and custer report)

and i have question if i save all cluter does the cluter report return all activated regions for all slices?

thanks for your help.

Dear Dr YAN

please i do the two sample ttest like this

i do that without covariate images , my question it is right or no?

if the covariate images necessary?

if necessary i want to know what these effect and from any files of dpabi output can i get them?

thanks for your help.
