Hi, I would like to annotate my data sets and enable users to search on these annotations. For example, suppose I have datasets from different microbial species and strains, grown on different media under different conditions. I can attach templates to all of my data that would have fields for species, strain, growth medium and treatment. Suppose now I want to look at all of the data from S.cerevisae, strain ABC, grown on a medium XYZ, under heat stress. How do I do that? I have looked around my Galaxy instance and on the Wiki, but I could not figure out how to search on template fields. Thanks. Yury -- Yury V.
