Fixed vs. Relative

Jmol offers two methods for coloring by temperature value. (For an introduction to the temperature value or B factor, please see Temperature value.)

Other examples:

  • 2zqp 6.0 Å Temperature min/av/max: 328/328/328. Fixed is red; relative is white.
  • 1bdx 6.0 Å Temperature min/av/max: 30/30/30. Fixed is light blue; relative is white.
  • 1qd7 5.5 Å Temperature min/av/max: 0.0/19/102. Fixed & relative seem identical.

Jmol Scripts

The Jmol scripts used by the Temperature 0-10 and Add 10 buttons are:

These scripts require that the main script below be run beforehand.


The following Jmol script produces the above scenes, after loading any PDB file. After running this script, you enter the command "echo pdbID" to display the PDB ID in the upper left. When pasting this script into the Jmol Console (Jmol 11.8 used in Proteopedia in June, 2011), the semicolons were required in order for the echo commands to work properly.

~tempav = {*}.temperature;
~tempmin = {*}.temperature.min;

~tempmax = (~tempmax) % (0);
~tempav = (~tempav) % (0);
if (~tempmin < 1) {~tempmin = (~tempmin) % (1)};
else {~tempmin = (~tempmin) % (0)};

set echo all;

color echo [x00ff00];

set echo echotr 100% 100%;
set echo echotr right;
~report = "Temperature/B values:|Max " + @~tempmax ;
~report += "|Av " + @~tempav + "|Min " + @~tempmin;
echo @~report;

set echo echobl 0% 0%;
echo Fixed;

set echo echotrange 0% 8%;
echo All Atoms

set echo echotl 0% 100%;
