+### Testing
+
+There is some test data included in test_data.  You can use it to test the binaries
+created in the previous step.  For example, if you are on windows and followed the steps
+above, your binary will be in `cudaDecon\build\windows-msvc-release\cudaDecon.exe`.
+
+First build an otf:
+
+```sh
+.\build\windows-msvc-release\radialft.exe .\test_data\psf.tif .\test_data\otf.tif --nocleanup --fixorigin 10
+```
+
+Then run the deconvolution:
+
+```sh
+.\build\windows-msvc-release\cudaDecon.exe -z 0.3 -i 10 -D 31.5 .\test_data\ im_raw .\test_data\otf.tif
