How do I search for a DNA sequence?
To show the Find controls, click Edit → Find.
The Find controls will appear near the bottom of the window.
Find DNA sequence: will be chosen by default.
To search for a specific DNA sequence, type the query in the search box, then click Next.
To allow multiple bases at a specific position in the query sequence, use parentheses to enclose the set of allowed bases.
In the example shown in the screenshot, either A or G will be allowed at the designated position. SnapGene will find matches to either GGTCTACTTC or GGTCTGCTTC.
Alternatively, to allow multiple bases at a position, use a degenerate DNA letter code such as R.
To view a list of DNA letter codes, click Tools → Letter Codes.
To exclude bases at a particular position, use an exclamation point in front of the forbidden bases. For example, !R means not A, G, or R.
Alternatively, enclose the excluded bases in parentheses. For example, !(AG) means not A, G, or R.
To search for a degenerate base, enclose the query in quotes. For example, a search for R will find all matches to A or G or R, but a search for "R" will find only bases that are actually represented as R.
To review or reuse recent searches, click the arrow button on the search box.
In Map view, a matching DNA sequence will be highlighted in blue.
In Sequence view, a matching DNA sequence on either strand will be highlighted in green.
