detect outlier in tramo/seats seasoanl adjustment

[punjaphp]

Hello,

I tried to detect outliers of my gdp series using the command below. It detected the period of (4 1999) which is a different outlier period detected from the default mode (4 2011). What is the program command for the default mode of TRAMO/SEATS?

show b_gdpr.tramoseats(save="sa sf", opt="iatip=1 aio=2 seat=2") b_gdpr

Thank you in advance

I've already got the same outlier. just left it blank, right?
show b_gdpr.tramoseats(save="sf sa") b_gdpr_ts

How come adding the option "iatip=1" gave a different outlier since it enabled auto detection?

Thank you
