Hi,

A couple weeks ago I asked about displaying text in VMD using bash
shell commands. Axel replied that I should use the 'exec' command and
this works. Thank you Axel.

However, now I am having trouble getting it to display in PovRay when
rendering the image.

Here is a snippet of my script

while {$frame <=$lastframe} {
draw delete all
draw color black
set time [exec awk NR==$frame time.txt]
echo "Time = $time ps"
draw text "-100 80 -50" "Time = $time ps" size 2
render POV3 $frame.pov
animate goto $frame
incr frame
}

In the VMD development page
(http://www.ks.uiuc.edu/Research/vmd/vmd-1.9/devel.html), I saw this
"Polished up the text rendering implementations for Tachyon,
LibTachyon, Raster3D, and POV-Ray" for Feb. 10, 2011. I am using the
March 14, 2011 Final release of VMD 1.9.

Can POV-Ray render text and I'm doing something wrong? I also can't
see text in the *pov file that I can tell or when I just write plain
text without any variables.

Thanks.

Josh
