Hi Rob,
Thanks for your answer.
Yes, it does, and versions printed successfully.
Now, I am trying to investigate how to run radiance using tutorials, which are based on Unix. Can I do them using the radiance (have just installed for Win32) or shall I install the one for Linux?
Regards
Ikrima

Hi Ikrima,
Not really knowing your exact needs, I'll try to answer:

The Daylight Coefficient or a Design Day interpolation annual simulation approaches do not have to be unique to Ray-tracing engines, like Radiance.
Radiosity engines can make use of the same concepts for annual simulation.
Radiosity can often run a single point in time quicker, with other limitations, and so can calculate more coefficients or design days. I am not sure, but I believe Ecotect is providing an interface to Radiance for simulation and maybe has its own sun path and solar shading design tools.

I believe good representative BSDF data, or just a good model of the fenestration system itself, would still be very important to get a good calculation of daylight coefficients (which is as challenging of a calculation as illuminance). Using Radiance based tools is not necessary as there are other Ray-tracing and Radiosity based tools that can do similar calculations. One convenient thing is that the Radiance based tools use this standard XML BSDF definition now which aligns with the Windows 7 software giving greater access to these definitions.
Regards,
Zack

Hi Greg,
Thanks!?
Now, I will try to solve the problem with?/pcompos /(window1_*.hdr,
invalid argument)
C:\Radiance\test\20150505\vmx\images>pcompos -a 10 -b 1 1 1 window1_*.hdr
> al
lwindow1.hdr
window1_*.hdr: Invalid argument
Best wishes!
Urtza.

Hello Christopher,
Thank you for your response.
I think that in the radiance-4.2.2-win32.exe there is not the ximage
program. I usually use RadianceIV.exe program from Ecotect.
C:\Radiance\test\20150505\vmx>ximage window_000.hdr
"ximage" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.
However, I find klems_full.cal file that it has all information about
kbinS and Nkbins.
Now I have 145 .hdr files. They have light source, but the room walls are
black (is it usual?)
In reference to /pcompos,/ window1_*.hdr is invalid argument. Do you know
why?
C:\Radiance\test\20150505\vmx\images>pcompos -a 10 -b 1 1 1
"window1_*.hdr" > al
lwindow1.hdr
window1_*.hdr: Invalid argument
Thank you in advance,
Kind regards,
Urtza.

Hi All,
I have installed radiance from (radiance-4.2-win32.exe<https://github.com/NREL/Radiance/releases/download/4.2/radiance-4.2-win32.exe>); Do I still need to compile radiance from source code after that? Or, it's now ready to be used?
Regards
Ikrima

Hi Ikrima,
If you used that installer, and you let it modify your path for you, then you are ready to run. You can test this by going to a command prompt and typing:
rtrace.exe -version
You should see the Radiance version printed. If you get a "rtrace.exe is not recognized..." error, then your paths are likely not set up correctly.
Having said that, I recommend you try out the latest v5.0 release of Radiance. There are some important bug fixes and new features, including 64-bit Windows binaries. We posted new installers just the other day, here:
https://github.com/NREL/Radiance/releases/tag/5.0.a.3
