Concatenate Gathers module is used to merge two or more seismic gathers sequentially into a single output gather. It is typically applied when combining datasets from different processing stages, split acquisitions, or segmented records.
This module ensures continuity of traces while maintaining consistent sampling and indexing.
Gathers - this section deals with input gathers. There can be many input gathers. To add multiple input gathers to concatenate, the user should click on 
icon.
Input gather A - this is the 1st input gather. Connect/reference to the output gather of the corresponding module.
Auto resample according to first gather in list - this option automatically resamples in the other input gathers based on the first gather (Input gather A). By default, FALSE (Unchecked).
Rebuild record indexes - By default, TRUE (Checked). Recalculates trace and record indices after concatenation to ensure continuous and unique indexing.
Number of threads - One less than total no of nodes/threads to execute a job in multi-thread mode. Limit number of threads on main machine.
Skip - By default, FALSE(Unchecked). This option helps to bypass the module from the workflow.
Output gather - outputs the concatenated/combined gather.
There is no information available for this module.
In this example workflow, we are concatenating/adding multiple gathers to make it a single output gather.
Likewise, the user can add as many input gathers as they want. After making the necessary connections/references, execute the module. It will not produce any Vista items as a visualization QC items however it produces an output gather which can be used for further processing.
There are no action items available for this module.
