read_dual_pam_single_channel_p700_data: Read and Process DualPAM Data Single Chanel Mode P700

In pam: Fast and Efficient Processing of PAM Data

Read and Process DualPAM Data Single Chanel Mode P700

Description

Reads raw CSV files generated by DualPAM software, calculates electron transport rate (ETR) values for Photosystem I, and returns a universal dataset.

Usage

read_dual_pam_single_channel_p700_data(
  csv_path,
  remove_recovery = TRUE,
  etr_factor = 0.84,
  fraction_photosystem_I = 0.5,
  fraction_photosystem_II = 0.5
)

Arguments

csv_path	File path to the CSV file.
remove_recovery	Logical. Removes recovery measurements if TRUE. Default is TRUE.
etr_factor	Numeric. Factor for ETR calculation. Default is 0.84.
fraction_photosystem_I	Numeric. Relative distribution of absorbed PAR to photosystem I. Default is 0.5.
fraction_photosystem_II	Numeric. Relative distribution of absorbed PAR to photosystem II. Default is 0.5.

Details

Calculates ETR using:

\text{ETR} = \text{PAR} \cdot \text{ETR-Factor} \cdot \text{Fraction of Photosystem (I)} \cdot \text{Yield (I)}

A detailed documentation can be found under https://github.com/biotoolbox/pam?tab=readme-ov-file#read_dual_pam_data

Value

A data.table containing:

• par: Photosynthetically active radiation.

• yield_1: Yield for photosystem I

• yield_2: NA

• etr_1: Calculated ETR for photosystem I

• etr_2: NA
