change expression during brain development 1. derfinder permits discovery of novel expressed & differen#ally bound regions 2. we iden#fied & validated gene expression changes in the developing brain 3. we have developed tools for reproducible shareable repor#ng 4. these tools can be easily be used to process 2,040 projects via recount
