Hello, One aspect of BioMart that our users find very confusing is when they have a result in the web UI and then they want to some column attributes to display for that result that suddenly it returns no result rows or far fewer than before. Then they have to figure out which of the attributes they added is causing this to happen. I think this is due to the fact that the disappearing rows had no value for that attribute dimension and it seems BioMart always does INNER JOIN from the main table across any dimension table instead of a LEFT JOIN which to me would make more sense? Is there a way to change this behavior or am I doing something wrong in my mart design?
best, Leandro
