In Nature40/tRackIT: Process data recorded with automatic radio-tracking stations

filter automatic (tRackIT.OS)

Description

Filtering of raw signals based on transmitter frequency, signal duration and runtime of the transmitter. The function reads files from a given folder. Make shure that there is one file per station and that they have the following columns:timestamp= time of received signal-expected format: “%Y-%m-%d %H:%M:%S (e.g. 1970-01-29 15:30:22:11), duration=signal length of the recorded signal, frequency= frequency in kHz (e.g. 150150.2), max= the max signal strength in dBW of the recorded signal (peak) , receiver= name of the receiver device (usually 0,1,2,3 for a 4 Antenna station ), station= name of the station as character string

Usage

filter_tRackIT(
  animal = NULL,
  freq_er = 2,
  path_to_data = NULL,
  d_min = NULL,
  d_max = NULL,
  start = NULL,
  end = NULL,
  freq = NULL
)

Arguments

animal	list, generated by initanimal function
freq_er	numeric, accepted deviation from tag frequency in khz
path_to_data	string, path to awk filtered file
d_min	numeric, minimum duration of signal
d_max	numeric, maximum duration of signal
start	string, start of tracking YYYY-MM-DD
end	string, end of tracking YYYY-MM-DD
freq	num, tag frequency (khz)
