I am trying to use Entrez'z Eutilitiy for a text mining module. I tried using the sample snippets from the pubmed website.
use LWP::Simple; # Download PubMed records that are indexed in MeSH for both asthma and # leukotrienes and were also published in 2009. $db = 'pubmed'; $query = 'asthma[mesh]+AND+leukotrienes[mesh]+AND+2009[pdat]'; #assemble the esearch URL $base = 'http://eutils.ncbi.nlm.nih.gov/entrez/eutils/'; $url = $base . "esearch.fcgi?db=$db&term=$query&usehistory=y"; #post the esearch URL $output = get($url);
I got get() function Fatal Error. I have the perl LWD module installed But I am still unable to solve this error. Can someone suggest me any error checking pointers?
