In this group you can specify where to search for a pattern: in what region and in which strand (for nucleotide sequences). Also for nucleotide sequences it is possible to search for a pattern on the sequence translations.
Strand — for nucleotide sequences only. Specifies on which strand to search for a pattern: Direct, Reverse-complementary or Both strands.
Search in — for nucleotide sequences you can select the Translation value for this option. In this case the input pattern will be searched in the amino acid translations.
Region — specifies the sequence range where to search for a pattern. You can search in the whole sequence, specify a custom region or search in the selected region.
