How to Post process the generated SIESTA output file to get the E-k in different directions .
My goal is to extract effective mass tensors that can be used for investigating elctronic properties.
The information already exists as all plots banndstructure, DOS etc is calculated from it,
But how to get four columns kx,ky, kz and corresponding E for conduction and valence band to quantitatively evaluate the effective mass tesnors
