[Radiance-general] Errors with 'gendaymtx' and 'dctimestep'

Tue Mar 29 09:29:04 PDT 2016

Hi Greg and Andy,

Thank you for your responses.
I have excluded the '-n 8760' argument from the 'dctimestep' call and it
does not raise the "improper length" error anymore. However, there is a
couple of other errors raised:

OS X Yosemite 10.10.2
Radiance 5.0.8
Command Line Environment: Terminal

Command:

$ dctimestep -if -o hourlypics/back_%04d.hdr viewpics/back_%03d.hdr \
bsdf/fullwindow.xml matrices/daylightmatrix.dmx matrices/OakLand.smx

Error#1

fatal - cannot find BSDF file 'bsdf/fullwindow.xml'

Description:

In the five-phase method tutorial, there are two BSDF files generated in
".xml" format that are named as "fullwindow_klems.xml" and
"fullwindow_t45.xml". There are no BSDF files named "fullwindow.xml". So I
was wondering which
BSDF xml file is meant to be in the command?

Error#2

dctimestep: cannot open 'hourlypics/back_0001.hdr' for output.

Description:

I passed "fullwindow_klems.xml" instead of "fullwindow.xml" just to see if
the command would run into any other errors and the given dctimestep error
about the hourlypics/ directory is raised. I do not see any directory made
in any previous steps of the tutorial that is named "houlrypics". So I do
not understand what the given error is about.

Best Regards,
Alireza
