Hi

I would like to correlate the connectivity parameters with covariates eg Ratings. I extracted ROI signals by defining different ROIs and get zFCMaps. Which parameters/values of the output do I have to use for correlations?

Thanks

Hi, 

I got the following errors during running "Calculate variables and export". I would appreciate if you could help me fix these errors.

Hi,

I just wanted to note, that when using the Threshold motion and EPI Coverage tools it does not show the standard deviation (see pictures attached). What could the problem be and how to fix it :)?

I'm using Windows 7 with Matlab2014a and SPM12 with the latest version of DPABI (V1.3_150710)

greetings

Dear developers and users,

Hi everyone,

Dear all, 

I was wondering about the possibility to extract a specific ROI signal of the ZROIxFCmap (resulting from the FC) and then correlations with different questionnaires.

Is it a good approximation???

Thank you once again!

Hi,

It is well-known that depending where we choose seed region of the DMN (e.g.., PCC or mPFC) we can get major difference between the networks. Why is that? If region A was correlated with region B, then it does not matter which of them was seed. Is it because the network we get is a statistical map? So, for example, the most strong correlation of A is with B. But B, has stronger connection with C. So, the when A is a seed I will see the B. But When B is the seed I will not see the A. 

Hello

When I try to run the "Network Calculations" section of GraphVar by clicking on the "Calculate variables and export" button, it seems to do the calculating just fine, but then gives this error (copied below) when it goes to export.  I haven't had any problems with the Statistics or correlations portion on this dataset, just this section for basic network calculations.  It doesn't seem to matter what metric I'm using.

I've included a screenshot of the things that I've selected in the GUI.

Thanks!

Dear all,

We have noticed that if .hdr/.img T1 images were used for segmentation, DPARSF_V3.2_150710 reports an error of "File too small".

We have fixed this error, please use the attached file to overwrite the existing one in DPARSF_V3.2_150710.

Hi,

I am new in fMRI and the associated tools and I would like to ask a very entry level question.

I am using the HCP database subjects and trying to get time courses for specific voxels. Now I have ther voxels in MNI coordinates. (an excel file containing many voxels identified by x,y,z coordinate).

eg:
