To run the program, type:

6 3 Neil Voss
# ./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:
9 1 Neil Voss
10 3 Neil Voss
# ./runPicker.sh

If all works the picker will open up and you'll have two images of ribosomes.

    * Initialize alignment:
55
          o Maximize window
56
          o Set correct zoom for images
57
          o Center the middle bar
58
          o Pick 5 partcle pairs
59
          o Save picks to a file
60
          o Hit the apply button, circles will not match crosses
61
          o Find theta (tilt angle)
62
          o Optimize inplane rotations
63
          o Optimize all parameters
64
          o Mask region to only look at overlapping regions, overlap is shown on status bar
65
          o Hit Auto optimize, it performs find theta, optimize angles and mask in a single click
66
          o If you look at the Terminal it will tell you how many optimization rounds were performed
67
          o Use transfer picks button, this works but is based on the alignment parameters
68
69
    * Auto pick particles
70
          o Measure particle size using ruler tool, zoom in to get best value
71
          o Run DoG picker with wrong contrast
72
          o Reject picks
73
          o Run DoG picker with correct contrast

          o Show terminal
75
          o Accept picks
76
          o Look at DoG map images
77
78
    * Clean up particle picks
79
          o Use clear bad picks button
80
          o Use polygon tool
81
          o Auto optimize
82
          o Use cutoff button to remove picks below a threshold
83
          o Add more picks
