Several new features and many improvements now make the R.I.N.G.S. code more reliable and efficient:

- New distribution functions are available: total
**G**(r) and partials**G**_{αβ}(r) - X-rays structure factors are now computed
- Several distribution functions are now computed both for the simulation of neutrons and X-rays diffraction: T(r), D(r),
**g**(r),**G**(r) - The distributions of dihedral angles are now computed
- The average proportion of the diffrent chemical species in the rings can be evaluated during ring statistics

- Correction of several bugs

The R.I.N.G.S. code is written in Fortran90 and is about 27000 lines of instructions long (with 200 subroutines and 2 modules).

The memory allocation and deallocation processes are mostly dynamical.

Furthermore the code is fully parallelized using the Message Passing Interface, 'MPI' with a fully unblocking scheme.

When studying amorphous systems ring statistics are mainly used to obtain informations inaccessible using standard tools such as the radial distribution functions or the neutron structure factors.

In particular it allows to scan the network at a farther scale than the first or the second coordination shell. Thus it is possible to obtain informations on the intermediate Range Order 'IRO' of the material.

For instance it is well known that in glass science finding the origin of the disorder and understanding the origin of the IRO is a key for the interpretation of the optical and conduction phenomena.

In this context using the ring statistics techniques appears to be fully justified.

In this context we have developed the R.I.N.G.S. code to implement and compare the different possibility to classify rings existing in the literature [a, b, c, d, e, f].

Nevertheless precise informations can not be obtained without using an accurate method.

In the R.I.N.G.S. code we have implemented an original method to analyze the connectivity of a topological network using ring statistics [h].

This method allows to obtain the connectivity profile of the network and then to study and compare with efficiency the connectivity of different networks using ring statistics.
