=Making a Movie=

Here is a set of steps that can be followed to construct an animated gif (movie) from a set of images that have been constructed using VisTrails.
* Use the "Explore" feature of VisTrails to sample a parameter range and thereby generate a sequences of spreadsheet images.
* After viewing the spreadsheet results, use the spreadsheet's "Export/Separately" menu option to dump the image sequence into a new (otherwise empty) file folder.  By default, VisTrails will name the files:  a1.png, a2.png, a3.png, etc.
* Via the Mac's terminal window, change directories into the folder that contains the image sequence.  Type the following command:
<pre>convert -set delay 3 -colorspace GRAY -colors 16 -dispose 1 -loop 0 -scale 50% *.png Output.gif</pre>
* Related information:
** I initially extracted this recommended "convert" instruction from [http://pages.uoregon.edu/noeckel/MakeMovie.html Jens N&ouml;ckel's web site].
** My Mac contains a manual on this "convert" instruction (man convert); it points out that, "The <b>convert</b> program is a member of the ImageMagick(1) suite of tools."
** The Mac's "convert" manual also refers to a [http://www.imagemagick.org/script/convert.php convert website].

* Finally, simply upload the "Output.gif" file to the VisTrails wiki site, then insert it into the desired wiki page just as you would insert a single image.
