General

The General category collects a broad set of utility and workflow-management modules that support every stage of seismic data processing. These modules are not tied to a single processing discipline — instead they provide the building blocks needed to construct, control, and automate processing flows, manipulate data items and trace headers, handle files and tables, and perform common signal-conditioning tasks that arise throughout a project.

Modules in this category fall into several functional groups:

Flow control and looping. The Flow, Seismic flow, Loop, Seismic loop, Seismic distributed loop, If, and Recursive processing modules let you build structured, conditional, and iterative processing flows. Use these when a sequence of operations must be repeated over many input datasets, applied conditionally on data properties, or executed in a distributed computing environment.

Data item management. Get item, Load item, Save item, Delete item, and Load raster allow you to retrieve, store, and remove data items (seismic gathers, velocity models, picking items, images, and other project objects) within a processing flow. These modules are the connectors between disk storage and in-memory processing steps.

Table and file operations. Create table, Import table, Export table, Enumerate files in folder, Generate filename, Parse filename, and Generate string handle ASCII and binary tables, file-system enumeration, and string formatting. These are essential for integrating external data (navigation files, statics tables, auxiliary picks) into a g-Platform workflow and for writing results back to disk in standard formats.

Trace and gather manipulation. Concatenate gathers, Create empty gather, Modify traces in gather, Reverse gather, Addition Traces, Seismic gather interpolation, Recalculate 3D offsets, Rebuild SP using FFID, Get Trace headers, and Populate trace headers from table cover the most common gather-level editing tasks — merging shot records, filling in missing traces, modifying or copying header word values, reordering traces, and computing geometry attributes.

Signal conditioning. Apply operator, Comparator, Convolutor, Resample, Fast median filtering, Phase Normalization, Wavelet conversion, and Signal Noise Attributes perform trace-level signal processing operations such as operator application, resampling to a new sample interval, median-based noise suppression, phase correction, wavelet shaping, and signal-to-noise estimation. These modules are typically used as lightweight conditioning steps within a larger processing sequence.

Vibroseis-specific utilities. Conversion for Vibroseis Data, Minimum Phase Conversion for Vibroseis Data, and Create deblending operators for vibroseis data address the special requirements of vibroseis acquisition: pilot sweep correlation, phase conversion, and the construction of operators needed to separate blended vibroseis shot records.

Picking and polygon tools. 4D picking and Polygon picking provide interactive and automated picking capabilities used to define time-lapse differences or to delineate regions of interest on seismic sections and maps.

Visualization and QC. Visualization 3D volume, MF Visualization 3D volume, Visualization 3D cube anisotropy, Crossplot by map, Read continuous time receiver gather, and Signal Noise Attributes provide display and quality-control tools for inspecting intermediate results during a processing sequence, checking data integrity, and evaluating anisotropy or amplitude attributes in three-dimensional volumes.

Scripting and automation. Python calculator, Verb execution, Apply Topography From ASCII, and Merge Geometry Points extend the platform with custom scripting, external verb invocation, and geometry integration from ASCII sources. These are useful when standard modules do not cover a project-specific operation and a custom calculation or external tool call is required.
