## General


  


## Statistics

If a BLAST result is successfully mapped to one or several GO terms, these will be shown in the GOs column of the Main Sequence Table and this sequence row will turn **light-green**. Assigned GOs can be reviewed in the BLAST results Table (see [Show BLAST Results](https://biobam.atlassian.net/wiki/spaces/DOC/pages/694877/blast+-+Basic+Local+Sequence+Alignments#ShowBLASTResults) section and Figure 8 of that section).

Three different charts are available to summarise the mapping step:

- GO Mapping Distribution: Shows the distribution of the amount of Gene Ontology candidate terms assigned to each sequence during the GO Mapping step.
- EC Distribution for Blast Hits (Figure 5): Evidence Codes associated to the obtained GO pool
- EC Distribution for Sequences (Figure 6): This chart shows the distribution of GO evidence codes for the functional terms obtained during the mapping step. It gives an idea about how many annotations derive from automatic/computational annotations or manually curated ones.
- DB Resources of Mapping (Figure 7): This chart gives the distribution of the number of annotations (GO-terms) retrieved from the different source databases e.g. UniProt, PDB, TAIR etc.

> ⚠️ Commonly IEA (electronic annotation) is overwhelmed in the mapping results. However, the contribution of this (and other) type of annotation to the finally assigned annotation to the query set can be modulated at the annotation step.

## Export Mapping Results

A tab separator text file can be exported with the corresponding mapping results (**File > Export > Export Mapping Results**).
