deconseq syntax error

Question

[sara.zahran]

Hello, I am trying to removal human sequences from metagenome sequences using deconseq-standalone-0.4.3, first I downloaded hs_ref_GRCh37 conseq databases s1, s2 and s3 then I modified the deconseqconfig.pm as follows:

 use constant DBS => {hsref => {name => 'hs_ref_GRCh37_s1','hs_ref_GRCh37_s2','hs_ref_GRCh37_s3',
                       db => 'hs_ref_GRCh37_s1,hs_ref_GRCh37_s2,hs_ref_GRCh37_s3'},
                        bact => {name => 'Viral genomes',
                                db => 'bactDB'}};

but I got an error as follows:

syntax error at /home/deconseq-standalone-0.4.3/DeconSeqConfig.pm line 20 near "db"
BEGIN not safe after errors--compilation aborted at /home/deconseq-standalone-0.4.3/DeconSeqConfig.pm line 25
compilation failed in require at /home/deconseq-standalone-0.4.3/deconseq.pl line 26
BEGIN failed--compilation aborted at /home/deconseq-standalone-0.4.3/deconseq.pl line 26

I am not an expert in perl language and i am using virtualbox

how can i deal with these errors

thanks in advance
