wavespectra.SpecDataset.to_octopus

SpecDataset.to_octopus(filename, site_id='spec', fcut=0.125, missing_val=-99999, ntime=None)

Save spectra in Octopus format.

Args:

• filename (str): name for output OCTOPUS file.

• site_id (str): used to construct LPoint header.

• fcut (float): frequency for splitting spectra.

• missing_value (int): missing value in output file.

• ntime (int, None): number of times to load into memory before dumping output file if full dataset does not fit into memory, choose None to load all times.

Note:

• dataset needs to have lon/lat/time coordinates.

• dataset with multiple locations dumped at same file with one location header per site.

• 1D spectra not supported.

• ntime=None optimises speed as the dataset is loaded into memory however the dataset may not fit into memory in which case a smaller number of times may be prescribed.
