pymolshortcuts.py

# -*- coding: utf-8 -*-
'''
DESCRIPTION

    Loads functions that enable faster work in PyMOL.

    To source this script on startup of PyMOL, include the
    following line:

    run pymolshortcuts.py

    This script defines a number of Python functions or shortcts.
    These functions are called shortcuts becasue they are invoked with
    shortnames in analogy to keyborad shortcuts. Unlike keyboard
    entry. The shortcuts are designed to save time and address some
    shortcommings of PyMOL that are annoying like no version control
    for output files.

    The variant of this file called pymolshortcuts.py does not
    depend on Python module beuafitulsoup4 which does not come with
    PyMOL.


INSTALLATION

    Source this file from your pymolrc file on the mac or linux or
    from your pymolrc.pml file on Windows by adding the command
    below (adjust the file path as appropriate) on a separate line:

    run ~/Scripts/PyMOLscripts/pymolshortcuts.py

    Enter "SC" to print to the command history window a list of
    shortcuts.

    You will need to edit the paths to your installation of several
    external applications. See the section "PATHS to Applications"
    below.


REQUIREMENTS

    Should work for PyMOL running with Python 2.7 and 3.7 interpreters.
    Incentive PyMOL built with Anaconda Python3.7 is ideal but not
    essential.

HELP

    To see the documentation for shortcut, enter at the PyMOL prompt:


    help <ShortCutName>

    e.g.,

    help AO

    The documentation for a shortcut includes a 1) description of the
    shortcut, 2) one or more examples of its usage, 3) the corresponding
    PyMOL Macro Language codeas vertical script, 4) the same as a
    horizontal script to ease copying and pasting the code on the
    command line, and 5) the corresponding Python code.

# #################### Edit PATHS to Applications ######################
#
# Find your operating system from the three sets of paths or
# commands below.
# The default OS is Mac.
# If your computer is not a Mac, comment out the Mac set and uncomment
# the set for your operating system.
# Comment out the paths to the applications that you lack.
#
# The paths are for my Mac OS 10.14 with some applications stored in
# /usr/local and some in /opt/local/bin thanks to macports.
# Some paths can be found by entering "which <program>" in a terminal
# window.
#
# You can replace the file path with a command to open the application.
# For example, you can use the command "open -a bbedit" on the Mac.
# This approach is the preferred one: it avoids the spinning ball.
# The analogous command is "start" on Windows.

    More information and examples can be found at:
    http://www.pymolwiki.org/index.php/color_blind_friendly

    DESCRIPTION

        Certain colors are indistinguishable to people with the various forms of
        color blindness, and therefore are better not used in figures intended for
        public viewing.

        This script generates a palette of named colors for PyMOL that are
        unambiguous both to colorblind and non-colorblind people.

        The colors listed here are defined according to recommendations found at
        http://jfly.iam.u-tokyo.ac.jp/html/color_blind/.  This website is a good
        reference to consult when making all kinds of figures, not just those made
        using PyMOL.

        The colors are:

        * cb_black
        * cb_orange
        * cb_sky_blue (also: cb_skyblue, cb_light_blue, cb_lightblue)
        * cb_bluish_green (also: cb_bluishgreen, cb_green)
        * cb_yellow
        * cb_blue
        * cb_vermillion (also: cb_red, cb_redorange, cb_red_orange)
        * cb_reddish_purple (also: cb_rose, cb_violet, cb_magenta)

    USAGE

        CB
        color myObject, cb_red
        color mySel, cb_yellow

    REQUIREMENTS

        None.

        Plain text files can be put under version control.
        Binary and bitmap files should not be put under version control.

      Step 1: initialize repository in current directory
        git init 

      Step 2: make list of binary file types to be ignored (e.g. 
    *.pse
    *.ccp4
    *.mtz
    *.png
    *.dmg
    *.pdf
    *.tiff
    *.jpeg
    *.jpg
    *.zip
    *.tar
    *.rar
    *.jar
    *.iso
    *.7z
    *.o
    *.so
    *.pyc
    *.doc
    *.docx
    *.idtf
    *.u3d
    *.aux
     )
        touch .gitignore
        git add .gitignore
        git commit -m "message" .gitignore

      Step 3: add all other files to repository
        git add .
      Later add new files one at a time
        git add new.pml

      Step 4: commit new files or changes with message
        git commit -m "Edited new.pml."

        or to commit changes to a group of changed files
        git commit -a -m "Changed all *.pml files"

        To automate the process, add the following function to a .bashAliases file in
        your home directory and the source the .bashAliases file from your .bashrc file.
        Then in another terminal window change to the directory with the current pml
        file that you are editing and enter "gcpml new" to save your changes to "new.pml".
        Use the up arrow key to rerun this command as you make changes.  

