RUNNING THE PROGRAM: ---------------------- To run the program, type: ./ApTiltPicker.py -1 image1.mrc -2 image2.mrc -p tiltpicks.spi '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: ./runPicker.sh If all works the picker will open up and you'll have two images of ribosomes. h2. BUG TRACKING: ---------------------- TiltPicker bugs are now tracked via the AMI redmine server, visit http://emg.nysbc.org/projects/tiltpicker/ to file any bugs h2.
