( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I refined my question a little more. I have a string of letters [ACGTacgtNn] from which I want to find a particular instance of a regexp, let's say:
/ACCAAC[ACGTacgtNn]{6}CTA[ACGTacgtNn]{1}ATG[ACGTacgtNn]{1,2}GATGTT/

I can do this just fine, but what if I want to match the above regexp with a tolerance of 2 minmatches for single characters. Below I have an example:
$buf =~ m/(A)(C)(C)(A)(A)(C)([ACGTacgtNn]{6})(CTA[ACGTacgtNn]{1})(A)(T +)(G)([ACGTacgtNn]{1,2})(G)(A)(T)(G)(T)(T)(?{ print $-[0]," ",scalar@-,"\n"; })(?!)/;
this will print the position of the match in $buf, followed by 19 (the number of submatches). I want to be able to return a match from 17-19 submathes, not just all 19. Thanks. Vince

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
