vpr_autoid_read: Read VPR aid files

In vprr: Processing and Visualization of Video Plankton Recorder Data

Read VPR aid files

Description

Read aid text files containing ROI string information or measurement data and output as a dataframe

Usage

vpr_autoid_read(
  file_list_aid,
  file_list_aidmeas,
  export,
  station_of_interest,
  opticalSetting,
  warn = TRUE
)

Arguments

file_list_aid	a list object of aid text files, containing roi strings. Output from matlab Visual Plankton software.
file_list_aidmeas	a list object of aidmea text files, containing ROI measurements. Output from matlab Visual Plankton software.
export	a character string specifying which type of data to output, either 'aid' (roi strings) or 'aidmeas' (measurement data)
station_of_interest	Station information to be added to ROI data output, use NA if irrelevant
opticalSetting	Optional argument specifying VPR optical setting. If provided will be used to convert size data into mm from pixels, if missing size data will be output in pixels
warn	Logical, FALSE silences size data unit warnings

Details

Only outputs either ROI string information OR measurement data

Note

Full paths to each file should be specified
