primer3_core - Designs primers for PCR
primer3_core [-format_output] [-strict_tags] [< input_file]
primer3_core picks primers for PCR reactions, considering as criteria oligonucleotide melting temperature, size, GC content and
primer-dimer possibilities, PCR product size, positional constraints within the source sequence, and miscellaneous other constraints.
By default, primer3_core accepts input and produces output in Boulder-io format, a pre-XML text-based input/output format for
program-to-program data interchange format. The Boulder-io format and the commands that primer3_core understands are described in the
README file, which on Debian systems can be found in /usr/share/doc/primer3/.
Prints a more user-oriented report for each sequence.
primer3_core echoes and ignores any tags it does not recognize, unless the -strict_tags flag is set on the command line, in which case
primer3_core prints an error in the PRIMER_ERROR output tag, and prints additional information on stdout; this option can be useful for
debugging systems that incorporate primer.
The old flag -2x_compat is no longer supported.
EXIT STATUS CODES
o 0 on normal operation.
o -1 under the following conditions: illegal command-line arguments, unable to fflush stdout, unable to open (for writing and creating) a
.for, .rev or .int file (probably due to a protection problem).
o -2 on out-of-memory.
o -3 empty input.
o -4 error in a "Global" input tag (message in PRIMER_ERROR).
