Advice on converging a restricted open-shell DFT (rob3lyp/LANL2DZ) single point Gaussian09 calculation for a triplet spin-state molecule?
Before introducing solutions to solve this problem, let us analyze unnecessary keywords:
pop=full IOp(3/33=1) use=L506 does not affect the SCF convergence at all, ...

How to create an input file for band calculation
A general idea is:
Determine the crystal symmetry of your system.
Select the path between high symmetry points to calculate the bands (follow one of these links: 1, 2, 3 or read this paper).
Use a ...

How to select the projections and inner/outer window for Wannier90 calculations?
Notes on my answer: I'll mainly link to arXiv versions of papers, but will also link the peer-reviewed version if the arXiv page doesn't do that itself. DFA means "density functional ...

What is the best cell shape to calculate the energy of a free atom with a periodic DFT code (VASP)?
In the end, the OP did the following:
"take a unit cell of the bulk of that metal, calculate its energy and then divide it by the number of atoms in the unit cell. "
The question can stay ...
