Tutorial - Open/Save an URX file

This tutorial demonstrates how to open and exisiting URX file, read the content of the file, change some values and save the result to a new URX file.

Python

import pathlib

import ultrasound_rawdata_exchange as urx


# read the input file
dataset = urx.loadFromFile("rca.urx")

# print values
print(dataset.acquisition.description)
print(dataset.acquisition.excitations[0].sampling_frequency)

# change values
dataset.acquisition.description = "Learning to modify values ..."

# save the output file
urx.saveToFile("rca-python.urx", dataset, urx.WriterOptions(False, False, False))

MATLAB

% read the input file
dataset = urx.loadFromFile('rca.urx');

% print values
dataset.acquisition.description
dataset.acquisition.excitations(1).samplingFrequency

% change values
dataset.acquisition.description = "Learning to modify values ...";

% save the output file
urx.saveToFile('rca-matlab.urx', dataset, false, false, false)
