Hi All
I have a small issue in arranging data with a array ref .
$arrayref = [ [ [ 'user1, 'c'], [ 'user2', 'a'], [ 'user2', 'b' ],[
'user2', 'd' ],[ 'user3', 'a' ],[ 'user2', 'f' ] ] ];
i tried the following
my %sh ;
foreach my $i ( @$arrayref) {
push (@{$sh{$i->[0]}},{group => [$i->[1] } )
It might not look nice but I would do the following:
#!/usr/local/bin/perl
use strict;
use warnings;
my $arrayref = [ [ [ 'user1', 'c'], [ 'user2', 'a'], [ 'user2', 'b' ],[
'user2', 'd' ],[ 'user3', 'a' ],[ 'user2', 'f' ] ] ];
my %hash;
foreach my $arrayreference ( @{${$arrayref}[0]} ) {

HI,
I have a file with sequences each sequence is 200 pb long and I have 30K
lines
ATGGATAGATA\n
TTCGATTCATT\n
GCCTAGACAT\n
TTGCATAGACTA\n
I want to calculate the AT ratio of each base based on their position
(3/4) for the 1st position, 3/4 on the second, (0/4) on the 3rd...
I am beginner
"200 pb" -- does pb mean petabytes?
If so, those aren't going to fit in memory; you're going to have to read the
file line by line, accumulating totals and ratios as you go.

Hi Nathalie
I'm absolute newbie in terms of Perl but take into account the use of PDL
that will help you better manage vectors, matrix and number crunch
calculations.

Does your data look like this? With 10, 11, or 12 characters per line?
I'm afraid I don't know what a pb is, are yo

this comment is for both you and the OP. you should format complex data
so you can read it. it makes it much easier to edit an
