## A smooth and fast interface

archeofrag gui is a convenient interface to perform a complete analysis of a refitting dataset. It offers:

* an integrated **workflow** supported by detailed documentation,

* **anomaly detection** in the spatial distribution of refitting connection,

* research of relevant spatial units **merging**,

* easy **simulation** setup and execution,

* **code** generation:

- in R: to reproduce the simulations executed in the application,

- in openMOLE language: to use with the related platform,

* figures and tables **export**.

## Simulating site formation scenarios

Complete simulation of site formation process raises complex computational issues and requires advanced methods and high-performance computing. The *archeofrag gui* workflow draws on the model exploration methods implemented in the (open-source) *openMOLE* platform. In particular, the use of the 'High Dimension Origin Search Exploration' (HDOSE) method makes it possible to **estimate** the **initial conditions** of an archaeological site:

* the initial number of (non-observed) objects and fragments,

* the number of deposition events, and

* the direction of fragments transport between spatial units, in particular.
