What is D_ATAΒΆ
D_ATA program
In Chemistry, the non-chemical function and behaviour of all molecular materials are underpinned by the strength and directivity of the constituent inter-atomic interactions. D_ATA is developed to identify these interactions, and from such, to classify, annotate and quantify them to provide statistical and structural information of a molecular systems.

Functions
D_ATA (DL Atom Typer and Analyser) is the product combination of two unique features implemented in DL_FIELD and DL_ANALYSER respectively:
DL_F Notation - A standard notation to describe chemical identity of an atom.
DANAI - A language construct based on DL_F Notation to describe localised atomic interactions.
From such, D_ATA
Identify and classify types of non-bonded interactions.
Quantify interactions and carry out analysis.
Calculate order parameters or geometrical analysis for different modes of interactions.

Capabilities
Read user configurations in PDB, xyz and Gromacs gro (configuration) formats.
Distinguish interactions that occur either within (intra-) or between (inter-) molecules.
Can detect HB and HP interactions.
Investigate topological interacting structures by measuring linearity and triangular order parameters
Detect interactions involving atoms from up to two different Chemical Groups.
