One way:
open(FOO,"filename") || die "Couldn't open filename: !$\n";
while(<FOO>) {
chomp();
($t1,$t2,$t3,$t4,$t5,$t6,$t7,$t8,$t9,$t10,$t11) = split;
$interestingdata = join("|",$t4,$t5,$t6,$t7,$t8);
$atomhash{$t2} = $interestingdata;
}
It would be more enlightening to name the variables so you
know what they are. To extract, you have to either walk through
the entire hash or selectively extract the ones you want.
Selective:
$wanttosee = $atomhash{$somenumber};
Everything:
while (($atom,$values) = each(%atomhash)) {
($t4,$t5,$t6,$t7,$t8) = split(/|\/,$values);
# do something useful here. The print is a sample
print "Atom number is $atom. Data are:\n"
print "\t$t4\t$t5\t$t6\t$t7\t$t8\n";
}
