Hi, I am receiving the following error trying to complete standardization:
??? Out of memory. Type HELP MEMORY for your options.
Error in ==> var at 87
y = sum(abs(x).^2, dim) ./ denom; % abs guarantees a real result
Error in ==> std at 32
y = sqrt(var(varargin{:}));

Dear experts,
Recently I just tried using the DPARSF v4.1 to preprocess my resting fmri data, but somehow always could not finish it, reminding the mistake in time point when maybe last step to normalize. Strange thing is I specially checked all the data, there is no wrong in FunRaw. So I am totally confused. Below I showed some screenshots with the template parameters I set and some details of the mistake that Matlab warned.
Best regards,
Xin
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:
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.
Hi! I am getting the following error at the automask step and I am wondering how to proceed?
