No spline term is found

[EmmanuelleKris]

Hello,
Again me... :)
So, I made my model:

fbutton = @formula(0 ~ 1 )
fstim= @formula(0 ~ 1 )
fsacc= @formula(0 ~ 1+spl(sac_amplitude,10))

bfsacc = firbasis((-0.1, 0.8), sfreq)
bfstim = firbasis((-0.2, 0.8), sfreq)
bfbutton= firbasis((-0.25, 0.254), sfreq)

bfDict = [ "stimonset" => (fstim, bfstim),
"buttonpress" => (fbutton, bfbutton),
"saccade" => (fsacc,bfsacc)]

m = Unfold.fit(UnfoldModel,bfDict,eegevent,Data,eventcolumn = "event")
I can plot results with plot_erp but I can't plot splines:

plot_splines(m)

AssertionError: No spline term is found in UnfoldModel. Does your UnfoldModel really have a spl(...) or other AbstractSplineTerm?
whereas I have 9 spline for sac_amplitude...

Thanks! I replicated the issue, this is a bug in UnfoldMakie. I'll create an issue right away.

The problem is that right now only the first event-type is checked for a spline-term. So if you urgently need this functionality, you would need to rename your events so that "saccade" is alphabetically the first one. e.g. you could use this code:

replace!(evts.event,"saccade"=>"a_saccade") # in place, 
...
bfDict = [...
 "saccade" => (fsacc,bfsacc)]

Hello
So I've tried different tricks "accade", "zsaccade" but it doesn't change the final order in results and so I get the same error.

but it works if I change the order in my design (saccade in the first)

bfDict = [ #]
"saccade" => (fsacc,bfsacc),
"stimonset" => (fstim, bfstim),
"buttonpress" => (fbutton, bfbutton)]

ah great! I had tested both but thought the re-ordering didnt work for me. Maybe some second dependency - but the bug is filled and we will fix it soon :)

Thank you!
