I’m a novice to use Brain Connectivity Toolbox and trying to calculate topological measurements via it. I get an Inf value of characteristic path length when using the script.
(Actually, I also get Inf values in L variable.)
It works well for most subjects, but I get Inf values from some subjects.
Does anyone know how to solve this problem?
Command used (and if a helper script was used, a link to the helper script or the command generated):
W = CorrMatrix; % CorrMatrix is a correlation matrix consisting of 272 nodes across the whole brain. The correlations are not converted to Z values yet. W_nrm = weight_conversion(W, 'normalize'); W_thr = threshold_proportional(W_nrm,spa); L = weight_conversion(W_thr, 'lengths'); [D, B] = distance_wei(L); lambda = charpath(D);
