)

Arguments

lfdcs_file

The autodetections generated by export_autodetections

raven_file

The desired name (.txt) of the Raven selection table

audio_start_time

String giving the audio start time (YYYY-mm-dd HH:MM:SS)

lfdcs_start_time

String giving the lfdcs start time (YYYY-mm-dd HH:MM:SS)

call_types

A vector of desired call types

max_mdist

A numeric value indicating the maximum Mahalanobis distance to export

t_buff

The time buffer (in seconds) that is added to the start and end of each selection. This helps make the selection more visible in Raven.

f_buff

The frequency buffer (in Hz) that is added to the top and bottom of each selection. This helps make the selection more visible in Raven.

Details

The Low-Frequency Detection and Classification System (LFDCS) automatically detects marine mammal vocalizations in large datasets. This script converts a csv file of LFDCS autodetections (extracted from raw detector output using 'export_autodetections') into a text file that can be imported into Raven Pro as a selection table.
