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.
