Python API

import quakeio

# Read event
csmip_event = quakeio.read("event.zip")

## Extract record and rotate
record = rec = csmip_event["bent_4_north_column_grnd_level"]
angle = 21/7
record.rotate(angle)

## Extract rotated series
series = record['tran'].accel

# Write output
quakeio.write("out.txt", series, write_format="opensees")
