I created a basic real time sequence that checks the time it takes for a signal to reach a certain threshold. On the LV side, I use the API to call this sequence. I make sure all channels and parameters are defined just like in the examples. However I keep getting Error -307650 that says " NI VeriStand: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". Any suggestion to help here? Thx. Code is attached.

There are two issues here: 1. The Stimulus Profile Editor is not indicating that there is an error with this sequence, although there is one. Note that the variable InitialTime is used in an expression, but is not declared as a parameter or local variable. 2. You do get an error at run-time because of this, but it is not terribly helpful (index out of range). You can fix this by adding an InitialTime local variable to your sequence. I filed CAR 338386 regarding this bug. After you do that, there is one additional thing you'll need to fix in your VI that runs the sequence to get it to get the results from the sequence correctly. You are not correctly using the Sequence Name value to read the Return Variable of the sequence. You are using the Session Name you used when deploying the sequence. That does not correspond to the sequence name. To get the sequence name, use the VI Get All Sequence Names on your stimulus profile session to get the array of names for all top-level sequences in that session, and then index out the first item, since you're only running one sequence. Example attached below:
