Hi,
I have a set of genetics data with more that 30,000 attributes. All of these attributes are in the categorical(nominal) data type, but I want to change all of them except for one to numerical data type . I couldn't do it by adding the operator "Nominal to Numerical" in the data flow because apparently RapidMiner Studio only supports up to 16384 attributes.
So I'm trying to change the data types from Turbo Prep, but I don't want to manually change the type for each attribute one by one. I'm wondering if there's a way to select all/multiple attributes in Turbo Prep and change everything at once?
Or if there are any other ways?
I attached a screenshot of a sample of my data. Hopefully that helps!

Thanks!
