Help: filtering, analyzing and downloading annotation

1 Filtering Annotations

The filters beneath each of the column headings in annotation table can be clicked to specify filtering parameters, or to map annotations to sequence identifier types other than UniProtKB accessions. More advanced queries can be entered into the 'Advanced' text box.

2 Viewing Annotation Statistics

Statistics on the selected annotation set are available in the numbers adjacent to the 'Statistics' header.

3 Viewing Annotations

The annotation table defaults to displaying an initial 25 annotations, however this can be increased by changing the value adjacent to the 'Sample size' header. Alternatively, clicking the arrow at the bottom of the annotation table will advance the display to the next 25 annotations. Many of the values in the annotation table can be clicked on, and will provide further information and navigation options (this includes GO terms and sequence identifiers).

4 Downloading Annotations

An entire set of annotations can be downloaded in a text file from QuickGO by selecting 'Association format'. Users can select the file compression option (gzip) and the number of annotations to include.

Use this filter to change between different sequence identifier types. QuickGO's default is to show annotations to UniProtKB (Swiss-Prot and TrEMBL) accession numbers.

QuickGO maps between different identifier types by using a combination of mapping files provided by the databases, and using identifier cross-references supplied by UniProtKB.

If more than one identifier type needs to be used to map all required sequences, drag the selected databases to change the order in which identifiers are found.

Filter annotations by protein IDs from any database:

QuickGO will map identifiers to UniProtKB Ac.s unless you have specified an alternative identifier type via the 'DB' filter box.

Filter by taxonomy

To filter by species/taxonomic group, list taxon identifiers in the text box or select one of the pre-defined taxonomic groups below.

	9606	Human
	10090	Mouse
	40674	Mammalia
	3398	Magnoliophyta (flowering plants)
	2759	Eukaryota
