Comment (by annakrat):

 Replying to [ticket:3152 veroandreo]:
 > I want to create an animation for a weekly STVDS covering a total time
 span of 5 years. However, the STVDS only consist of 62 maps, given that
 there's no data in every week but only in those 62 weeks (summer weeks
 over the years).

 > When I pass my STVDS to g.gui.animation (using the GUI or the
 > CLI), I either get a lot of black screens for those time periods in
 which my STVDS has no maps or the last map with data remains there until a
 new map with data comes. Is there a way to only get the background raster
 in those periods without data, instead of the last vector with data???

 I am not sure how do you want it to be? In settings, Time tab there is
 option to not show no data, but I guess that's not what you want. If you
 don't want it to use the time information, load it as series of maps.

 The gui uses python regular expressions, so check what ? means there, it
 works but maybe it has different meaning?

 Thanks, I fixed that, please try again.

 corresponding list of maps. I'm using trunk r69455M under fedora 24.
