mohamedgadallah commented 2 years ago

I am trying to use the volcano plot (visuz.GeneExpression.volcano) put I always get this error.

AssertionError: dataframe contains non-numeric values in pv column.

However, all data in pv column is numeric

@mohamedgadallah

Check if your p value column is numeric or not. Sometimes formatting issue creates a problem.
