The options you mention have never been valid inputs. </p> http://www.k-wave.org/forum/topic/saving-every-10th-frame-in-the-forward-simulation#post-8750 Thu, 11 May 2023 16:23:31 +0000 allim2 8750@http://www.k-wave.org/forum/ <p>Hi, </p> <p>I'm trying to save every 10th sample when running k-wave in the forward propagation using kspaceFirstOrder3D.</p> <p>I noticed record is no longer an input option and was usually paired as follows:</p> <p>record = 10; % Record data every 10 time steps</p> <p>% Run the forward simulation<br /> sensor_data = kspaceFirstOrder3D(kgrid, medium, source, [], sensor, 'Record', record, 'PlotSim', false);</p> <p>----------<br /> alternativly sensor used to also be able to take an integer to record every nth frame with this also has been removed.</p> <p>sensor.record = ceil(t_end/(10*dt)); % set the number of recorded time points<br /> sensor.record_start_index = 10; % set the start index for the recorded time points<br /> sensor_data = kspaceFirstOrder3D(kgrid, medium, source, sensor, input_args{:});</p> <p>------------</p> <p>I get errors for both of the above saying they are not valid inputs anymore.<br /> version released notes show many functions and methods have been depreciated.<br /> <a href="http://www.k-wave.org/documentation/k-wave_release_notes.php" rel="nofollow">http://www.k-wave.org/documentation/k-wave_release_notes.php</a></p> <p>Can you please provide a solution to do the above? </p>
