# Populates the data/ directory from the download/dir.
|
|
# Does it just for a specific transmitter mode (encoding)
|
|
# Available encodings:
|
|
# AFSK AFSK1k2 AHRPT APT BPSK BPSK1k2 BPSK9k6 BPSK12k5 BPSK400 CERTO CW DUV
|
|
# FFSK1k2 FM FSK1k2 FSK4k8 FSK9k6 FSK19k2 GFSK1k2 GFSK2k4 GFSK4k8 GFSK9k6

# XXX This script removes directories in data/ !!! XXX
|
|
#
|
|
# Usage:
|
|
# wut-dl-sort-txmode [Encoding] [Minimum Observation ID] [Maximum Observation ID]
|
|
# Example:
|
|
# wut-dl-sort-txmode CW 1467000 1470000
|
|
#
|
|
# * Takes the files in the download/ dir.
|
|
# * Looks at the JSON files to see if it is :good", "bad", or "failed".
|
|
# * Hard link it in the appropriate data/ directory.
|
|
# * File is randomly copied to either data/train or data/val directory.
|
|
#
|
|
# Possible vetted_status: bad, failed, good, null, unknown.
