# Selecting an Assembly

Choosing an *Assembly* from the drop-down list at the top will display the associated library files in the panel below. Assemblies are named by the species and the build version (e.g. Homo sapiens (human) - hg19). Different build versions for the same species are regarded as separate assemblies (Figure 1). Administrative users can delete a selected assembly by clicking the **bin** (![delete\_icon\_x\_cross\_red](/files/tLCxeIetbhSrADOYXxwq)) icon.
