However, this isn't possible right now unless each dataset has the same number of columns. This is because column selection is mandatory for all training/test datasets. In order of preference, I suggest (1) moving to an approach where columns are not selected at all or (2) column selection is optional. Given that Galaxy can cut columns, I lean towards (1). This is a substantial change—what do others think? @bgruening @qiagu "}}
