Hello, I am new to the igraph package, and I am trying to analyze EEG coherence data. These data is based on the phase relation between electrode signals, and I currently have adjacency matrices for every participant in my sample, which are 128 x 127 matrices of correlations between all the electrodes. I understand the general language of igraph once the graph object itself is created, but I am having some trouble setting up so I can make the object. I am writing to ask for help on: 1) How do I read in all my matrices (1 per participant, total of 177 participants) and create a graph object? 2) Would the graph object be based on the average of all these matrices? 3) How would I go about including the map of where the electrodes go on the scalp?
Thank you, Berenice _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
