calculate functional connectivity in new ROIs after dpabi calculation

Submitted by JungLungHsu on Sat, 01/30/2016 - 07:42

Dear Prof.

I am new in using dpabi and have 2 questions

1. after I define AAL ROI and finish dparsfa process, then I try to calculate a new function connectivity between new ROI_1 and ROI_2, could you please tell me how to do that ?

2. I use Matlab2012a in CentOS6.5 and latest version of dparsfa, when I run the process, every thing is ok but I finally get error message:  what I can do ?

thanks help

Hi,

1. You can remove the defined ROIs and add the new ROIs. Or you can reopen Utilities->ROI Signals Extractor or DPARSF to extract the signals of new ROIs.

2. Could you check what kind of files are under /home/tulu/fmridata/FunImgARglobal/04263040?

Best,

Thank your answer. I find the error about second question, I don't build the FunImg folder and I start from Nifti file, so there is no FunImg folder for further process.


May I ask a quesion ? when I calculate the DMN functional connectivity, is there a index to represent the whole network activity rather than ROI_1 and ROI_2 connectivity ? how to calculate a network activity which may contain 7 or more regions ?


thanks

Seems it didn't create the symbolic link of FunImgARglobal.

You can test if the command ln works in your linux.

For the second work, you can try dual regression. Which is available in the developing verstion: https://github.com/Chaogan-Yan/DPABI
