I, as a new comer to GrassGIS, trying to learn by reading online
instruction and using related dataset. But I find those tutorial are
written for Older Version and thing are not working as such. So, If I
am able to go through with the help of list members, then I will
rewrite or post comments, so that newcomer may take a smoother ride.
So, I request knowledgeable list member to solve following problem.
Thnaks in advance.

I was trying firesimulation data on grass6.2.0RC3, and following
commands never stopped:==========================================
r.spread -vds max=my_ros.max base=my_ros.base dir=my_ros.maxdir
spot_dist=my_ros.spotdist w_speed=wind_speed f_mois=1hour_moisture
start=fire_origin lag=95 backdrop=image_burned output=my_spread
x_output=my_spread.x y_output=my_spread.y
100%Reading inputs ... 100%
Reading fire_origin ... 100%
Finding spread time - number of cells visited in percentage ... 0%That mean. it could not find spread time, this 0% remain 0%.
Do i change some parameter or value in above mentioned command?
The g.region -p showed following information:
=========================
projection: 1 (UTM)
zone: 18
PROJ_INFO file not found for location firedata
datum: ** unknown (default: WGS84) **
ellipsoid: a=6378137 es=0.006694385
north: 4391490
south: 4385100
west: 547000
east: 551890
nsres: 19.96875
ewres: 19.95918367
rows: 320
cols: 245
cells: 78400Is PROJ_INFO file a problem. If yes, how to make it.
Thanks in advance.
