Dear Artem, you already got a very exhaustive answer, but I like to add couple of remarks as I find these points of interest. On 04/25/2013 07:14 PM, Artem Baskin wrote: > Dear SIESTA/TRANSIESTA users, > > I have recently read the paper (PRB 81, 205437) and found it very > interesting and enligh

use any plotting utility, I'm sure Ubuntu is plenty of stuff like that. If you don't know where to start from, give a look to xmgrace ( http://plasma-gate.weizmann.ac.il/Grace/), which should be in Ubuntu repositories.
