Supported file formats

sire supports reading and writing to many common molecular file formats. You can print the list of supported formats using

>>> print(sr.supported_formats())

Symmetric Input / Output

One of our design principles is that molecular file input and output is symmetrical. This means that sire can read in and write out the same amount of information from a file (i.e. it can always read what it writes).

Another design principle is that information should not be lost. As much as possible, sire will load and preserve all information it can read from a molecular file.
