Create new classifications for annotation mode

Creates a classifications data frame with all ROIs set to "unclassified", for use when annotating a sample from scratch.

Usage

create_new_classifications(sample_name, roi_dimensions)

Arguments

sample_name

Sample name (e.g., "D20230101T120000_IFCB134")

roi_dimensions

Data frame from read_roi_dimensions

Value

Data frame with columns: file_name, class_name, score, roi_area

Examples

# Create mock ROI dimensions
roi_dims <- data.frame(
  roi_number = 1:5,
  width = c(100, 150, 80, 200, 120),
  height = c(80, 100, 60, 150, 90),
  area = c(8000, 15000, 4800, 30000, 10800)
)

# Create new classifications (all unclassified)
classifications <- create_new_classifications(
  sample_name = "D20230101T120000_IFCB134",
  roi_dimensions = roi_dims
)
print(classifications)
