The \fIflavor_file\fR is an input file that describes the color, transparency, and size/shape of each atom type. The \fIflavor_file\fR consists of two possible line formats. For spherical particles, the format is: .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 \fIatom_type color alpha diameter\fR .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 where alpha is used to adjust the transparency of the particle. For ellipsoidal particles, the format is: .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 \fIatom_type color alpha diameter_x diameter_y diameter_z\fR .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 Ellipsoidal and spherical line formats can be mixed in the same \fIflavor_file\fR For any atom type not listed in the \fIflavor_file\fR a blue sphere of size 1 is assumed. .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 The \fIdump_file\fR is a LAMMPS trajectory. For atom types specified as spherical in the \fIflavor_file\fR, the \fIdump_file\fR must contain \fItag type x y z\fR as the first columns. For atom types specified as ellipsoidal in the \fIflavor_file\fR, the columns are \fItag type x y z quatw quati quatj quatk\fR.The latter can be gerenated, for example, with the LAMMPS dump_style custom command with the following arguments in order: .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 \fItag type x y z quatw quati quatj quatk\fR .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 The output file is a python file for input to Pymol. This can be viewed from the command line using \fIpymol output.py\fR or by using the \fIrun\fR command from within Pymol. .PD 2 .SH PARAMETERS .PD 1 .TP \fB-b\fR When used with \fB-s\fR, the option will number the filenames based on the frame number. By default, they are numbered consequtively from zero. .TP \fB-f\fR \fImax_frame\fR .PD 0 .TP .PP .PD 1 Do not write more than \fImax_frame\fR frames to the output file. .TP \fB-h\fR Print out the man page for help .TP \fB-i\fR \fIstart_frame\fR \fIskip\fR \fIend_frame\fR .PD 0 .TP .PP .PD 1 Render the specified frame interval inclusive between \fIstart_frame\fR and \fIend_frame\fR. \fIskip\fR gives the number of frames to \fIskip\fR between each rendered frame. A value of 0 outputs every frame between \fIstart_frame\fR and \fIend_frame\fR. The first frame in the dump file is frame 0. .TP \fB-n\fR \fInotice_level\fR .PD 0 .TP .PP .PD 1 Set the degree of program output. Use: .PD 0 .PP .PD 1 .PD 0 .PP .PD 1 \fB-n\fR 0 No output .PD 0 .PP .PD 1 \fB-n\fR 10 Normal program output .PD 0 .PP .PD 1 \fB-n\fR 20 Parameters useful for reproducing the results .PD 0 .PP .PD 1 \fB-n\fR 30 All output .TP \fB-o\fR Do not output the outline for the simulation box. .TP \fB-r\fR \fIellip_res\fR .PD 0 .TP .PP .PD 1 Resolution of ellipsoids in PyMol. The number of triangles per ellipsoid is equal to 2*(\fIellip_res\fR^2). Default is 10. .TP \fB-s\fR Output the results into separate .py files. The filename and extension for the output files is taken from \fIoutput_py_file\fR. .PD 2 .SH AVAILABLE COLORS .PD 1 .PD 0 .PP .PD 1 black .PD 0 .PP .PD 1 blue .PD 0 .PP .PD 1 brown .PD 0 .PP .PD 1 cmyk_blue .PD 0 .PP .PD 1 cmyk_marine .PD 0 .PP .PD 1 deep .PD 0 .PP .PD 1 forest .PD 0 .PP .PD 1 green .PD 0 .PP .PD 1 grey .PD 0 .PP .PD 1 hotpink .PD 0 .PP .PD 1 magenta .PD 0 .PP .PD 1 marine .PD 0 .PP .PD 1 orange .PD 0 .PP .PD 1 purple .PD 0 .PP .PD 1 red .PD 0 .PP .PD 1 slate .PD 0 .PP .PD 1 teal .PD 0 .PP .PD 1 wheat .PD 0 .PP .PD 1 white .PD 0 .PP .PD 1 yellow .PD 0 .PP .PD 1 .PD 2 .SH AUTHORS .PD 1 W.
