PCD also has a more powerful search interface called MegaSearch. MegaSearch allows for additional customization of downloaded results and also allows users to preview the results before downloading. Access the MegaSearch interface via the link in the Search menu. To begin a search, first select the Data Type (Fig. 20A).

Once a Data Type is selected, the Query section appears (Fig. 20B) where further filters can be selected. Note the number of data rows that appears right above the Query box. This number can be refreshed to reflect the number of data rows yielded by the search parameters by clicking the "Refresh Count" button (Fig. 20B). This helps the user determine how much data is being returned by the search. Once the search parameters are set, there are options for which data fields are downloaded (Fig. 20C). Users can also view the data prior to download or download a FASTA file (dependent on Data Type).
