This page contains information about the general structure of the
TREXIO library. The source code of the library can be automatically
generated based on the contents of the ~trex.json~ file, which is
compiled from different sections (groups) presented below.
All the quantities are saved in atomic units.
For more information about the automatic generation on the source code
or regarding possible modifications, please contact the TREXIO developers.
All quantities are saved in TREXIO file in atomic units.
The dimensions of the arrays in the tables below are given in
column-major order (as in Fortran), and the ordering of the dimensions
is reversed in the produces JSON configuration file as the library is

In Fortran, the arrays are 1-based and in most other languages the
arrays are 0-base. Hence, we introduce the ~index~ type which is an
arrays are 0-based. Hence, we introduce the ~index~ type which is an
1-based ~int~ in the Fortran interface and 0-based otherwise.
