The Convert TIF files module converts seismic field acquisition data stored in TIF (Tape-In-File) or TIF8 format into a standard seismic output format, typically SEG-D. TIF and TIF8 are container formats used by Sercel recording systems to store seismic records on disk with internal header bookkeeping. This module strips those container headers and writes only the raw seismic record data to the output files, one output file per input file.
Use this module when seismic field data has been delivered in TIF or TIF8 format and must be converted before it can be read by standard seismic processing workflows. Both the standard TIF format (using 32-bit record pointers) and the extended TIF8 format (using 64-bit record pointers, required for very large files exceeding 4 GB) are detected and handled automatically. Multiple files can be processed in a single run. The output files are named after the corresponding input files, placed in the specified output directory, and given the specified output extension.
Specifies the list of TIF or TIF8 seismic field data files to convert. Add one or more files using the file browser. Accepted extensions are .tif and .tif8. The module processes each file independently and produces one output file per input file. If a listed file does not exist on disk at the time of execution, that file is skipped and reported as a conversion error. Files in both standard TIF (32-bit pointer) and TIF8 (64-bit pointer) format are detected automatically — no separate setting is required.
Specifies the directory where the converted output files will be written. Each output file is named after the corresponding input file (same base name, without the original extension) and placed in this directory. Use the folder browser to select or create the target directory. Ensure that sufficient disk space is available, as the output files contain the full seismic record payload from each input TIF file.
Sets the file extension that will be appended to each output file name. The default value is .segd, which is the standard SEG-D format extension for seismic field data. Enter a different extension if the downstream processing workflow expects a different file suffix. The leading dot is optional — if omitted, it is added automatically. For example, entering segd and .segd are treated identically.
Selects whether the module runs on the CPU or GPU. File format conversion is an I/O-bound operation and runs on the CPU.
Controls whether the module is executed on a distributed processing cluster. When enabled, individual files may be distributed across multiple nodes for parallel conversion.
Sets the minimum number of files assigned to each processing node when distributed execution is enabled. Increasing this value reduces scheduling overhead but may result in less even load distribution across nodes.
When enabled in distributed execution mode, restricts the number of threads each remote node may use. This can be useful on shared cluster nodes where CPU resources need to be reserved for other jobs running concurrently.
An optional text suffix appended to the distributed job name. Use this to distinguish parallel jobs when multiple instances of this module are submitted to the cluster simultaneously.
When enabled, allows you to manually specify which CPU cores the module is allowed to use on the local machine. Leave disabled to let the operating system manage core assignment automatically.
Specifies the CPU core affinity mask when Set custom affinity is enabled. Restrict processing to specific cores if needed for system resource management.
Sets the maximum number of CPU threads used for processing. For file conversion, which is primarily limited by disk I/O rather than CPU computation, increasing the thread count beyond the number of input files provides no additional benefit.
When enabled, this module is skipped during processing flow execution without removing it from the processing sequence. Use this option to temporarily bypass the conversion step while testing or rerunning a workflow.
The module produces one converted output file for each successfully processed input TIF or TIF8 file. Output files are written to the specified output directory and named after the corresponding input file with the specified output extension (default: .segd). The output files contain the raw seismic record data extracted from the TIF container, without the TIF or TIF8 wrapper headers. If any input files cannot be opened or converted, an error is reported listing up to five of the failed file paths; successfully converted files are still written.
