Hi,

While we're on the subject... how do people (and how does BASE) handle
multiple experimental factors.

Say a two-colour experiment was testing the following "conditions"

  mutantX vs. wild type in males
  mutantY vs. wild type in males
  mutantX vs. wild type in females
  mutantY vs. wild type in females

There are are two experimental factors here, "GeneticModification" and "Sex".
I guess the correct way to handle the downstream analysis (e.g. averaging and
colouring in ExperimentExplorer) is to treat this as a compound annotation
e.g. GeneticModification:Sex.  I don't think BASE would handle this at the
moment (you can only select one annotation at a time in the "Annotation
summary" menu), although it might be possible to produce the desired outcome
by crudely creating a "GeneticModification:Sex" AnnotationType.

Would you ever have two or more experimental factors that should not be
treated in this manner?  I can't think of a scenario off the top of my head.

cheers,
Bob.
