   Hi, I am a new user of k-Wave.
   I try to learn it from the example but i face some problems:

   1. How to plot the initial pressure distribution and the sensor mask together as the Homogeneous propagation medium example ?
   (I think plotting the figure could help me confirm the setting of input data in the future. My goal is to design a 3-D model of a needle transducer and simulate wave propagation through a 3-layer medium)

   2. When I followed the Saving Movie Files example,
   the command window showed:
   Error using avi
   Unexpected Error. Reason: Failed to open file
   
   how can I fix it?

   Please help me, thank you.

   Hi jill1820,

   (1) You can access the complete code for all the examples via the MATLAB help browser (see section 1.3 in the k-Wave manual if you can't find it). In this case the line of code is:

   imagesc(kgrid.y_vec*1e3, kgrid.x_vec*1e3, source.p0 + cart2grid(kgrid, sensor.mask), [-1 1]);

   (2) Do you get this error if you run the vanilla example code as provided in the toolbox? What version of MATLAB, OS, and k-Wave are you using?

   Brad.
