Usage

1. Launch the application
2. Select a tab separated .txt file
3. Configure parameters:
   • Upper OD threshold
   • Lower OD threshold
   • Cylinders to analyze (1–8 or all)
4. Run analysis

Input File Requirements

The input must be a tab separated .txt file.

Required structure:

• Column time
• Columns containing .od (optical density)
• Columns containing .pump
• Columns containing .light

Each cylinder must include all three data types.

Cylinder assignment is inferred from naming patterns:

• -1-, -2-, …, -8-

---

Output

Results are written automatically next to the selected input file.

A new folder is created:

results_multicultivator_<input_filename>/

Example:

experiment.txt
results_multicultivator_experiment/

Generated content:

• CSV tables with growth phase statistics
• Interactive HTML plots
• Debug log (only if errors occur)

---

Features

• Growth phase detection from OD data
• Robust Theil–Sen regression
• Duplication time calculation
• Multi cylinder support (1–8 or all)
• Interactive Plotly HTML visualization
• Automatic result export
