Hi...

Using x13 .. on Eviews 9.5.

Within the GUI it is indeed possible to use the dialogs to (say) perform: a) model selection via tramo, with b) a user regressor AND c) have *NO seasonal adjustment* performed...However, it is NOT possible to replicate the correct specs via command line.

Although not documented in your help files, it looks like the following should work...
But it actually does not work....*because the following is automatically (wrongly) appended to the x13 spec text file*
In other words, the entire spec generated by the code will render:

series{
2. title = "I001"
3. start = 2009.12
4. modelspan = (2009.12, 2016.09)
5. name = "I001"
6. file = "C:\Users\xxx\AppData\ev_temp\EVX13TMP.DAT"
7. decimals = 1
8. }
9. automdl{
10. maxdiff = (2 1)
11. maxorder = (2,1)
12. mixed = yes
13. fcstlim = 15
14. ljungboxlimit = 0.95
15. checkmu = yes
16. acceptdefault = no
17. }
18. regression{
19. user = (gp1)
20. file = "C:\Users\xxx\AppData\ev_temp\EVX13TMP.VAR"
21. format = "datevalue"
22. aictest = (user)
23. }
...
28. x11{
29. save = (d11)
30. }

And clearly, lines 28 onwards are wrong.

Could you please advise a workaround to perform the desired action (in a nutshell, no seasonal adjustment after tramo) ?

There is an undocumented option "noseas" that tells X-13 to not do seasonal adjustment.

Currently it doesn't quite work though since even with that option, EViews tries to read the D11 series back in. We'll get that issue fixed.

Thank you Gareth.
Looking forward to the fix..
In the meantime... is it possible to feed a correct x13 spec file into eviews, in any other way?

What are you trying to do? What's the end goal?

Thank you Gareth.
The goal is not seasonal adjustment. I could fetch the output series that I may be interested on (for example accessing certain types of outliers) directly from the text output of x13.. without having to have eviews trying to retrieve automatically a particular series (e.g, d11)....d11 is by construction not needed/generated in this context.

You're probably out of luck then.
