Figure 4.
Examples of boulder IO (A) input to primer3_core and (B) output from primer3_core. Panel A shows two primer design tasks (SEQUENCE_ID’s example 1 and example 2) separated by a line consisting only of an = character. PRIMER_NUM_RETURN is 1 for both tasks, because the values of tags beginning with PRIMER_… persist between design tasks. However, the value of tags beginning with SEQUENCE_…, such as SEQUENCE_EXCLUDED_REGION = 37,21 in example 1, affect only the current design task. Panel B shows abbreviated output corresponding to panel A.
