sudo recontrib

Dear experts,

I am trying with Three-Phase Method for Simulating Complex Fenestration,
following A McNeil tutorial.

I am using Ubuntu 14 OS. I need use sudo command because I have
GenericTranslucent20.dat material and rang.cal that they are locked anyway.
However, when I have launched sudo rcontrib, it scripts that:

sudo 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 > photocells.vmx

sudo: rcontrib: command not found

Could someone say what the problem is? Thank you in advance.
Best regards,
Urtza.

Dear Urtza,

two comments on your installation - this should be solved before you even start using a complicated combination of commands such as the three-phase method.

First, with a correct configuration of your system you will not need to run rcontrib as super-user (sudo). Your regular user account just needs read-access to the .dat and .cal files in this case, so why would you not grant the proper permissions?

Second, as rcontrib is not found, what makes you think it is installed? Did you install Radiance from sources, did the build complete without errors, and did you include the directory containing the binaries in your PATH environment variable? Does any other Radiance command work for you?

I would recommend having a look at Axel Jacob's set of tutorials first, including the unix-introduction. Otherwise you risk messing up a lot of your models with work-arounds, and even risk the integrity of your system by using sudo where it should definitively not be applied.

Cheers, Lars.

Dear Lars,

Thank you very much for your reply.

I tried with Five-Phase method earlier and all command worked. However, now
I exported the model from Rhino and I have some materials that they need
two specific files. I do not why they do not run without sudo, placing
where there are others, as well (They keep always the padlock, I copy there
from DIVA's files. They are not from radiance package previously
installed). I use oconv, rtrace and rpict with sudo and they work without
problem. Nervertheless, if using sudo is not good I remove those materials
and I could use rcontrib without sudo.

Thank you for your suggestions. I read Axel Jacob's tutorials but rereading
will be fine.
Best regards for you,
Urtza.

Urtza,

You should open up permissions on those two files like so:

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

This changes permissions to allow owner and group read/write and everyone
read.
(you need to be in the directory or give the full path to the file).

A "file not found" error is different from the permissions error you were getting. Do you have your lib directory set in your RAYPATH environment variable? I came in this one late so forgive me if this is redundant but you should have a RAYPATH defined, and it should point to your lib dir (where you should have all the Radiance lib files, such as these dat files and other critical files for Radiance's operation). Most of us also add the current working directory (".") to the PATH and RAYPATH as well. (Your PATH should point to wherever you have the Radiance binaries.)

You should not have multiple copies of everything as it makes it hard to maintain consistency, and makes troubleshooting these kinds of path and permissions errors harder too.

It could be that the directory is not in your RAYPATH, but it is in the RAYPATH for root.

Try:
echo $RAYPATH
sudo echo $RAYPATH

Are there any differences in the output?

Also, it could be that your user doesn't have read permission in the directory containing the files. Try using ls -l on every directory in the path to find out (both lower case L).

As a last resort, I'd copy the files to the working directory, change the owner, permissions, and add "." to RAYPATH. I agree with Lars that I'd never use sudo to run user level commands.

I am using Ubuntu 14 OS. I need use sudo command because I have GenericTranslucent20.dat material and rang.cal that they are locked anyway. However, when I have launched sudo rcontrib, it scripts that:

sudo 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 > photocells.vmx

sudo: rcontrib: command not found

Could someone say what the problem is? Thank you in advance.
Best regards,
Urtza.

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@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@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;

and the padlock continues anyway (The files there are in

I have tried with rcontrib and it scripts this anyway:

   rcontrib -f /usr/share/radiance/klems_int.cal -b

I tried with Five-Phase method earlier and all command worked.
However, now I exported the model from Rhino and I have some
materials that they need two specific files. I do not why they do not
run without sudo, placing where there are others, as well (They keep

_Dear Urtza,

two comments on your installation - this should be solved before you
even start using a complicated combination of commands such as the
three-phase method.

First, with a correct configuration of your system you will not need
to run rcontrib as super-user (sudo). Your regular user account just
needs read-access to the .dat and .cal files in this case, so why
would you not grant the proper permissions?

Second, as rcontrib is not found, what makes you think it is
installed? Did you install Radiance from sources, did the build
complete without errors, and did you include the directory
containing the binaries in your PATH environment variable? Does any
other Radiance command work for you?

I would recommend having a look at Axel Jacob's set of tutorials
first, including the unix-introduction. Otherwise you risk messing
up a lot of your models with work-arounds, and even risk the
integrity of your system by using sudo where it should definitively
not be applied.

Cheers, Lars._

Hi Urtza,
I'm having trouble following what errors we're debugging. Are you okay not
using those materials, because with minimal effort you should be able to
fix it. If you look at the links Lars and I sent you can learn about
permissions and fix the padlock situation.
my comments are inline below.
Best,
Andy

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)

Then I wonder why the files are found when you run with sudo but not found
without sudo. Or am I mis-understanding what is going on.

