[Bioperl-l] Bio::DB::EUtilities esearch PhraseNotFound error

[Scott Cain]

Hi Gabriel,

It looks to me like you've got a few things going wrong.  First, you
are using single quotes for the right hand side of the -term value.
In perl, single quotes are non-interpolating, which means variables
won't be substituted in.  However, if you switch to double quotes,
you'll still have a problem, because this:

  $genename[SYMB]

looks like you are trying to access an element of an array called
genename with a constant called SYMB, which of course you aren't, so
the perl interpreter will die with that.  You can rewrite that section
like this:

  $genename . '[SYMB] AND homo_sapiens[ORGN]'

so that the variable interpolation is moved out of the single quotes.

Scott
