Note: This module is deprecated. It is retained for compatibility with older processing workflows and should not be used in new projects.
Convert MF DB migrates an existing MultiFocusing (MF) database file (.kdb) from an older format to the current format, preserving all stored focusing parameters, time tables, aperture settings, and geometry. The conversion is performed directly between the source and destination database files — no seismic trace data is required as input.
Use this module when you have an MF analysis database created by an earlier version of g-Platform that cannot be read by the current MultiFocusing workflows. Select the storage type that matches the geometry of the original survey (2D or 3D, zero-offset or common-offset), then specify the source and destination database file paths. The module reads the full geometry, quantization table, and aperture from the source file and writes them into a newly formatted output file.
This module does not consume seismic trace data. All input is provided through the Parameters section as file paths to existing MF database files (.kdb).
Specifies the geometry and offset type of the MF database to be converted. Select the option that matches the type of the source database file:
2D — Zero-offset MultiFocusing results from a 2D survey. Geometry is stored as a list of bin points along a single line.
2D CO — Common-offset MultiFocusing results from a 2D survey. Geometry is stored as a list of bin points with associated per-offset trace vectors.
3D — Zero-offset MultiFocusing results from a 3D survey. Geometry is stored on a full bin grid (inline/crossline).
3D CO — Common-offset MultiFocusing results from a 3D survey. Geometry is stored on a bin grid with per-offset trace vectors.
Default: 2D. Choosing the wrong storage type for a given database will cause the module to fail with an invalid geometry error.
The full path to the existing MF database file (.kdb) that you want to convert. This is the source file — it must already exist and must have been created by a previous MultiFocusing analysis run. The file is opened in read-only mode; its contents are not modified during conversion.
Accepted file extension: .kdb
The full path for the output MF database file (.kdb) that will be created in the current format. The module writes all focusing parameters, the time quantization table, aperture value, and geometry from the source database into this new file. If a file already exists at this path it will be overwritten.
Accepted file extension: .kdb. It is recommended to use a different file name than the source to avoid accidental data loss.
Selects whether processing is performed on the CPU or a GPU accelerator. For this module, which performs file-format conversion with minimal computation, CPU execution is sufficient in all practical cases.
Controls whether the job is dispatched to remote cluster nodes. Because this module converts a single local database file, distributed execution is not typically needed.
Sets the number of records processed per internal batch. This setting affects memory usage during conversion but does not change the output.
When distributed execution is enabled, this option restricts the number of CPU threads used on each remote node, which can help manage system load in shared cluster environments.
An optional text label appended to the job name for identification in cluster job queues and processing logs.
Enables manual assignment of processing threads to specific CPU cores. Enable this option only when precise control over CPU resource allocation is required on the local machine.
Specifies the CPU core mask or list to use when custom affinity is enabled. Leave at default unless your system administrator has provided specific affinity settings for your workstation.
Sets the number of CPU threads to use during processing. For a database format conversion, a single thread is typically sufficient. Increasing this value will have little effect on performance for this module.
When enabled, this module is bypassed during flow execution without removing it from the processing sequence. Use this option to temporarily disable the conversion step while keeping the flow configuration intact for future use.
This module does not produce seismic trace output. The result is a converted MF database file (.kdb) written to the path specified in the Out Storage file parameter. This file can subsequently be used by current-version MultiFocusing analysis and imaging modules within g-Platform.
