Your first segment will get always undefs or whatever happens to be lying around in $1,$2,$3 because the 'do' in a 'do/while' loop is always executed once before the first time the while expression is tested for a match. You probably want to change this into a normal while loop like this:
my $ranking_dgp = 0; while ( $text =~ m{gene\=(ENSG\d+).*?<TD>\s+(\d+|X|Y)\s+</TD>.*? <TD>.*?<TD>.*?<TD>.*?<TD>\s(\d.\d+)\s\<\/TD\>}gsm){ my $gene = $1; my $chromosone = $2; my $score_dgp = $3; $ranking_dgp = $ranking_dgp + 1; push @gene_score, [ $gene, $chromosone, $score_dgp, $ranking_d +gp ]; } print Dumper @gene_score;
