<div dir="ltr"><div>Dear grass-users,</div><div><br></div><div>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. </div>
<div><br></div><div>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:<br>
</div><div><br></div><div>GRASS 7.0.svn (ll_wgs84):~ > t.connect -d</div><div>Default driver / database set to:</div><div>driver: sqlite</div><div>database: /home/veroandreo/grassdata//ll_wgs84/PERMANENT/tgis/sqlite.db</div>

<div><br></div><div>What am I doing wrong? or what am I lacking here??? Would you please help me???</div><div><br></div><div>THANKS A LOT IN ADVANCE! </div><div>And sorry for making (surely) a very silly question :P</div>
