ifcb_create_empty_manual_file: Create an Empty Manual Classification MAT File

In iRfcb: Tools for Managing Imaging FlowCytobot (IFCB) Data

Create an Empty Manual Classification MAT File

Description

This function was deprecated as it has been replaced by the function: ifcb_create_manual_file().

Generates a MAT file for IFCB data with an empty manual classification structure using a specified number of ROIs, class names, and saves it to a specified output file. This function utilizes a Python script for creating the structure.

Usage

ifcb_create_empty_manual_file(
  roi_length,
  class2use,
  output_file,
  classlist = 1,
  do_compression = TRUE,
  unclassified_id = deprecated()
)

Arguments

roi_length	Integer. The number of rows in the class list (number of ROIs).
class2use	Character vector. The names of the classes to include in the class2use_manual field of the MAT file.
output_file	Character. The path where the output MAT file will be saved.
classlist	Integer or numeric vector. Defines the values for the second column of the class list, typically representing the manual classification labels: If a single value is provided, all rows will be assigned this value. For example, all ROIs can be assigned to class index 1 (default), which typically represents the unclassified category. If a numeric vector of the same length as roi_length is provided, the corresponding values will be used per row.
do_compression	A logical value indicating whether to compress the .mat file. Default is TRUE.
unclassified_id	ifcb_create_empty_manual_file now handles multiple classlist values. Use classlist instead.

Details

The MAT file is written directly from R, producing output identical to the MATLAB ifcb-analysis format. No Python installation is required.

Value

No return value. This function is called for its side effects. The created MAT file is saved at the specified output_file location.

Examples

## Not run: 
# Create a MAT file with 100 ROIs, using a vector of class names, and save it to "output.mat"
ifcb_create_empty_manual_file(roi_length = 100,
                              class2use = c("unclassified", "Aphanizomenon_spp"),
                              output_file = "output.mat")

# Create a MAT file with 50 unclassified ROIs (1) and 50 Aphanizomenon_spp (2) ROIs
ifcb_create_empty_manual_file(roi_length = 100,
                              class2use = c("unclassified", "Aphanizomenon_spp"),
                              output_file = "output.mat",
                              classlist = c(rep(1, 50), rep(2, 50)))
