  Dear Andy and Robert,

Thanks for your suggestions.
Therefore, on one hand, I have tried with;

1) echo $RAYPATH
. : /usr/local/bin/radiance/lib

2) sudo echo $RAYPATH
. : /usr/local/bin/radiance/lib

(The outputs are the same)

3) urtza at urtza-VirtualBox:/usr/local/bin/radiance/lib$ ls
There appear all Radiance data files and GenericTranslucent20.dat and
rang.cal as well

(The programs are in urtza at urtza-VirtualBox:/usr/local/bin/radiance/bin$ ,
and I think that I have to remove from "bin" directory
GenericTranslucent20.dat and rang.cal, which appears there as well)

I do not know if I have problems with the installation, but I will not use
sudo for user level commands.

On the other hand, (I have changed that material for other one and I have
launched dctimestep). The .xml file, which  they have lent for my PhD, is
obtained by goniophotometer.

1) Ubuntu 14:
  dctimestep -n 8760 photocells.vmx Film3M_145x1297_9142012_t.xml
southeast.dmx Barcelona.smx > illum.dat
   
  Usage: dctimestep DCspec [tregvec]
     or: dctimestep Vspec Tbsdf.xml Dmat.dat [tregvec]


2) Windows 8:

dctimestep photocells.vmx Film3M_145x1297_9142012_t.xml southeast.dmx
Barcelona.smx > illum.dat

fatal - unexpected column count in header

I checked with others files that I got and this files seem similar. 

Thank you very much in advance.
Best regards for you,
Urtza.

  Dear Andy,

I have tried with; 

sudo chmod 664 GenericTranslucent20.dat
sudo chmod 664 rang.cal

  sudo chmod 644 GenericTranslucent20.dat
sudo chmod 644 rang.cal

   sudo chmod 600 GenericTranslucent20.dat
sudo chmod 600 rang.cal

sudo chmod 700 GenericTranslucent20.dat
sudo chmod 700 rang.cal

and the padlock continues anyway (The files there are in
/usr/local/bin/radiance/bin/ and  /usr/local/bin/radiance/lib/, as well).
I have tried with rcontrib and it scripts this anyway:
 
   rcontrib -f /usr/share/radiance/klems_int.cal -b
'kbin(-sqrt(.5),sqrt(.5),0,0,0,1)' -bn Nkbins -m windowglow -I+ -ab 2 -ad
512 -lw 2e-5 sc-vi3M_vmx.oct < sc-vi3M.pts > photocells1.vmx

    rcontrib: fatal - cannot find data file "GenericTranslucent20.dat"

I do not know what happen but I will continue finding an error (that
padlock is very strange). 
Thank you very much.
Best regards,
Urtza.
