Dear DCM experts,
I am planning to run spDCM in two independent data sets using the same ROIs (networks) and a covariate of interest. I would like to assess the reliability of the effective connectivity results. The results are presented in heatmaps (like in the DCM output). My question is: Is there a way to directly compare heatmaps of two different samples? In other words, can I quantitatively assess the dissimilarity between heat maps given the fact that not each cell of the heat map contains a value?
For any suggestions on how to calculate a dissimilarity index in the context of DCM heatmaps would be highly appreciated.
Thanks a lot in advance.
Best wishes
Carmen
