 7Introduction
 8============
 9
10TURBOMOLE_ is a density-functional or Hartree Fock code using 
11atom centered orbitals. This 
12interface makes it possible to use TURBOMOLE_ as a calculator in ASE.

18Environment variables
19=====================
20
21Set environment variables in your configuration file:
22
23- bash::
24
25  $ TURBODIR=/my_disk/my_name/TURBOMOLE
26  $ PATH=$TURBODIR/scripts:$PATH
27  $ PATH=$TURBODIR/bin/sysname:$PATH
28
29- csh/tcsh::
30
31  $ setenv TURBODIR /my_disk/my_name/TURBOMOLE
32  $ set path=(${TURBODIR}/scripts $path)
33  $ set path=(${TURBODIR}/bin/sysname $path)
34
35where `sysname` could be, e.g.: `x86_64-unknown-linux-gnu`.

37Turbomole Calculator
38==================== 
39
40All usual turbomole input files generated by Turbomole's define 
41[coord, control, basis, (auxbasis), 
42mos/alpha+beta] must be present in the current working directory. 
43
44Turbomole files are updated during the ASE-run. 
45
46Do not use internal coordinates, only cartesians are allowed.
47
48Ase-Turbomole uses turbomole programs 'ridft' and 'rdgrad' 
49if keyword '$ricore' is present in the Turbomole's control file. 
50Otherwise programs 'dscf' and 'grad' are used.
