Data format

Required: two csv files for signal and noise, corresponding directories of the npz files.

The csv file contains four columns: "fname", "itp", "channels"

The npz file contains four variable: "data", "itp", "channels"

The shape of "data" variables has a shape of 9001 x 3

The variables "itp" is the data points of first P arrival times.

Note: In the demo data, for simplicity we use the waveform before itp as noise samples, so the train_noise_list is same as train_signal_list here.

python deepdenoiser/train.py --mode=train --train_signal_dir=./Dataset/train --train_signal_list=./Dataset/train.csv --train_noise_dir=./Dataset/train --train_noise_list=./Dataset/train.csv --batch_size=20
