BPLOT (CCP4: Supported Program)
NAMEbplot - Plot temperature factor by residue
SYNOPSISbplot XYZIN1 foo_in1.pdb XYZIN2 foo_in2.pdb plot foo.plt
DESCRIPTIONThis program is used to plot the temperature factors for residues in the PDB input file using plot84 subroutine library. Average B-factors for main chain atoms are plotted against residue number as a line graph. Average B-factors for side chain atoms are plotted against residue number as a histogram, unless the CROSSES keyword is specified.
The current version calculates the maximum B-value for the chain and adjust the y-axis scale accordingly.
The output meta-file PLOT can then be viewed with XPLOT84DRIVER, or converted to PostScript, Textronix or HPGL with PLTDEV.
The available keywords are:
BMAX, CBMAIN, CBSIDE, COMPARE, CROSSES, MAIN, PLTY, RES1, RES2 , SIDE, TITLE, XSCALE, YSCALE
TITLE <title>Title to appear on the plot
PLTYPlot with the x-axis along the length of the paper (landscape).
By default the picture is drawn with the x-axis along the width of the paper (portrait).
CROSSESPoints for side chains marked with crosses.
By default the points are plotted as a histogram.
COMPARETells the program there are two files to read.
For this option can only plot either main chains or side chains
MAINPlot the B values for the main chain only
(this card or SIDE is compulsory if two files input)
SIDEPlot the B values for the side chains only
(this card or MAIN is compulsory if two files input)
XSCALE <xscale>Set the scale along the x-axis explicitly
Default = 0.85
YSCALE <yscale>Set the scale along the y-axis explicitly
Default = 0.85
BMAX <bmax>The maximum y-axis value on the plot.
If the value you supplied is smaller then the calculated maximum B value for this chain, the supplied <bmax> will not be used.
By default the program scales the plot according to the maximum B value found in the input pdb file.
RES1 <res_beg> <res_end>followed by the chain labels and numbers of the first and last residues to be plotted from xyzin1
eg. RES1 A1 A224
RES2 <res_beg> <res_end>followed by the chain labels and numbers of the first and last residues to be plotted from xyzin2
eg. RES2 A1 A224
CBMAINTreat CB's as main chain atoms.
CBSIDETreat CB's as side chain atoms (default).
INPUT AND OUTPUT FILESXYZIN1 Input coordinates
XYZIN2 Input second coordinate file (optional)
PLOT Plot meta-file for PLTDEV
