 ### Standalone beamformer
 The standalone beamformer executable is `echoframe-beamformer`. It can read a prepared A matrix and raw RF from disk, process it on the GPU, and store the BF back to disk. Example commandline:
 
-`echoframe-beamformer --a_matrix A_matrix.bin --rf RF.bin --bf BF.bin --pixels 4096 --frames 8192 --samples 16384`
