This page shows how to create an animated GIF from a series of population distribution maps overlaid on a background map, with the year of simulation printed on each.
You need the ImageMagick utility convert.
#!/usr/bin # expects first parameter to be first part of name (will append year and "_prob") # second parameter = start year # third year = end year # Note: you may want to change the text commands! for i in `seq $2 $3` do mapname=${1}${i}_prob d.mon png1 #x0 d.erase d.vect nzcoast_low type=area fcolor=black r.colors map=${mapname} color=byr d.rast $mapname -o d.legend $mapname at=5,50,85,90 d.text at=2,90 size=3 text="B. davidii" d.text text="Null model" at=2,87 size=3 d.text text=$i at=2,93 d.out.png output=$mapname done convert -delay 100 ${1}* ${1}.gif
