[DEFECT] SyntheticHistory ROM Interpolation Broken

[dylanjm]

Thank you for the defect report

• I am using the latest version of RAVEN.
• I have read the Wiki.
• I have created a minimum, reproducible example
  that demonstrates the defect.

Defect Description

I am trying to train a SyntheticHistory ROM using a 6 sets of data. I want the data sets 0-4 to represent years 2024-2028 and then I want to interpolate between 2029-2054 using the 5 set of data.

When performing the training in RAVEN I get the following error:

Traceback (most recent call last):

Steps to Reproduce

See attached files

Expected Behavior

I expect the interpolation to happen without issue.

For Change Control Board: Issue Review

• Is it tagged with a type: defect or task?
• Is it tagged with a priority: critical, normal or minor?
• If it will impact requirements or requirements tests, is it tagged with requirements?
• If it is a defect, can it cause wrong results for users? If so an email needs to be sent to the users.
• Is a rationale provided? (Such as explaining why the improvement is needed or why current code is wrong.)

For Change Control Board: Issue Closure

• If the issue is a defect, is the defect fixed?
• If the issue is a defect, is the defect tested for in the regression test system? (If not explain why not.)
• If the issue can impact users, has an email to the users group been written (the email should specify if the defect impacts stable or master)?
• If the issue is a defect, does it impact the latest release branch? If yes, is there any issue tagged with release (create if needed)?
• If the issue is being closed without a pull request, has an explanation of why it is being closed been provided?

The issue appears to be in SyntheticHistory.py. When trying to set global ROM features, the loop
for algo in self._tsaAlgorithms: ... (line 365)
should probably be looping over self._tsaGlobalAlgorithms instead.

[GabrielSoto-INL]

Working on fixing what Jacob just described. But I think the actual issue happens when there are multiple algorithm nodes with different targets (e.g., two <fourier> nodes, one for target_0 and one for target_1). Seems I had implemented a fix but it's commented out on Line 368... unsure why that is, I will re-implemented in another branch with testing to cover that error.
