Dear Akshu, What Jin has mentioned is totally right. Indeed, to make a better agreement with the transmission peak, you can include some neighbouring electrodes atoms. Furthermore, these atoms are not necessarily successive.

Re: [SIESTA-L] Non equilibrium density of states in Transiesta
Dear Jin and Akshu, The code has moved the Fermi energy to zero. That is to say the smallest positive eigenvalue is LUMO and the biggest negative one is HOMO. To obtain wavefunctions for HOMO/LUMO and visualise them, you should use EigenChannels in inelastica package, which is also a free one. EigenChannels can read TS.TBT.PDOSto' and TS.TBT.PDOSFrom, and then calculated the eigenvalues and the eigenstates in a energy range. About Inelastica, you can download the code from http://sourceforge.net/p/inelastica/code/commit_browser. I now can not find the link on how to install and use this package. Maybe someone else can help on this.

[SIESTA-L] how to save EIG or PDOS at every step of MD run?
Any ready-to-use solutions? I really need to monitor not only the total energy but at least a bandgap at every step. Alex.
