Hi,
Tried that but no luck ! The problem with Tachyon rendering it probably failed to capture color from openGL window. Because the low resolution BMP file created alongwith the DAT file for conversion in fact shows no color, only black and gray. I'm clueless as reinstalling the does not help !  Thanks.

Hi,
  What program are you using to view the resulting BMP Bitmap file?
I'm wondering if that program has some incompatibility with the
bitmap format that Tachyon generates.  You might try rendering to a
24-bit Targa file instead, if you like:
    C:\Program Files\University of Illinois\VMD\tachyon_WIN32.exe
    -aasamples 12 Figure1.dat -format Targa -res 3000 3000 -o Figure1.dat.tga

Cheers,
