Summarize important info from work loop files stored in the same folder (e.g. a sequence of trials in an experiment) including experimental parameters, run order, and mtime.

summarize_wl_trials(wl_list)

Arguments

wl_list

List of analyzed_workloop objects, preferably one created by read_analyze_wl_dir().

Value

A data.frame of information about the collection of workloop files. Columns include:

File_ID

Name of the file

Cycle_Frequency

Frequency of Position change

Amplitude

amplitude of Position change

Phase

Phase of the oscillatory cycle (in percent) at which stimulation occurred. Somewhat experimental, please use with caution

Stimulus_Pulses

Number of stimulation pulses

mtime

Time at which file's contents were last changed (mtime)

Mean_Work

Mean work output from the selected cycles

Mean_Power

Net power output from the selected cycles

Details

If several files (e.g. successive trials from one experiment) are stored in one folder, use this function to obtain summary stats and metadata and other parameters. This function requires a list of analyze_workloop objects, which can be readily obtained by first running read_analyze_wl_dir() on a specified directory.
