NAME
InSilicoSpectro::InSilico::RetentionTimer - A base class for implementing a peptide retention time predictor
SYNOPSIS
use InSilicoSpectro::InSilico::RetentionTimer;
# create a retention time predictor
my $rt = InSilicoSpectro::InSilico::RetentionTimer->new;
# predict retention time for a peptide
$rt->predict( peptide=>'ACFGDMKWVTFISLLRPLLFSSAYSRGVFRRDTHKSEIAHRFKDLGE' );
# calibrate the predictor
$rt->calibrate( data=>{calseqs=>\@calseqs,caltimes=>\@caltimes,calmodifs=>\@calmodifs},calibrator=>$ec );DESCRIPTION
InSilicoSpectro::InSilico::RetentionTimer is a base class for predictors of peptides retention time in HPLC. It gives also a method for calibration of the predictor.
FUNCTIONS
count_aa()
This function counts the number of ocurrences of each amino acid in a given sequence and returns a reference to an array with the count sorted by the one-letter symbol: ACDEFGHIKLMNPQRSTVWY.
my $count = count_aa( 'AAK' );
print "Found $count[0] Alanines and $count[1] Cysteines\n";METHODS
my $rt=InSilicoSpectro::InSilico::RetentionTimer->new($h)
$h contains a hash with parameters.
$rt->predict($point)
Predict the retention time.
$rt->calibrate(%h)
Calibrate the predictor.
$rt->write_cal( calfile=>$file );
Save current calibrator.
$rt->read_cal ( calfile=>$file );
Retrieve a previously saved calibrator.
$rt->set($name, $val)
Set an instance parameter.
$rt->get($name)
Get an instance parameter.