        # Function to git commit changes to one pml file.
        # Takes the basename as a command line argument. 
        gcpml()

def interface(cmpx, cA='c. A', cB='c. B', cutoff=1.0, selName="interface"):

    DESCRIPTION: 
    Returns a selection of interface residues named according to what you passed into selName.

    USAGE:
    objname, selection1, selection2, cutoff=1.0, selectionNameForInterface


    ARGUMENTS:
    PARAMS
    cmpx
        The complex containing cA and cB

    cA
        The first chain in which we search for residues at an interface
        with cB

    cB
        The second chain in which we search for residues at an interface
        with cA

    cutoff
        The difference in area OVER which residues are considered
        interface residues.  Residues whose dASA from the complex to
        a single chain is greater than this cutoff are kept.  Zero
        keeps all residues.

    selName
        The name of the selection to return.

    EXAMPLE:
    interface 1BRS, c. C, c. F

    MORE DETAILS:
    interfaceResidues -- finds 'interface' residues between two chains in a complex.

    PARAMS
	cmpx
		The complex containing cA and cB

	cA
		The first chain in which we search for residues at an interface
		with cB

	cB
		The second chain in which we search for residues at an interface
		with cA

	cutoff
		The difference in area OVER which residues are considered
		interface residues.  Residues whose dASA from the complex to
		a single chain is greater than this cutoff are kept.  Zero
		keeps all residues.

	selName
		The name of the selection to return.

    RETURNS
	* A selection of interface residues is created and named
		depending on what you passed into selName
	* An array of values is returned where each value is:
		( modelName, residueNumber, dASA )

    NOTES
	If you have two chains that are not from the same PDB that you want
	to complex together, use the create command like:
		create myComplex, pdb1WithChainA or pdb2withChainX
	then pass myComplex to this script like:
		interfaceResidues myComlpex, c. A, c. X

	This script calculates the area of the complex as a whole.  Then,
	it separates the two chains that you pass in through the arguments
	cA and cB, alone.  Once it has this, it calculates the difference
	and any residues ABOVE the cutoff are called interface residues.

    DESCRIPTION: 
    Runs Thomas Holder's quat.py script to generate a biological unit using crystallographic symmetry.
    Requires a pdb file. The defult file type with the fetch command is *.cif.
    When using fetch, add the optional parameter type=pdb.
    Of course, you can also use type=pdb1 to retrieve the biological unit form the PDB. 
    Reads REMARK 350 from the pdb file  `filename` and creates the biological unit (quaternary structure).

    USAGE:
    quat [name [, filename [, prefix]]]

    ARGUMENTS:
    The code for a molecular object with symmetry information. 
    name = string: name of object and basename of PDB file, if filename is not given {default: first loaded object}
    filename = string: file path {default: <name>.pdb}
    prefix = string: prefix for new objects {default: <name>}

    EXAMPLE:

    Control-a moves the cursor to the beginning of the line, even when it is out of view.    
    Up arrow key recalls last line of commands for editing.
    
    These commands may not be available on all systems:
    Shift-control-a selects everything from the right of the cursor to the end of the line.
    Shift-control-e selects everything to the left of the cursor to the end of the line.
    Command-f moves the cursor to the end of the current word.  
    Command-b moves the cursor to the begining of the current word.

     places (two digits to the right of the decimal point) the
     18-element viewing matrix and rewrites the matrix elements
     on a single line with no whitespaces and a semicolon at the
     end. The saved space eases the making of a single line of
     PyMOL commands separated by semicolons. A semicolon 
     with nothing to the right of it at the end of a line of grouped commands
     is harmless.

    You can get a stored view assigned to some
     other digit with the view command) and rounds to two decimal
     places (two digits to the right of the decimal point) the
     18-element viewing matrix and rewrites the matrix elements
     on a single line with no whitespaces and a semicolon at the
     end. The saved space eases the making of a single line of
     PyMOL commands separated by semicolons. A semicolon 
     with nothing to the right of it at the end of a line of grouped commands
     is harmless.

      abstract = {The composition of protein surfaces determines both affinity and specificity of protein-protein interactions. Matching of hydrophobic contacts and charged groups on both sites of the interface are crucial to ensure specificity. Here, we propose a highlighting scheme, YRB, which highlights both hydrophobicity and charge in protein structures. YRB highlighting visualizes hydrophobicity by highlighting all carbon atoms that are not bound to nitrogen and oxygen atoms. The charged oxygens of glutamate and aspartate are highlighted red and the charged nitrogens of arginine and lysine are highlighted blue. For a set of representative examples, we demonstrate that YRB highlighting intuitively visualizes segments on protein surfaces that contribute to specificity in protein-protein interfaces, including Hsp90/co-chaperone complexes, the SNARE complex and a transmembrane domain. We provide YRB highlighting in form of a script that runs using the software PyMOL.},
