Dear Expert,
I would like to know if it's possible to calculate eigenvector centrality with DPARSF. At the moment only Degree Centrality calculation is available.
Thanks in advance for your help.
Best regards,
Enrico Premi, MD

Re: Eigenvector Centrality
Dear Enrico
I'm not sure that this is the answer you're looking for, but I have made a small matlab program with a simple GUI that computes eigenvector centrality maps from 4D fmri data sets. If you download the zip file [ https://code.google.com/p/bias/downloads/detail?name=fastECM.zip ] and follow the instructions on the website, then it should be very simple to install and use.
The methods are described in this paper [ http://online.liebertpub.com/doi/abs/10.1089/brain.2012.0087 ].
The maps contain normalised centralities (ie the sum of their squared intensities equals 1). It is also possible to construct maps that have uniform ]0,1[ and N(0,1) distributed intensities.
If you have any further questions please let me know.
With best wishes
