NAME

MultiSkan - The great new MultiSkan!

VERSION

Version 0.02

SYNOPSIS

Used Multiskan Microplate Photometer (Thermo Scientific) for your experiment?

Just got a text file as your output?

Thinking it would be good if it had an app to give you an overview of all wells, and to help to group the data and do some simple stats for you?

GOOD! That means I'm not alone. This module does some simple tasks for you...

    use MultiSkan;
    
    my @groups = (
        'amp', 'A2B2C2',
        'tet', 'A4B4C4',
        'Blank', 'A1B1C1',
 
    );
    my $data_file = 'GrowthCurve.TXT';
    open my $fh, '<', $data_file;
    my $ms = MultiSkan->new(fh => $fh);
    my $A1 = $ms->A1; # quering well A1

You can use

    my %data = $ms->group_stats(@groups); 

to get the averages and standard deviations for each groups. Well, you can use `my @groups = qw/.../`, but then you lose the ability to comment out the groups you don't want for the final report...

If you want to write the data to a file to be processed by other apps (which usually require the data to be arranged in a column-wise fashion, then you can use this snippet:

    my @time = @{$ms->time};
    @time = map {$_/60} @time;
 
    my %data = $ms->group_stats(@groups);
 
    open my $oh, '>', 'report.txt';
 
    print $oh "time";
 
    for (my $i=0;$i<@groups;$i+=2){
        print $oh "\t$groups[$i]\tStdev";
    }
 
    print $oh "\n";
 
 
    for my $i (0..$#time){
        print $oh $time[$i];
        for (my $g=0;$g<@groups;$g+=2){
 
        print $oh "\t".$data{$groups[$g]}->{average}[$i]."\t".$data{$groups[$g]}->{stddev}[$i];
        }
        print $oh "\n";
    }
 

You can use the following function to draw an overview to check out all the 96 wells in a glimpse.

    $ms->draw_all_curves('all_curves.png');

Or you can draw a selected set of data with averages and error bars...

    my %data = $ms->group_stats(@groups);
    $ms->draw_curves(
        'out_img' => 'curves.png',
        'height'  => 768,
        'width'   => 1024,
        'time'    => \@time,
        'data'    => \%data,
        'parameters' => {
            'min_val' => 0,
            'max_val' => 10,
            ...
        },
    );

Since "draw_curves" uses "Chart::ErrorBars" to draw the curves, you can pass all the valid "Chart::ErrorBars" parameters as part of the "parameters" argument.

SUBROUTINES/METHODS

group_stats

This returns the stats (average and stddev) of the groups:

    my %data = $ms->group_stats(@groups);
 

draw_all_curves

Draws a 96-well overview of all the data:

    $ms->draw_all_curves('all_curves.png');
 

draw_curves

Draws curves for the %data returned from group_stats. you can pass any Chart::ErrorBars parameters as a hash ref under `parameters`:

    $ms->draw_curves(
        'out_img' => 'curves.png',
        'height'  => 768,
        'width'   => 1024,
        'time'    => \@time,
        'data'    => \%data,
        'parameters' => {
            'min_val' => 0,
            'max_val' => 10,
            ...
            },
        );
