Hello PerlMonks!
I have a wierd problem. I am able to read the file, process it, and print to a file only
when I include the data in the script using __DATA__. When I read into the IN
filehandle and write to an out file I get a blank file. Any Ideas?
The following is the code:
#!/usr/bin/perl -w
use strict;
use Data::Dumper;
#open file for reading
open(IN,"/Users/me/Desktop/CCDS.current.txt") or die " Can't open file
+: $!";
#open out file for writing
open(OUT, ">/Users/me/Desktop/withdrawndata.txt");
#remove the header
my $firstline= <IN>;
chomp $firstline;
while(<IN>){
chomp; # remove the newline character
my @fields = split/\t/; # split the file into columns where eachli
+ne in it
#populates and array for that column.
if($fields[5] =~ m/Withdrawn/){ # print eachline that has "Withdra
+wn" in field[5]
print OUT "$_\n"; # print to file
}
}
close(IN);
close(OUT);
__DATA__
#chromosome nc_accession gene gene_id ccds_id ccds_stat
+us cds_strand cds_from cds_to
