Donna, the convert line I showed accepts gifs and produces an animated gif without any intermediate pnm files. Since you had mentioned animated gifs in your previous message, I assumed that was the output you were refering to. I do show some examples on the gempak page for producing mpegs- which are different from animated gifs- but since most web browsers now support looping animated gifs, they are what I typically use, eg the lightning animation at: http://www.unidata.ucar.edu/packages/gempak/examples/lightning/lightning.html Imagemagick can accept any number of different input formats and produce a wide range of output formats. In the example I sent you today, the file extension .gif defines that the output would be to a ltgloop.gif gif format file which would be suitable for viewing as an animated gif. I'll update the gempak examples to show how I arrive at the enimated lightning gif file.
