( #3333=superdoc: print w/replies, xml ) Need Help??

In general, messages like "Can't call method "location" on an undefined value ..." mean that you are trying to call a method on an object that doesn't exist (either you haven't created it with its constructor or the object has been destroyed). In this case, it appears that the code that is trying to call a method is in one of the Bio::SeqIO modules. That doesn't rule your code out entirely, but it does make it harder to track down the problem. You might check the docs for that series of modules to see if there are any hints there.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
