Dear DPARSF users
I try to use DPARSF for my rest data but I face the following error which is related to Mask. I also chose NO mask to skip this step, but this error was appeared again. What should I do?
Hi,
Sorry to bother you frequently these days. An error occured after completing filtering and before nomalization (normalize with DARTEL). The same error happened with Matlab version 2014a and 2013b. The whole lines in the command window are as below:
Dear Colleagues,
I.
Would it be possible to implement calculation of a network homogeniety in the context of ReHo.. How would you do that? Would you just calculate KCC [Kendall's coefficient concordance] for all voxels within a given mask? (say, if we use Yeo's parcellation of major brain networks). Could you please suggest a function/script I can look into?

Hi
An error happened when I perform Bet using DPARSFA 4.1 . The Matlab command window gives some options to solve these problem, but I don't understand how to choose one option and continue processing. It reads as below in the command window:
Dear DR YAN
Hi:
I want to make a gray matter mask with GM probabilities greater than 20%. I've found there are brainmasks in REST, but I don't know whether they are gray matter masks or whole brain masks and what interpolating thresholds were used. Would you plese teach me how to make a Grey Matter mask by using REST or dpabi? Thanks a lot!
Hello,
I don't quite understand the conceptual difference between these outputs of the Functional Connectivity option. Both have as many rows as there are time points. Is it correct that "ROI_FCMap.txt" is the average correlation between the ROI and the rest of the brain at each time point and "ROISignals.txt" is the average activation of the ROI at every time point? Also are these numbers already z-transformed or not?
Thank you so much for your help!

Dear DPARSF experts
I face the following error. What should I do? (I use matlab 2015a and spm 12)
Dear experts,
I am new to DPARSF A and I would like to use this software to analyse resting state data from a series of subjects.
After having set all the parameters and prepared the data in the required way, I tried to run the software from the gui but I get the following error:
Hi,
just found out, that when using Dartel the Group mask as created with the GroupMask tool with DPABI shows holes, i.e. missing/empty voxels. The indivual wAutoMask-files for the subjects also have those holes.
Solution seems to be to smooth the wAutoMask files, which gets rid of the holes and the GroupMask looks fine thereafter.
Just something that can be considered in next releases :)
greetings
