-*Flexible selection criteria.* The original Neurosynth has a fixed number of terms and meta-analyses. With*Neurosynth Compose* you can flexibly search the NeuroStore database using a powerful and flexible search to precisely define your search criteria.

-*Combine expert knowledge with automated selection.* Automated study selection is inherently an noisy and imperfect measure. With *Neurosynth Compose*, you can use automated study selection as a first pass, and later apply your own expert criteria to refine study inclusion criteria.
28

-*Correct data extraction errors.* Automated extraction can miss entire tables of coordinates (e.g. supplementary materials), duplicate coordinates, and groups distinct sets of Analyses (e.g. Contrasts) into a single group. Now, you can correct these data to make your meta-analysis more precise.
