Hi Mite,
Thank you for taking the extra effort to help with the analysis. I have sent you an email.

Hi Mite,
I was wondering if you had time to think about my query, on how to proceed from the group DCM to graphs. If the estimated effective connectivity matrix from DCM can be interpreted as a weighted adjacency matrix of a directed graph between the brain regions. For the Braph pipeline implementation, the group DCM could be treated as a single…[Read more]

Hi Mite,
Thats great! Thank you.
We want to analyse the graphs and its metrics using the full ABC connectivity matrices.
I have a basic question about using the matrices for each subject, would it be possible to just use the (single) group level ABC matrices for the graph analysis?
The reason I ask is because in our DCM analysis we did not…[Read more]

Hi Mite,
Thank you for the information and help.
Since I am short on time to perform the graph analysis (for a revision), I can implement the pipleine for the analysis, with your help.
I downloaded the latest version of Braph 2 from the repository. From its folders I can see that the code for graph metrics and analysis is already there.
To…[Read more]

Dear Braph Community,
My question if about using graph analysis on fMRI data. I performed an effective connectivity analysis using DCM and have connectivity configurations in terms of A,B and C matrices. I am wondering if I can now use a graph analysis on the DCM matrices to obtain graph metrics of the node interactions and a formal graphical…[Read more]
