   Thanks for all the contributions!

   I was running kspaceFirstOrder3DG using a sensor mask defined by cuboid corners, and I defined the sensors' frequency response.

   Error message popped up when it ran into gaussianFilter, saying that there are "Too many input arguments".

   After some inspection, I found that in kspaceFirstOrder3D, gaussianFilter was applied to sensor data (where sensor_data.p is a 2-D matrix) before re-ordering, so everything was fine.
   However, in kspaceFirstOrder3DG, the sensor data read back from h5 file is already in 4-D format, such that gaussianFilter can not work properly.

   I think I can remove the sensors' frequency response for now and filter the signal after kspaceFirstOrder3DG finishes. Or is there any other alternative modifications that I can do?

   Thanks again!

   P.S. I have modified the h5writeatt part according to http://www.k-wave.org/forum/topic/error-reading-h5-files-when-using-binaries.

   Yes the data will be a 4D array if using cuboid corners. You could instead use a binary sensor mask (so the data will be returned as a 2D array so the call gaussianFilter inside kspaceFirstOrder3DC should work), or apply the filter it after the simulation as you have done.
