Error while plotting stats

[suheyla2]

Hi Tashrif,

I received the following error below at the final step of debugging: plotting stats (harm_plot.py).
cvs files were generated successfully.

I think the error might be because my two sites do not have the same number of subjects, but the function assumes that they should have? FYI: In template creation, we expect two sites to not have a significantly different number of subjects to avoid bias but it is not necessary to have the exact same number of subjects in each site.

Thanks,
Suheyla

Hi Suheyla,

FYI: In template creation, we expect two sites to not have a significantly different number of subjects to avoid bias but it is not necessary to have the exact same number of subjects in each site.

News for me but hasn't it always been that we shall need a set of matching reference and target subjects for template creation? For a match to happen, it will always be the same number across two sites.

Matching is performed at the group level, not one to one. Suheyla
