The Apply operator module convolves a user-supplied wavelet or filter operator with every trace in the input seismic gather. The convolution is centered on the operator, meaning the operator is correctly aligned in time relative to each trace before the convolution is performed. The result is written to the output gather, leaving the trace geometry and header information unchanged.
Use this module whenever you need to apply a shaping filter, deterministic wavelet, or any single-trace operator to a dataset. Typical applications include wavelet shaping, phase correction using a precomputed operator, and convolution-based noise suppression. The wavelet operator must contain exactly one trace, and its sample interval must match that of the input gather.
The seismic dataset to be processed. This connection carries the input seismic gather (Input gather) together with the associated trace headers and data handles from the upstream processing node. All traces in this gather will be convolved with the wavelet operator. The sample interval of the input gather must be identical to that of the Wavelet Operator input.
The current seismic gather passed gather-by-gather through the processing sequence. Each gather is convolved independently with the wavelet operator. This item is populated automatically from the Input DataItem connection and does not require separate configuration.
The operator to be applied to the seismic data. This must be a gather containing exactly one trace, which represents the wavelet or filter kernel. The operator is convolved with each input trace in a centered fashion, so that the reference time of the operator aligns with each sample of the trace during convolution. The sample interval of this operator must match the sample interval of the input gather exactly; the module will report an error if there is a mismatch. Connect this input to a gather item that holds your precomputed shaping filter, matched filter, or deterministic wavelet.
This module has no user-configurable parameters. The convolution is performed automatically using the connected Wavelet Operator. All processing behaviour is controlled solely by the content of the input data items.
