Input/Output (

Available files for reading/writing

sisl handles a large variety of input/output files from a large selection of DFT software and other post-processing tools.

Since sisl may be used with many other packages all files are name siles to distinguish them from files from other packages.

Basic IO methods/classes

add_sile(suffix, cls[, case, gzip])

Add files to the global lookup table

get_sile(file, *args, **kwargs)

Retrieve an object from the global lookup table via filename and the extension

SileError(value[, obj])

Define an error object related to the Sile objects

External code in/out put supported

List the relevant codes that sisl can interact with. If there are files you think are missing, please create an issue here.

Low level methods/classes

Classes and methods generically only used internally. If you wish to create your own Sile you should inherit either of Sile (ASCII), SileCDF (NetCDF) or SileBin (binary), then subsequently add it using add_sile which enables its generic use in all routines etc.


Retrieve all files with specific attributes or methods

Retrieve a class from the global lookup table via filename and the extension


Base class for all sisl files
