[Radiance-general] Falsecolor and script by csh

[caria.roberto at tiscali.it]

Hi all,
I created a pic file with this comand:

rpict -w-  view.vf -x 1600 -y 1600 -ab 5 -ad 4096 -as 4096 -ar 256 -
aa 0.2-t 60 oct/gensky_sky_$months[$i].$days[$i].$hours[$i].oct > 
pics/lum_gensky_sky_$months[$i].$days[$i].$hours[$i].pic

and everything is fine (I can see the pic and the value are correct)

When I use falsecolor I get a file with 1K size and the tiff comand 
gives me "bad picture:

falsecolor pics/lum_gensky_sky_$months[$i].$days[$i].$hours[$i].pic -
m 179 -s 10000 -l cd/m2 -n 10 > pics/lum_gen_sky_$months[$i].$days
[$i].$hours[$i].fc.pic

#ra_tiff -z  pics/lum_gen_sky_$months[$i].$days[$i].$hours[$i].fc.pic 
tiffs/lum_gensky_sky_$months[$i].$days[$i].$hours[$i].fc.tiff




Another question is about a script and the "if" function; the script 
is showen below:

foreach cloud (5 10 3 4 8 9 7 1 0 6 5)

      if ($cloud <= 3) then
               set sky = "+s"
                       else if ($cloud <= 7 && $cloud >= 4) then
               set sky = "+i"
                        else if ($cloud <= 10 && $cloud >= 8) then
              set sky = "-c"
       endif

      echo $sky
  
 end

It works fine, but if I use a data values, by a text file (data 
values put by one column), I get sintax error: 

set cloud = `cat data_sky/cloud.dat`

set i = 1

while ($i < 10)

echo cloud cover for index $i is $cloud[$i]

set value = `echo $cloud[$1] | cut -d '.' -f 1`
          if ($value <= 3) then
               set sky = "+s"											
          else if ($value <= 7 && $value >= 4) then
               set sky = "+i"
          else if ($value <= 10 && $value >= 8) then
               set sky = "-c"
          
          endif

	echo $sky
    @ i++
 
end

Maybe the if function is not able to read the data values?


Thanks a lot 

Roberto
