Cant get any scripts to run

gkuffel22 has asked for the wisdom of the Perl Monks concerning the following question:

I am a new user of Perl and fairly new to programming in general. I am trying to analyze metagenomic DNA sequence data using the gene ontology database (GO). I am trying to automate this process using go-perl. I currently am using strawberry Perl on my 64 bit Windows machine. I have installed go-perl but when I try to run a script I get the following error code in my command line: no filehandle at C:/Perl64/site/lib/Data/Stag/BaseGenerator.pm line 473

Line 474 of Data::Stag::BaseGenerator (version Data-Stag-0.11) is a call to `confess` (Carp): `if (!$fh) { confess("no filehandle"); }` [download] which means it should also show you a full stack trace of the function calls. Please post the full stack trace using code tags. Perhaps you called a function with inappropriate arguments. Make sure you also use strict and warnings.	[reply] [d/l] [select]

GO::Basicparse_obo(undef)called at C:\Users\Gina\Downloads\cry.pl line 3 It seems your problem originates on line 3 of the cry.pl file. If you still need help, you'll need to post at least the 1st 3 lines of that file. See also: Basic debugging checklist	[reply]
