Title : value Usage : $val = $ftr->quantitation() Function: get/set the feature's quantitation Returns : A numeric value Args : a new numeric value (optional)

quantitation_units()
Title : quantitation_units Usage : $units = $ftr->quantitation_units() Function: get/set the units of the feature's quantitation Returns : A string or undef Args : a new string (optional)

standard_deviation()
Title : standard_deviation Usage : $std_dev = $ftr->standard_deviation() Function: get/set the feature's standard deviation of quantitation() Returns : A numeric value Args : a new numeric value (optional) Comments: no calculation is done here

sample_count()
Title : sample_count Usage : $sample_count = $ftr->sample_count() Function: get/set the number of samples used to calculate quantitation() Returns : An integer Args : a new integer (optional)
