multiple key value hash problem

kumarboston

Hi All,

I have two tables of data, one contains 9 columns and another has 7 columns,
both the tables has 3 column common, now what i am trying to do is to merge the two tables in one using hash.
I used the first tables as the hash and made 4th column as the key and rest 5,6,7,8,9 as the values and now i read the another table and if the values existes then print the information from both the tables.
here is my code

Expand|Select|Wrap|Line Numbers

 
#!/usr/bin/perl

use strict;

use warnings;

my  (%hashname,$cnum,$ctotal,$count,$number,$pdb,$crossangle,$resname,$respos,$resdist,@temp);

open(SP,"<packing_cluster.dat") or die "Could not open $!";

while(<SP>)

{

    my $line1 = $_;chomp $line1;

    @temp = split (/\s/,$line1);

    $cnum       = $temp[1];

    $ctotal     = $temp[2];

    $count      = $temp[3];

    $number     = $temp[4];

    $pdb        = $temp[5];

    $crossangle = $temp[6];

    $resname    = $temp[7];

    $respos     = $temp[8];

    $resdist    = $temp[9];

    $hashname{$number} = ($pdb,$crossangle,$resname,$respos,$resdist);

}

close(SP);

my $cnt =0;

#while (($number,$pdb) = each (%hashname))

#{

#    print "$number => $pdb\n";

#    $cnt +=1;

#}

open(CG,"rmsd_cluster.dat") or die "Check relevant file";

while(<CG>)

{

        my $line2 = $_; chomp $line2;

        my @gsp   = split(/\s/,$line2);

        if (exists $hashname{$gsp[5]})

        {

            print "$gsp[2]\t$gsp[3]\t$gsp[4]\t$gsp[5]\t$hashname{$gsp[5]}\t$gsp[7]\t$crossangle\n";

            $cnt +=1;

        }

}

#close(WRITE1);

print "$cnt\n";

the problem is i am not able to print the table in desired way.
Any help will be appreciated.

Thanks

May we please see some sample data?

at a minimum this line looks wrong:

Expand|Select|Wrap|Line Numbers

$hashname{$number} = ($pdb,$crossangle,$resname,$respos,$resdist);

you want to use square brackets to assign an array to a hash key:

Expand|Select|Wrap|Line Numbers

$hashname{$number} = [$pdb,$crossangle,$resname,$respos,$resdist];

thats because its actually a reference to an array.

hi the sample data looks like

table 1

cnum ctotal count number pdb crossangle resname respos resdist
2 148 1 5265 xxx 25.3 ALA 25 6.6
2 148 2 4414 yyy 13.6 GLY 32 5.1

table 2
cnum ctotal count number pdb rmsd
2 148 1 5265 xxx 2.5
2 148 2 4414 yyy 1.3

now i am tying to merge the two table so that i can have one comple table rather than 2. I am trying to make number(table1) as key and rest column as values(table 1) and now matching the number (in table 2) and then merging the tables.

thanks
kumar
