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 The dimensions of the arrays in the tables below are given in
column-major order (as in Fortran), and the ordering of the dimensions column-major order (as in Fortran), and the ordering of the dimensions

In Fortran, the arrays are 1-based and in most other languages the 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
