VecScreen Match Categories

Vector contamination usually occurs at the beginning or end of a sequence; therefore, different criteria are applied for terminal and internal matches. VecScreen considers a match to be terminal if it starts within 25 bases of the beginning of the query sequence or stops within 25 bases of the end of the sequence. Matches are categorized according to the expected frequency of an alignment with the same score occurring between random sequences.

Strong Match to Vector
(Expect 1 random match in 1,000,000 queries of length 350 kb.)
Terminal match with Score ≥ 24.
Internal match with Score ≥ 30.
 
Moderate Match to Vector
(Expect 1 random match in 1,000 queries of length 350 kb.)
Terminal match with Score 19 to 23.
Internal match with Score 25 to 29.
 
Weak Match to Vector
(Expect 1 random match in 40 queries of length 350 kb.)
Terminal match with Score 16 to 18.
Internal match with Score 23 to 24.
 
Segment of Suspect Origin
Any segment of fewer than 50 bases between two vector matches or between a match and an end.
