normfluodbf (version 1.5.2)

normfluodatlite: Title: Cleans and normalizes DAT files obtained from experiments using the FLUOstar Omega microplate reader (from BMG LABTECH).

Description

The simplest case scenario entails inputting the name or directory of a DAT file as a string, the number of rows denoted by the tnp (test, negative, positive) parameter, and the number of cycles (selected by the user when running the FLUOstar instrument). The program takes these three baseline parameters, performs cleaning and normalization of the DAT file, and then appends an attribute called “Cycle_Number” to the normalized data frame.

Usage

normfluodatlite(
  dat,
  tnp,
  cycles,
  rows_used = NULL,
  cols_used = NULL,
  user_specific_labels = NULL,
  read_direction = NULL,
  norm_scale = NULL
)

Value

A normalized data frame with an appended "Cycle_Number" attribute. The “Cycle_Number” attribute is the X-variable.

Arguments

dat

A string ("dat_1.dat") if the file is found within the present working directory (pwd) OR a path pointing directly to a ".dat" file.

tnp

A numeric value indicating the number of rows used. TNP is used as an acronym for Test, Negative, Positive.

cycles

A numeric value indicating the number of cycles selected by the user when running the FLUOstar instrument.

rows_used

A character vector of the rows used; ru = c('A','B','C').

cols_used

A numeric vector of the columns used; cu = c(1,2,3).

user_specific_labels

A character vector manually prepared by the user to denote the wells used on the microplate reader; usl = c('A1','B1','C1').

read_direction

A string input with two choices, “vertical” or “horizontal.” The user indicates “vertical” if the user intends to have a final data frame with samples arranged as sample type triplets (A1, B1, C1, A1, B1, C1) OR “horizontal” if the user intends to have a final data frame with samples arranged as clusters per sample type (A1, A2, A3, B1, B2, B3).

norm_scale

This parameter takes sub-parameters: 'raw’ , hundred’ , 'one’ , 'z-score' , or 'decimal’ , which denotes the normalization type or scale; Initialized as NULL.
