Cross_match is not included as part of the Staden Package. It is available from Phil Green. http://www.genome.washington.edu/UWGC/analysistools/swat.htm
cross_matchprogram to search for sequencing vector. (Future versions may also check for other cloning vectors.) This allows for searching of multiple vector files. However as cross_match does not make use of primer and cut site information the vector detection is inherently less sensitive than
vector_clip(see section Screening against Vector Sequences).
