SEED and miniSEED converters user guide ​

TIP

This guide describes applications that convert either SEED or miniSEED volume to SAC, ASCII or miniSEED (for conversion from SEED to Network Inventory see this guide), optionally allowing for removing response or converting to different units. These applications are:

  • miniSEED to ASCII converter,
  • miniSEED to miniSEED converter,
  • miniSEED to SAC converter,
  • SEED to ASCII converter,
  • SEED to miniSEED converter,
  • SEED to SAC converter.

To obtain more general information about working with applications within the Platform, see Applications Quick Start Guide.

Input file specification ​

SEED converters ​

SEED converter applications require one or more files of type Seed Waveform (or any subtype).

Figure 1. SEED converter input file specification.

miniSEED converters ​

miniSEED converter applications require one or more files of type Miniseed Waveform (or any subtype), additionally a Network inventory file can be supplied, to enable response removal or other more advanced conversions.

Filling form values ​

Depending on the type of the converter and the provided inputs, the application form may contain the following fields:

  • Remove response - choose wether you want to remove response. For details related to the response removal, please consult the ObsPy Documentation. The option is available only for (full) SEED file converters and for miniSEED converters if the Network Inventory is provided.
    • Zero Mean - choose wether you want to correct the baseline.
    • Filter parameters - apply a bandpass filter in frequency domain to the data before deconvolution. The list or tuple defines the four corner frequencies (f1, f2, f3, f4) of a cosine taper which is one between f2 and f3 and tapers to zero for f1 < f < f2 and f3 < f < f4.
    • Convert to - choose output units - acceleration (output unit is meters/second[^2]), velocity (output unit is meters/second), displacement (output unit is meters).
  • Output format - in case of conversion to ASCII format, choose the concrete ASCII format in which the output file will be written (specification of the formats is available in ObsPy Documentation. The option is available only for SEED and miniSEED to ASCII converter applications.
  • Write result to single output file - Write result to single output file rather than creating one file for each signal. The option is available only for converters to miniSEED format (it is default for those converters).

Produced output ​

The result of the application is the converted file or a set of files. If the Write result to single output file option was chosen (only for conversion to miniSEED), the name of the result file will be a slight modification of the input file. Otherwise, there might be multiple files returned, each containing the ID of a converted trace from the initial file.
