[GRASS-user] help with temporal modules

[Veronica Andreo]

Dear grass-users,

HI! This is my first time writing to the list. I'm really interested in
using the temporal modules for some spatio-temporal analysis of MODIS Cl-a
mapped L3 product, but i can't even run the example in t.create manual page
[0]. I'm using GRASS 7 (r59147, re-compiled yesterday) under Fedora 19.

I'd like to know which are the steps I should follow to start working with
these modules??? Do I need to install some extra package or library???
Here's what I've tried and the messages I got:

GRASS 7.0.svn (ll_wgs84):~ > t.connect -d
Default driver / database set to:
driver: sqlite
database: /home/veroandreo/grassdata//ll_wgs84/PERMANENT/tgis/sqlite.db

GRASS 7.0.svn (ll_wgs84):~ > t.connect -p
driver:sqlite
database:/home/veroandreo/grassdata//ll_wgs84/PERMANENT/tgis/sqlite.db

GRASS 7.0.svn (ll_wgs84):~ > MAPS="map_1 map_2 map_3 map_4 map_5 map_6
map_7"
GRASS 7.0.svn (ll_wgs84):~ > for map in ${MAPS} ; do
>     r.mapcalc --o expr="${map} = rand(0, 10)"
>     echo ${map} >> map_list.txt
> done

.... it creates the maps, of course, but then...

GRASS 7.0.svn (ll_wgs84):~ > t.create type=strds temporaltype=absolute
output=precipitation_daily title="Daily precipitation" description="Test
dataset with daily precipitation"
ERROR: Unable to receiving temporal database metadata.

ERROR: Unable to receiving temporal database metadata.

/home/veroandreo/grassdata//ll_wgs84/PERMANENT/tgis/sqlite.db

I've noticed there are 2 slashes in
"/home/veroandreo/grassdata*//*ll_wgs84/PERMANENT/tgis/sqlite.db"
--> tried changing that by defining it with t.connect, but when i run the
example gain, I got the same messages as before...

What am I doing wrong? or what am I lacking here??? Would you please help
me???

THANKS A LOT IN ADVANCE!
And sorry for making (surely) a very silly question :P
