Task:  Detection Cloning Sequencing Primer_List Primer_Check

Select primer pairs to detect the given template sequence. Optionally targets and included/excluded regions can be specified. Mark an included region to pick primers fixed at its the boundaries. The quality of the primers might be low. Pick a series of primers on both strands for sequencing. Optionally the regions of interest can be marked using targets. Returns a list of all possible primers the can be designed on the template sequence. Optionally targets and included/exlcuded regions can be specified. Evaluate a primer of known sequence with the given settings.
