+# A description of the BLAST results table
+The results page will show summary results for each sequence submitted with a graphical display of hits on the query sequence. A table of results for each combination of sequences and target database can be found by clicking on the drop down icon next to the species and genome assembly name. The results table lists the sequence similarity hits in order of E-value, but can be customised to reorder the table based on the different columns by clicking on the arrow next to each column heading. You can customise all rows, or select specific hits, by clicking on the box in the first column of each row.
+
+## E-value
+This is the number of times a match is expected to occur by chance. A lower E-value indicates greater similarity between sequences. 
+
+## Length
+Length
+Length of alignment between query and target sequence.
+
+## Alignment view
+Click on this to view the one-to-one alignment between the region of your query sequence and the subject sequence from the database. This alignment will show the length of coverage of your alignment and the presence of any gaps and mismatched regions.
+
+## % ID
+This score indicates the extent to which the query sequence and the hit have the same residue at the same position in an alignment.
+
+## Score
+The score gives an indication of how good the alignment is, with a higher score indicating a more exact alignment.
+
+## Genomic location
+Shows the genomic location of the hit in the selected species. You can click on the coordinates to view this location in the Ensembl Genome Browser.
+
+## Hit orientation
+The orientation of the hit sequence against the query sequence.
+
+## Hit start
+The position within the target sequence at which the hit started.
+
+## Hit end
+The position within the target sequence at which the hit ends.
+
+## Query start
+The first position within the query sequence that matches the beginning of the hit that BLAST returns
+
+## Query end
+Query end
+The last position within the query sequence that matches the beginning of the hit that BLAST returns
