Hi Vardan, This information is stored in the scattering matrix in the lead_info attribute (see https://kwant-project.org/doc/1/reference/generated/kwant.solvers.common.SMatrix#kwant.solvers.common.SMatrix) in the format described here: https://kwant-project.org/doc/1/reference/generated/kwant.physics.PropagatingModes#kwant.physics.PropagatingModes
