Hi All,
Did any one come across below error from the sky matrix file, while executing the dctimestep?
dctimestep -n 8760 Geometry/vmx/photocells.vmx 2011-SA5.XML matrices/south.dmx mannheim.smx > matrices/Satine_Dark_Grey_White.dat
fatal - unexpected EOF reading mannheim.smx
I created smx file with gendaymtx with out any error.
If i use a sky vector then i don’t see any error.
Is it some thing to do with the time steps and header in smx file?
It would be great if some one could help me. Incase if you want to try it out ,here <https://seafile.rlp.net/d/9ccd83f3c24141709aa7/> are the files.
Best Regards,
Raghu
Hello Raghu,
It has been a while since the last time I played with the 3-phase method,
so I forgot what error message appears when. However, you might want to
check two things:
- That your Sky Matrix and your Daylight matrix were created with the
same number of patches in the sky. Your Daylight Matrix was created using
MF-4, so your skymatrix should be created using --> gendaymtx -m 4
WEATHER.wea > mannheim.smx
- Check that your weather tape has, indeed, 8760 lines.... I am not sure
the -n 8760 options is still needed in dctimestep, though.
Hope this helps!

Hi Germán,
Thanks for the reply. I wondered about this initially, and tried this with several other climate files, the error was the same. Yes the epw and wea has 8760 lines. Also i generated the sky matrix with -m 4 option and it generated a huge smx file about 200mb.
Best Regards,
Raghu

Yes.... smx files are huge. You could think on, instead of storing them,
just piping it to dctimestep, so you save storage.
gendaymtx -m 4 WEATHER.wea | dctimestep V T D > results
Maybe you can try deleting the -n option in dctimestep...?
You can allways use RMTXOP program as well.
Kind regards

In dctimestep manual it asks to put -n when the sky matrix file doesn’t have the no of columns in the header .Since my smx file has 8760 columns in the header , i tried removing -n option and it says 'fatal - unexpected column count in header’.
May be i should give a try with RMTXOP. Thanks for the information Germán .

Just sharing this with the mailing list to say that the issue was resolved, and there's nothing wrong with dctimestep or the 3-phase method other than the fact that it's all very confusing.
Cheers,

Thanks Greg. It is working. I did a mistake initially putting -n 8760 which threw the EOF error and then changed the SMX file, which was created with Tregenza patches, then it threw column count error. Sorry for the confusion.
Thanks again for the patience and looking into the problem.

Hi Raghu,
I ran the command:
dctimestep photocells.vmx 2011-SA5.XML south.dmx frankfurt.smx > results.txt
using the 5.1 release of Radiance and got the attached result.
What system are you using, and which version of Radiance are you running. (I.e., what does "rpict -version" say?) I don't really understand where your error is coming from, as the files appear to be OK.

Hi Raghu,
Can you send me all of your matrices (compressed) and the commands that created them if they are not in the headers? If they are too big for e-mail, perhaps you can post them on a website.
