No to what?


I am still pretty confused, but is this what you are trying to do?

Code:
#!usr/bin/perl
use strict;
use warnings;

my @set = (15, 150, 200, 250);
my @vals = (208, 258, 56, 123);

my @vals_sorted = sort {$a <=> $b} @vals;
foreach my $n (@set) {
   print "Closest to $n = ", shift @vals_sorted, "\n";
}

I don't understand what you mean. Are you prohibited from using sort?

Also the columns already appear to be sorted so the next line is the closest one, no?

hi kevin
the logic is perfect
but instead of writing the values in arrays i would like to assign the no.of values from column1 and column2 i.e defing @set as values from column 1 and @val as column 2.
input file;;
chr1 100 112
chr1 150 300
chr1 80 400
.............286
.............100

script needs correction

#!usr/bin/perl -w
use strict;
use warnings;
my $infile1 = 're5.txt';
open IN10, "< $infile1" or die "Can't open $infile1 : $!";
my %values;
while (<F1>) {
chomp;
my ($chrom,$value1,$value2) = split /\t/;
my $rec = {value1 => $value1, value2 => $value2
};
push @{$vlaues{$chrom}}, $rec;
}
my @set = $value1;
my @vals = $value2;
my @vals_sorted = sort {$a <=> $b} @vals;
foreach my $n (@set) {
print "Closest to $n = ", shift @vals_sorted, "\n";
}

Thanx for the ideas
Funny laughs @other mails

sorry for posting early

I caught with some group meeting crap.
well here I'm trying to recall the column1 ($start) from file1, IN10 and column2, ($middle) from file2, IN11. I think I screwed up some where.Smilie

note :I'm giving sample outputs of script so far except calculation of the closest point
