Nam animations can be saved and converted to animated gifs or MPEG movies.
To save the frames of your movie, first start nam with your trace and set it up where you want it to start and adjust other parameters (step rate, size, etc.) Select ``record animation'' in the File menu to start saving frames. Each animation step will be saved in a X-window dump file called ``nam%d.xwd'' where %d is the frame number.
The following shell script (sh, not csh) converts these files into an animated gif:
for i in *.xwd; do xwdtoppm <$i | ppmtogif -interlace -transparent'#e5e5e5' >`basename $i .xwd`.gif; done gifmerge -l0 -2 -229,229,229 *.gif >movie.gif
