Unable to run subgraph analysis

[johnsojp]

Hello BRAPH team,
I can’t seem to run subgraph analyses on my data and I am unsure why. I set up a weighted undirected graph with pearson correlations and I am including negative correlations (however, I have also tried setting negatives to zero and I get the same error described below when I try to run subgraph analysis). Just in case it’s relevant, I entered my subject-level data as correlation matrices (as described in another forum post) rather than timeseries data.

I set my community structure based on one group of participants by entering the community structure window, selecting Newman algorithm, gamma = 1, and clicking “Calculate”; then I checked “Fixed structure”, clicked “Set”, and closed the community structure window. I next opened the Subgraph analysis window, selected the first module (module1), clicked “set” and then “start analysis”, which returned the following error in matlab:

Matrix dimensions must agree.

Error in GUIfMRIGraphAnalysis/update_matrix (line 714)
A = A+ga.getA(indices(i));

Error in GUIfMRIGraphAnalysis/setup (line 1204)
update_matrix()

Error in GUIfMRIGraphAnalysis (line 1188)
setup()

Error in GUIfMRIGraphAnalysisSubgraph/cb_menu_ga (line 575)
GUIfMRIGraphAnalysis(subgraph)

Error using GUIfMRIGraphAnalysis/cb_calc_sub (line 483)
Error while evaluating UIControl Callback

Can anyone provide some guidance on what’s going on here and how I can fix it?

Thank you very much!

Jeff
