pixels2um: Add and look up magnification factor "pixels2um"

In vrrenske/shinyspots: Visualization and Analysis of Bacterial Cell Segmentation and Fluorescence Data

Add and look up magnification factor "pixels2um"

Description

Functions to check the pixel to micron conversion factors loaded into bactMAP and to add new conversion factors. The new conversion factors will be saved throughout the running R session.

Usage

getPixels2um()

addPixels2um(pixelName, pixels2um)

Arguments

pixelName	A character string identifying your new conversion factor
pixels2um	A numerical value to convert the pixel values to microns

Value

getPixels2um() and addPixels2um("ConversionName", conversionfactor) both return the currently loaded conversion factors as a list of vectors, where the first item of each vector is the conversionfactor-name and the second item is the numeric conversion factor.

Note

If you don't know your pixel conversion factor, open your original images in FIJI/ImageJ and check the Properties of the image.

## To check the currently loaded pixel conversion factors:
getPixels2um()

## To add your pixel conversion factor to bactMAP:
addPixels2um("MyPixel2um", 0.543)
