Guys....
Got a scenario in which I need to skip parsing the header record while I do an awk.
Does awk has the flexibility to accomplish this?.
If so, how do we do this?.
Thanks !!!

bio::graphics::glyph::whiskerplot
Bio::Graphics::Glyph::whiskerplot(3pm) User Contributed Perl Documentation Bio::Graphics::Glyph::whiskerplot(3pm) NAME
Bio::Graphics::Glyph::whiskerplot - The whiskerplot glyph SYNOPSIS
See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>. DESCRIPTION
This glyph is used for drawing features associated with numeric data using "box and whisker" style data points, which display the mean value, extreme ranges and first and third quartiles (or standard deviation). The boxes drawn by this glyph are similar to <http://www.abs.gov.au/websitedbs/D3310116.NSF/0/3c35ac1e828c23ef4a2567ac0020ec8a?OpenDocument>, except that they are oriented vertically so that the position and height of the box indicates the mean value and spread of the data, and the width indicates the genomic extent of the value. Like the xyplot glyph (from which it inherits the whiskerplot is designed to work on a single feature group that contains subfeatures. It is the subfeatures that carry the score information. The best way to arrange for this is to create an aggregator for the feature. We'll take as an example a histogram of repeat density in which interval are spaced every megabase and the score indicates the number of repeats in the interval; we'll assume that the database has been loaded in in such a way that each interval is a distinct feature with the method name "density" and the source name "repeat". Furthermore, all the repeat features are grouped together into a single group (the name of the group is irrelevant). If you are using Bio::DB::GFF and Bio::Graphics directly, the sequence of events would look like this: my $agg = Bio::DB::GFF::Aggregator->new(-method => 'repeat_density', -sub_parts => 'density:repeat'); my $db = Bio::DB::GFF->new(-dsn=>'my_database', -aggregators => $agg); my $segment = $db->segment('Chr1'); my @features = $segment->features('repeat_density'); my $panel = Bio::Graphics::Panel->new; $panel->add_track(@features, -glyph => 'xyplot', -scale => 'both', ); If you are using Generic Genome Browser, you will add this to the configuration file: aggregators = repeat_density{density:repeat} clone alignment etc Note that it is a good idea to add some padding to the left and right of the panel; otherwise the scale will be partially cut off by the edge of the image. The mean (or median) of the data will be taken from the feature score. The range and quartile data must either be provided in a feature tag named "range", or must be generated dynamically by a -range callback option passed to add_track. The data returned by the tag or option should be an array reference containing the following five fields: [$median,$range_low,$range_high,$quartile_low,$quartile_high] where $range_low and $range_high correspond to the low and high value of the "whiskers" and $quartile_low and $quartile_high correspond to the low and high value of the "box." If $median is undef or missing, then the score field of the feature will be used instead. It may be useful to repeat the median in the score field in any case, in order to allow the minimum and maximum range calculations of the graph itself to occur. See Examples for three ways of generating an image. OPTIONS The following options are standard among all Glyphs. See Bio::Graphics::Glyph for a full explanation. Option Description Default ------ ----------- ------- -fgcolor Foreground color black -outlinecolor Synonym for -fgcolor -bgcolor Background color turquoise -fillcolor Synonym for -bgcolor -linewidth Line width 1 -height Height of glyph 10 -font Glyph font gdSmallFont -label Whether to draw a label 0 (false) -description Whether to draw a description 0 (false) -hilite Highlight color undef (no color) In addition, the alignment glyph recognizes all the options of the xyplot glyph, as well as the following glyph-specific option: Option Description Default ------ ----------- ------- -range Callback to return median, none - data comes from feature "range" tag range and quartiles for each sub feature EXAMPLES
Here are three examples of how to use this glyph. Example 1: Incorporating the numeric data in each subfeature #!/usr/bin/perl use strict; use Bio::Graphics; use Bio::SeqFeature::Generic; my $bsg = 'Bio::SeqFeature::Generic'; my $feature = $bsg->new(-start=>0,-end=>1000); for (my $i=0;$i<1000;$i+=20) { my $y = (($i-500)/10)**2; my $range = make_range($y); my $part = $bsg->new(-start=>$i,-end=>$i+16, -score=>$y,-tag => { range=>$range }); $feature->add_SeqFeature($part); } my $panel = Bio::Graphics::Panel->new(-length=>1000,-width=>800,-key_style=>'between', -pad_left=>40,-pad_right=>40); $panel->add_track($feature, -glyph=>'arrow', -double=>1, -tick=>2); $panel->add_track($feature, -glyph=>'whiskerplot', -scale=>'both', -height=>200, -min_score => -500, -key =>'Whiskers', -bgcolor => 'orange', ); print $panel->png; sub make_range { my $score = shift; my $range_top = $score + 5*sqrt($score) + rand(50); my $range_bottom = $score - 5*sqrt($score) - rand(50); my $quartile_top = $score + 2*sqrt($score) + rand(50); my $quartile_bottom = $score - 2*sqrt($score) - rand(50); return [$score,$range_bottom,$range_top,$quartile_bottom,$quartile_top]; } Example 2: Generating the range data with a callback #!/usr/bin/perl use strict; use Bio::Graphics; use Bio::SeqFeature::Generic; my $bsg = 'Bio::SeqFeature::Generic'; my $feature = $bsg->new(-start=>0,-end=>1000); for (my $i=0;$i<1000;$i+=20) { my $y = (($i-500)/10)**2; my $part = $bsg->new(-start=>$i,-end=>$i+16,-score=>$y); $feature->add_SeqFeature($part); } my $panel = Bio::Graphics::Panel->new(-length=>1000,-width=>800,-key_style=>'between', -pad_left=>40,-pad_right=>40); $panel->add_track($feature, -glyph=>'arrow', -double=>1, -tick=>2); $panel->add_track($feature, -glyph=>'whiskerplot', -scale=>'both', -height=>200, -min_score => -500, -key =>'Whiskers', -bgcolor => 'orange', -range => &make_range, ); print $panel->png; sub make_range { my $feature = shift; my $score = $feature->score; my $range_top = $score + 5*sqrt($score) + rand(50); my $range_bottom = $score - 5*sqrt($score) - rand(50); my $quartile_top = $score + 2*sqrt($score) + rand(50); my $quartile_bottom = $score - 2*sqrt($score) - rand(50); return [$score,$range_bottom,$range_top,$quartile_bottom,$quartile_top]; } Example 3: Generating the image from a FeatureFile The file: [general] pixels = 840 pad_left = 40 pad_right = 40 [contig] glyph = arrow double = 1 tick = 2 [data] glyph = whiskerplot scale = both height = 200 min_score = -500 max_score = 2800 key = Whiskers bgcolor = orange chr1 . contig 1 1000 . . .
