  1. Commands which can be performed using the menu of the RasMol window:

    File Display Colours Options Export
    Open...
    Save as...
    Close
    Exit
    Wireframe
    Backbone
    Sticks
    Spacefill
    Ball and Stick
    Ribbons
    Strands
    Cartoons
    Monochrome
    CPK
    Shapely
    Group
    Chain
    Temperature
    Structure
    User
    Model
    Alt
    Slab Mode
    Hydrogens
    Heteroatoms
    Specular

    Stereo
    Labels
    GIF...
    PostScript...
    PPM...
    IRIS RGB...
    Sun Raster...
    BMP...
    PICT...

    Example) To save a postscript file: go to "Export" - select "PostScript" - type "filename.ps"

  2. Mouse operation (using 3-button mouse):

    • To rotate: use the left mouse button

    • To translate: use the middle mouse button

    • To zoom in or out: use the Shift key + the left mouse button

  3. Commands which can be run on the command line:

    • To measure distance/angle/torsion angle:
      • type "set picking distance", then pick two atoms

      • type "set picking angle", then pick three atoms

      • type "set picking torsion", then pick four atoms

    • To trace the chain:
      1. select *
      2. trace
      3. trace off [turn off trace]

    • To select nucleic acids/proteins only: select [nucleic|protein]

    • To select residues and label, change colors, and highlight them:
      1. select mmm,nnn,ooo,ppp,..., then go to the menu and select "Options - Labels"
      2. color yellow/green/blue/orange/...
      3. wireframe/backbone/ribbons 60/80/200/400/...

      Example 1)
      1. select 500
      2. spacefill 400
      3. color green

      Example 2)
      1. select 500
      2. wireframe 80
      3. color blue

    • To select atoms within a specific distance from a specific residue(s):
      • select within(4.5, nnn)
        Example) select within(8.5, 500)

      • select within(4.5, mmm-nnn)
        Example) select within(30.0, 500-600)

    • To select all atoms in the currently loaded structure:
      • select *
      • select all

    • To select all atoms in a specific chain (A or B or C or ...):
      • select *:a
      • select *:b
      • select *:c

    • To label a specific atom using the E. coli, T. thermophilus, or H. marismortui numbers (this requires you to select positions manually by going through the PDB file and manually interconvert to type in the numbers)"
      1. select atomno=xxx, then
      2. label "nnn"

      Example)
      1. select atomno=1400
      2. label "756"
