Description
Cyclic loop
This module behaves as a cycle in a flow, it can contain several sub modules. The input data is processed in according to the data sort order. Loop can also be used to select specific gathers, since it has parameters (step and interval) for choosing the gathers you want to process. This module is best used for small amounts of data (for example 2D data), while for a large data volume, the “Seismic distributed loop” module should be used as it uses parallel calculation to distribute the data over several clusters.
Input data
Loop item
Parameters
Sequential gather number
Number of the current iteration (sequential gather)
It is an incrementing number that indicates the current sequential gather being passed through the workflow
[Iteration Number] will be automatically incremented by the <Loop> module after the current gather has completed the workflow, when the [Auto Increment] parameter is selected
First seq. gather
Sequential number of the first gather according to the input data sort order
The number of the first iteration should be within the range of [LoopItem] input parameter
Used by 'ExecuteAll' mode of <Loop> procedure
Last seq. gather
Sequential number of the last gather according to the input data sort order
The number of the last iteration should be within the range of [LoopItem] input parameter
Used by 'ExecuteAll' mode of <Loop> procedure
Seq. gather increment
Iteration increment
Indicates number of iterations (sequential gathers) that will be skipped each time a <Loop> completes execution
Active when [Auto Increment] = is selected
Auto increment
If unchecked the iteration mode is to increment only in manual mode. Manual mode is when you double click on the module «Loop» in the workflow. In this case the number of gathers will not increase and we will retain the current value. When we use the execute all modules mode, the data will increment and the gathers will change automatically
Stop in error case
If checked, execution will stop if an error occurs. If not checked, the cycle will run without stopping and skipping problem module
Movie time delay
Time delay between iteration executions. It can used to automatically review data views while the loops execute in movie mode
