.SH "NAME"
primer3_core \- Designs primers for PCR
.SH "SYNOPSIS"
.HP 13
\fBprimer3_core\fR [\-format_output] [\-strict_tags] [<\ \fIinput_file\fR]
.SH "DESCRIPTION"
.PP
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\&.
.PP
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
\fIREADME\fR
file, which on Debian systems can be found in
\fI/usr/share/doc/primer3/\fR\&.
.SH "OPTIONS"
.PP
\fB\-format_output\fR
.RS 4
Prints a more user\-oriented report for each sequence\&.
.RE
.PP
\fB\-strict_tags\fR
.RS 4
primer3_core echoes and ignores any tags it does not recognize, unless the
\fB\-strict_tags\fR
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\&.

.RS 4
\h'-04'\(bu\h'+03'\-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)\&.
