Dear VMD-L,

I have another question regarding the "user field" coloring option in VMD.

After post-processing simulation data, a list of real
numbers were saved in the "beta" field of a regular PDB file.
At the time I mistakenly assumed that the coloring method would
be updated in a per frame basis. After going through the mailing list,
I found a few discussions suggesting the use a external
file to be loaded (via script) in the "user" field but somehow it is not clear
for me how to format this file.

If the PDB file has, let's say, 100 atoms and 20 frames, is it
ok to define a single column file containing 2000 lines (without
white spaces or any other character between frames) to be loaded
in the "user" field ?



Obs. Since all values are already in the "beta" column, would it be
possible to transfer them to the "user" field ? If not, I will just
extract the column to a external file using awk...
