I think you are running the script properly. I ran the same command right now and got the expected result :
ukko(12): perl query-umls-similarity-webinterface.pl --url http://maraca.d.umn.edu hand skull Default Settings: --measure path --sab MSH --rel PAR/CHD User Settings: --set http://maraca.d.umn.edu 0.1111<>hand(C0018563)<>skull(C0037303) There was a brief restart of maraca yesterday, so I suppose it's possible you submitted this during that. Could you try again and see what happens? Also, you can also send these queries to http://atlas.ahc.umn.edu ukko(31): perl query-umls-similarity-webinterface.pl --url http://atlas.ahc.umn.edu hand skull Default Settings: --measure path --sab MSH --rel PAR/CHD User Settings: --set http://atlas.ahc.umn.edu 0.1111<>hand(C0018563)<>skull(C0037303) Good luck, Ted On Tue, Jan 26, 2016 at 1:46 AM, suranja...@gmail.com [umls-similarity] < umls-similarity@yahoogroups.com> wrote: > > > Hello, > > I want to use the perl script "query-umls-similarity-webinterface.pl" to > find the CUI/term similarity between two given inputs.
