It's still not working. A wierd thing, i'm positive that i've changed the query-umls-similarity-webinterface.pl as you said: my $qurl = "$url/cgi-bin/umls_similarity/umls_similarity.cgi?word1=$i1&word2=$i2&sab=$sab&rel=$rel&similarity=$smeasure&button=$button&sabdef=$sabdef&reldef=$reldef&relatedness=$rmeasure";
But I still get the same output: (base) jon@jon:~/UMLS/UMLS-Similarity-1.47/utils$ query-umls-similarity-webinterface.pl hand skull --url http://maraca.d.umn.edu Default Settings: --measure path --sab MSH --rel PAR/CHD User Settings: --set http://maraca.d.umn.edu 500 Can't connect to maraca.d.umn.edu:80http://maraca.d.umn.edu/cgi-bin/umls_similarity.cgi?word1=hand&word2=skull&sab=MSH&rel=PAR%2FCHD&similarity=path&button=Compute+Similarity&sabdef=UMLS_ALL&reldef=CUI%2FPAR%2FCHD%2FRB%2FRN&relatedness=vector <>()<>()
