openquake.hmtk.parsers.strain.strain_csv_parser module

Module: openquake.hmtk.parsers.strain.strain_csv_parser contains the :classes: ReadStrainCsv and WriteStrainCsv to read and write strain data from and to csv format.

class openquake.hmtk.parsers.strain.strain_csv_parser.ReadStrainCsv(strain_file)

Bases: object

openquake.hmtk.parsers.strain_csv_parser.ReadStrainCsv reads a strain model (defined by :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain) from a headed csv file

Parameters:

• filename (str) – Name of strain file in csv format

• strain – Container for the strain data as instance of :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain

read_data(scaling_factor=1e-09, strain_headers=None)

Reads the data from the csv file

Parameters:

• scaling_factor (float) – Scaling factor used for all strain values (default 1E-9 for nanostrain)

• strain_headers (list) – List of the variables in the file that correspond to strain parameters

Returns:

strain - Strain model as an instance of the :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain

class openquake.hmtk.parsers.strain.strain_csv_parser.WriteStrainCsv(filename)

Bases: object

openquake.hmtk.parsers.strain_csv_parser.WriteStrainCsv writes a strain model (defined by :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain) to a headed csv file

Parameters:

filename (str) – Name of output file for writing

slice_rates_to_data(strain)

For the strain data, checks to see if seismicity rates have been calculated. If so, each column in the array is sliced and stored as a single vector in the strain.data dictionary with the corresponding magnitude as a key.

Parameters:

strain – Instance of :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain

Returns:

strain - Instance of strain class with updated data dictionary output_variables - Updated list of headers

write_file(strain, scaling_factor=1e-09)

Main writer function for the csv file

Parameters:

• strain – Instance of :class: openquake.hmtk.strain.geodetic_strain.GeodeticStrain

• scaling_factor (float) – Scaling factor used for all strain values (default 1E-9 for nanostrain)
