Error for most trinotateR functions: Error in eval(bysub, x, parent.frame()) : object 'go' not found

Hello,
I just generated a Trinotate annotation report, and I'm trying to summarize the findings of the report with trinotateR. I can run all of the functions outlined in README.md, but when I try to summarize other aspects of the report using summary_GO, summary blast, summary_pfam, etc, I encounter this error:

summary_GO(x)
Error in eval(bysub, x, parent.frame()) : object 'go' not found

For each of the summary functions, do I need to go through the same steps as outlined in the README.md file for the pfam summary table?

Yes, you need to split the annotations into separate rows and columns first and then summarize. This should work for GO columns and the default is gene_ontology_blast.

go <- split_go(x)
summary_GO(go)
