| 4 | 3 | Neil Voss | To run the program, type:  | 
| 5 | 1 | Neil Voss | |
| 6 | 3 | Neil Voss | # ./ApTiltPicker.py -1 image1.mrc -2 image2.mrc -p tiltpicks.spi  | 
| 7 | 1 | Neil Voss | |
| 8 | 3 | Neil Voss | 'tiltpicks.spi' is optional. I left an example in the tiltpicker folder. You must run the program in the tiltpicker folder. To run the example type:  | 
| 9 | 1 | Neil Voss | |
| 10 | 3 | Neil Voss | # ./runPicker.sh  | 
| 11 | |||
| 12 | If all works the picker will open up and you'll have two images of ribosomes.  |
