MATHEMATICA IMPORT/EXPORT FORMAT

HIN (.hin)

MIME type: chemical/x-hin
HyperChem HIN format.
Used in cheminformatics applications and on the web for storing and exchanging 3D molecule models.
Plain text tabular format.
Stores atomic coordinates, chemical bond information, and metadata.
Maintained by HyperCube, Inc.

Import fully supports HyperChem HIN files.

Import and Export Import and Export

Import["file.hin"] imports a molecule model or a structure diagram from a molfile.
Export["file.hin", expr] exports elements of a molecule model to a molfile.
Import["file.hin"] gives a list of Graphics3D objects when reading an HIN file.
Import["file.hin", elem] imports the specified element from a molfile.
Import["file.hin", {elem, sub_a, sub_b, ...}] imports a subelement.
Import["file.hin", {{elem₁, elem₂, ...}}] imports multiple elements.
The import format can be specified with Import["file", "HIN"] or Import["file", {"HIN", elem, ...}].
See the reference pages for full general information on Import.
ImportString supports the HIN format.

Elements Elements

General Import elements:

	"Elements"	list of elements and options available in this file
	"Rules"	full list of rules for each element and option
	"Options"	list of rules for options, properties, and settings

Graphics elements:
"Graphics3D" 3D renderings of the molecules in an HIN file

"StructureDiagram" 2D structure formula
Import by default uses the element HIN files.
Data representation elements:

	"EdgeRules"	connectivity data, given as an array of rules
	"EdgeTypes"	bond types, given as an array of strings
	"FormalCharges"	electric charges of the atoms, given as an array of integers
	"MassNumbers"	isotope mass numbers
	"VertexCoordinates"	3D atomic coordinates, typically given in picometers
	"VertexTypes"	all atoms or groups constituting the molecules, typically given as an array of chemical element abbreviations

Options Options

General Import options:

ImageSize	Automatic	specifies the overall size of the graphics to display
Background	White	specifies what background color to use
ViewPoint	Automatic	point in space from which the 3D model is to be viewed

With the default setting "ViewPoint"->Automatic, Mathematica automatically calculates the optimal viewing angle for the imported molecule geometry.
Selecting a 3D rendering style:
"Rendering" "BallAndStick" specifies the visualization method
Possible settings for are:
