Accumulation of Traces
This module gets traces and accumulates it in to a single gather. For example we try to compute stack in loop and necessary to view resultant stack on a screen.View after module “Stack” will produce only one trace, but we need a full stack.In this case we can use module “Set gather” to accumulate our stack for visualization.
Input DataItem
Input gather - connect/reference to the Output gather.
There are no parameters required for this module. It accumulates individual traces into a combined gather which eventually makes a stack section.
Auto-connection - By default, TRUE(Checked).It will automatically connects to the next module. To avoid auto-connect, the user should uncheck this option.
Bad data values option { Fix, Notify, Continue } - This is applicable whenever there is a bad value or NaN (Not a Number) in the data. By default, Notify. While testing, it is good to opt as Notify option. Once we understand the root cause of it,
the user can either choose the option Fix or Continue. In this way, the job won't stop/fail during the production.
Notify - It will notify the issue if there are any bad values or NaN. This will halt the workflow execution.
Fix - It will fix the bad values and continue executing the workflow.
Continue - This option will continue the execution of the workflow however if there are any bad values or NaN, it won't fix it.
Skip - By default, FALSE(Unchecked). This option helps to bypass the module from the workflow.
Output DataItem
Output gather - generates single trace as an output.
Merged gather - all the individual traces are accumulated and later combined to create a merged gather.
There is no information available for this module
In this example, we are creating a merged/stack section by using Set gather. As we mentioned earlier, all individual traces are concatenated/accumulated/combined together to create a merged/stack section.
It generates three vista items i.e., input gather, output gather and merged gather.
There are no action items available for this module
