GWF file I/O (`gwpy.io.gwf`)#

I/O utilities for GWF files.

Most of the actual GWF file I/O is delegated to one of the ‘backend’ implementations that rely on a third-party library.

Functions#

`channel_exists`(gwf, channel[, backend])	Determine whether a channel exists in a GWF file.
`data_segments`(paths, channel[, warn, backend])	Returns the segments containing data for a channel.
`get_backend`([package, backends])	Return the preferred GWF backend.
`get_backend_function`(name[, backend, ...])	Return the backend implementation of the function of the given name.
`get_channel_names`(gwf[, type, backend])	Return a list of all channel names found in a GWF file.
`get_channel_type`(channel, gwf[, backend])	Find the channel type in a given GWF file.
`identify_gwf`(origin, filepath, fileobj, ...)	Identify a filename or file object as GWF.
`import_backend`(library[, package])	Utility method to import the relevant GWF I/O backend.
`iter_channel_names`(gwf[, type, backend])	Iterate over the names of channels found in a GWF file.
`num_channels`(gwf[, type, backend])	Find the total number of channels in this GWF file.

Preferentially ordered list of supported GWF backends.
