convention, but with large files, data access can become less efficient. As a
rule of thumb, use files smaller than 1MB each. To cut a dataset into a new
chunksize, use the Jackseis program which is part of
[Pyrocko](http://emolch.github.io/pyrocko/):
```bash
# cut whole dataset to hour files:
jackseis INPUT_DIR --tinc=3600 --output-dir=OUTPUT_DIR

hour files use: `jackseis INPUT_DIR --tinc=3600 --output-dir=OUTPUT_DIR`

## Configuration file for Lassie, your friendly earthquake detector
##
## Receiver coordinates can be read from a stations file in Pyrocko format:
stations_path: 'stations.txt'
## Receivers can also be listed in the config file, lat/lon and carthesian
## (x/y/z) = (North/East/Down) coordinates are supported and may be combined
## (interpreted as reference + offset). Omitted values are treated as zero.

# - !lassie.Receiver

## all contained waveform files.

- 'data'
