Precision is undefined in this case, and NA will be returned.

[Aljovic]

Hello,

I try to run Augur on my Seurat data:

augur = calculate_auc(merged.cx3cr1_soupx, cell_type_col = "Cluster_Name", label_col = "Type")

However, I get the following error.
Caused by warning:
! While computing binary precision(), no predicted events were detected (i.e. true_positive + false_positive = 0).
Precision is undefined in this case, and NA will be returned.
Note that 6 true event(s) actually occured for the problematic event level, 'Ctrl'.Warning: There was 1 warning in mutate().
ℹ In argument: metrics = pred %>% map(metric_fun).

I have in total around 35K cells, 12 clusters, and each cluster has more than 20 cells. I'm probably missing something simple here. Would really appreciate your help.

All best!

Hi @Aljovic - not sure what could be going wrong here off the top of my head. Can you provide a reproducible example or else send me a subset of your data that produces this error? Can you also provide the output of sessionInfo()?
