Thanks, Bartek!
So trial SIESTA run doesn't seem to be the best way to produce initial
coordinates file.
Hello, let's share our methods of constructing initial coordinates for
SIESTA.
There is a lot of atomic structure apps under linux, but I didn't find
anything better than use *.car format and then copy/paste its content into
input.fdf with following manual edit. It is not very comfort, especially
Thank you very much.

Hi Magda,
For a given k-point, the bands file will have spin up and spin down entries if
the run was spin-polarized. To see where the spin down entries start, look for
a sudden jump in the eigenvalues (ie, from large positive values back to
negative ones) right at the middle of the dataset for
I have performed Spin Polarized calculations. I would like to know how can I
turn on spin down calculations in the file *.bands
Thanks in advance

Hi Everyone,
Thank you for your quick responses.

These are different, but related. issues:
BSSE is an error that comes from the incompleteness of atom-centred basis sets.
Basically, if you add atoms, you add basis functions. If you move atoms closer
together, they can use each other's basis functions, which "improves" the
basis. The result is an

If I am not mistaken, STRUCT_OUT file is created *after* completing at
least one CG or MD step, i.e. after SCF has conver
