#3152: g.gui.animation issues with stvds and list of vector maps
-----------------------------+-------------------------
Reporter: veroandreo | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.2.0
Component: wxGUI | Version: svn-trunk
Keywords: g.gui.animation | CPU: Unspecified
Platform: Linux |
-----------------------------+-------------------------
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???
As these are cases of a disease, it has no sense (and it represents
something that it is not true) to keep the last point for an X period of
time until new cases appear.

I thought that maybe only passing the list of 62 maps (not as a time
series) would suffice, but I found I cannot use '?' in the GUI for
the selection, and then I have to manually click on maps with no
possibility to scroll. Is it feasible to add support for
the '?' or a file parameter, as in other modules, to pass a file with the
list of maps?

The next thing I tried was to pass the list of files with the CLI, using

{{{
g.gui.animation vector=`g.list type=vector mapset=.
pattern=cases_20??_??_??_* separator=comma`
}}}

but I get the following error:

{{{
Traceback (most recent call last):
   File "/home/veroandreo/software/grass-7.3.svn/dist.x86_64-pc-linux-
gnu/scripts/g.gui.animation", line 141, in <module>
     main()
   File "/home/veroandreo/software/grass-7.3.svn/dist.x86_64-pc-linux-
gnu/scripts/g.gui.animation", line 112, in main
     layer.cmd = ['d.vect', 'map={name=}'.format(name=vect.split(',')[0])]
KeyError: 'name='
}}}

Listing the maps, however, works as expected, and I get the corresponding
list of maps. I'm using trunk r69455M under fedora 24.

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.

Maybe I was not clear. I'll try better this time. So, I have weekly vector
maps that represent disease cases. These cases appear only in certain
weeks of the year. Then I register my weekly vectors of disease cases as a
STVDS to make use of time information. However, none of the solutions
provided in the animation is optimal to display this kind of data (stvds).
If I choose to display no data time periods, I get black screens when
there are no cases (most of the year). That makes the animation a bit
ugly. On the other hand, if I choose not to display no data time periods,
what I get is the last case that appeared frozen there for most of the
year. And, as I said before, at least for this particular case, that is
not correct nor desirable. It would mean that there's always someone
reporting a disease case in that place, which is not true in the data.

So, dunno if it is possible or not, but what I would expect is to only see
the background raster I choose during those periods with no disease cases,
i.e.: no frozen last vector map, only the raster I add as background.

Well, loading as a list of maps ''kinda'' solves the issue of no data
periods, because I loose time info which was the whole point...

I found the equivalent for '???'. In python reg expressions is
'[0-9][0-9][0-9][0-9]'. I should have tried harder before... but thanks
for the hint

It works now! Thanks much!

makes sense now, could you please close this and create a new enhancement
ticket just with the relevant information? Thank you
