Hello FSL Experts,
I've generated a connectivity matrix of 78x78 using the fdt_network_matrix output from probtrackx2. Because my ROIs are unequal size, I want to normalize the results by dividing by the waytotal. However, the waytotal file is 78x1, not 78x78. I'm unsure if I should divide along columns or along rows. In other words, for the first number in the waytotal file, do I want to divide every number in row 1 of fdt_network_matrix by that value, or do I want to divide every number in column 1 of fdt_network_matrix by that value? The matrix is not symmetrical about the diagonal so these would produce different results.
Thank you!
-Ben
