File Formats¤

KymFlow saves analysis results in JSON format alongside CSV data files. The JSON file contains structured metadata from three main dataclasses: OlympusHeader, ExperimentMetadata, and AnalysisParameters. This page documents the structure and fields of these dataclasses.

JSON File Structure¤

When KymFile.save_analysis() is called, it creates a JSON file in the analysis folder (parent folder + '-analysis' suffix) with the following structure:

{
  "olympus_header": { ... },
  "experiment_metadata": { ... },
  "analysis_parameters": { ... }
}

ExperimentMetadata¤

The experiment_metadata section contains user-provided experimental metadata for documenting experimental conditions, sample information, and notes. All fields are optional and have default values.

name display_name default_value description
species Species ""
region Region ""
cell_type Cell type ""
depth Depth None
branch_order Branch Order None
direction Direction ""
sex Sex ""
genotype Genotype ""
condition Condition ""
condition2 Condition 2 ""
treatment Treatment ""
treatment2 Treatment 2 ""
date Date ""
note Note ""

AnalysisParameters¤

The analysis_parameters section stores information about the analysis algorithm used, its parameters, when it was run, and where results are saved. This metadata is saved alongside analysis results for reproducibility.

name display_name default_value description
algorithm Algorithm ""
parameters Parameters ""
analyzed_at Analyzed At None
result_path Result Path None

OlympusHeader¤

The olympus_header section contains acquisition parameters extracted from the Olympus .txt header file that accompanies kymograph TIFF files. All fields have default values to handle cases where the header file is missing.

name display_name default_value description
um_per_pixel um/pixel 1.0
seconds_per_line seconds/line 0.001
duration_seconds Duration (s) None
pixels_per_line Pixels/Line None
num_lines Lines None
bits_per_pixel Bits/Pixel None
date_str Date None
time_str Time None
raw Raw ""
