Hi Ben,
to normalise yor fdt_network_matrix, you can divide each row by the respective entry in the waytotal file.
Hope this helps, cheers,
Matteo

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.
