This workflow snippet illustrates how to filter multiple columns using a flow variable. For this, we extract the column names of our data and create a collection column containing the desired column names. We then generate a variable that we use in the column filter node in the flow variables tab for "included_names". As example we use genes and their GO terms located on the X chromosome downloaded from Ensembl Biomart and remove the column "Gene Synonym" from the input data
