Dear Pro. Yan

I would like to ask a question about the Rest toolbox.

Our purpose is to calculate the Reho value in 35 voxels and 50 voxels using the Rest toolbox, rather than in 7, 19 or 27 voxels each cluster.

Can we change the number of the voxel by modify Reho.m file? If can, how to do that?

Thank you very much.

Dear prof.,
There is an error shown below, could you help me? Thanks a lot.

Hey,
I generated a 90% group mask and wanted to use the threshold coverage function to exclude subjects which have coverage less than 2*SD under the group mean overlap, like mentioned in the videos. The wAutoMask.nii files are all there, but the script seems to want a nii.gz file, because after selecting the group mask I get the following error:

Dear DPARSFA experts, dear Chao-Gan I just started using the DPABI toolbox (Btw, thanks for the excellent software!) and ran into a problem when using DPARSF 3.1 to compute a functional connectivity analysis. I pre-processed my resting state EPIs using SPM5 (the data has been checked for quality and should be fine) and then switched over to SPM8 to be able to use the DPABI toolbox. I have one seed ROI (a 6mm sphere approximately covering the right ventral striatum; MIN-coordinates: 9, 6, -8) and 56 subjects.

Dear Chao-Gan, Just a real quick question. I ran the Automask in 100 subjects during which no error message had shown. However, all the auto masks I got are white boxes, like this: [image: Inline image 1] Is it normal or not? I am totally confused. Thank you very much!

I am sorroy for so many questions I have. But I am stuck. I see a lot of Templates in DPABI. Could you please introduce the "WhiteMask_09_91x109x91",What is the probability of it? And what is the differents between "GreyMask_02_61x73x61" and "BrainMask_05_61x73x61"?

When I applied AlphaSim in dpabi. I found the default Cluster connection radius is 18, which is different from AlphaSim in REST (rmm=5). Is something wrong or both of them are correct?
