I have been trying to use the different options of the deseas function in
gretl. All the options I used seem to work as intended except the arima
option. To be more specific I have tried to build a deseasonalizing
procedure in which a certain arima model is imposed. According to the gretl
reference manual this should be done by building a bundle and using "arima"
and a 6x1 matrix which defines the model, like in the following example:
matrix start ={0,2,1,0,1,1}
bundle b=defbundle(verbose=2,seats=1,outliers=7, arima=start)
The bundle definition works, i.e a bundle b is built, but function deseas
fails because it does not recognize the arima key
I attach a file with data and a short script should something be unclear.
Please, let me know if I failed to follow the manual or there is something
strange going on with the program.
And since we are at the end of 2022, a happy new year!

Thank you for the report, Javier - and also for the wishes. One more
time today I'll say sorry for the delay, there apparently has been a
technical problem with the mailing lists.
I can easily replicate your problem, this bug must somehow have crept in
recently, because I'm fairly confident this thing worked when all these
options were first introduced (about a year ago?).
Internal comments: The error message must come from 'check_bundled_item
in lib/src/gretl_bundle.c, after in line 1860 the check 'if (targ ==
NULL) ' holds. And indeed in 'deseas_options_template' in
plugin/tramo-x12a.c in line 2232 we have 'gretl_bundle_set_matrix(b,
"arima", NULL);'. I guess either the check would have to be more
elaborate, or perhaps the initialization should be to an explicit empty
matrix or so, instead of a NULL value. (If there's a difference at the C
level, not sure.)

This problem should now be fixed in git and snapshots. I too would like to thank Javier
for a very clear error report.

Thanks, Allin. I also noticed in the code a FIXME concerning
translations (or their enablement) for deseas output or error messages.
I've opened an internal ticket for that.
cheers