3) urtza@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@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)

this doesn't help, you need to use the -l (lowercase L) option with ls, as
I orginally suggested, to report the file and directory permissions. And it
would help if you did it for every directory in the path. like this:

ls -l /usr/local/bin/radiance/bin
ls -l /usr/local/bin/radiance
ls -l /usr/local/bin/
ls -l /usr/local/bin/radiance/lib

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

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

The tutorial is outdated. dctiemstep no longer accepts the -n 8760 option.
This info is now contained in the matrix headers. run it again without -n.

Dear Andy,

Thank you very much. Lars's and yours permission suggestions have helped
me.
I checked the directories by ls -l :
Every files have "-rwxrwxrwx 1 root root" permission description except
GenericTranslucent20.dat and rang.cal files; "-rwx------ 1 root root.
I changed the permission by "sudo chmod 777 file" and now the two files
have the same permission as others.
(plugins and /usr/local/bin/radiance and /usr/local/bin/radiance have
"drwxrwxrwx 3 root root" description)

I have launched and now it works. Thanks.
(Note that, I put this two files in my folder with padlock and then I run
with sudo and it works but with rcontrib no. Now, it seems that I put
everything ok and I do not need to do that, which could be not good)

Regarding dctimestep, I remove -n 8760 parameter but it seems that I have
problems with Sky Matrix. The steps have been these:

epw2wea ESP_Barcelona.081810_IWEC.epw Barcelona.wea
  place BARCELONA_ESP
  latitude 41.28
  longitude -2.07
  time_zone -15.00
  site_elevation 6.0
  weather_data_file_units 1
  
  gendaymtx -m 4 Barcelona.wea > Barcelona.smx
  
  dctimestep photocells.vmx Film3M_145x1297_9142012_t.xml southest.dmx
Barcelona.smx > illum.dat
  fatal - unexpected EOF reading Barcelona.smx

I would be very grateful if you could find the problem. Thank you very much
in advance.
Best regards,
Urtza.

Hi Urtza,

glad your materials are finally working.
The most common cause of the error you are receiving is not having the
number of rows in your view matrix. You can use getinfo to look at the
header of your view matrix like this:
getinfo photocells.vmx

is there a line starting with NROWS=

If not, then you can use a text editor to add NROWS=10 (replace 10 with
your number of sensor points). This can be added in the rcontrib command by
adding -y 10

This is one of the many changes in radiance that makes the three phase
tutorial outdated. Sorry.

Andy

Dear Andy,

Thank you very much. Lars's and yours permission suggestions have helped
me.
I checked the directories by ls -l :
Every files have "-rwxrwxrwx 1 root root" permission description except
GenericTranslucent20.dat and rang.cal files; "-rwx------ 1 root root.
I changed the permission by "sudo chmod 777 file" and now the two files
have the same permission as others.
(plugins and /usr/local/bin/radiance and /usr/local/bin/radiance have
"drwxrwxrwx 3 root root" description)

I have launched and now it works. Thanks.
(Note that, I put this two files in my folder with padlock and then I run
with sudo and it works but with rcontrib no. Now, it seems that I put
everything ok and I do not need to do that, which could be not good)

Regarding dctimestep, I remove -n 8760 parameter but it seems that I have
problems with Sky Matrix. The steps have been these:

epw2wea ESP_Barcelona.081810_IWEC.epw Barcelona.wea
place BARCELONA_ESP
latitude 41.28
longitude -2.07
time_zone -15.00
site_elevation 6.0
weather_data_file_units 1

gendaymtx -m 4 Barcelona.wea > Barcelona.smx

dctimestep photocells.vmx Film3M_145x1297_9142012_t.xml southest.dmx
Barcelona.smx > illum.dat
fatal - unexpected EOF reading Barcelona.smx

I would be very grateful if you could find the problem. Thank you very
much in advance.
Best regards,
Urtza.

*Dear Urtza, two comments on your installation - this should be solved
before you even start using a complicated combination of commands such as
the three-phase method. First, with a correct configuration of your system
you will not need to run rcontrib as super-user (sudo). Your regular user
account just needs read-access to the .dat and .cal files in this case, so
why would you not grant the proper permissions? Second, as rcontrib is not
found, what makes you think it is installed? Did you install Radiance from
sources, did the build complete without errors, and did you include the
directory containing the binaries in your PATH environment variable? Does
any other Radiance command work for you? I would recommend having a look at
Axel Jacob's set of tutorials first, including the unix-introduction.
Otherwise you risk messing up a lot of your models with work-arounds, and
even risk the integrity of your system by using sudo where it should
definitively not be applied. Cheers, Lars. *

Hi Urtza and Andy,

I am having the same issue as you do Urtza, I have already checked the
headers of my view matrix, daylight matrix and sky matrix, and that doesn't
seem to be the problem, my view matrix is a 6X145, the daylight matrix a
145X2306, and finally, the sky matrix is a 2306X8760, and this info is on
the headers of each.

I think the problem is in the sky matrix file itself, it's not being
properly written.

Mine looks like this:
#?RADIANCE
gendaymtx -m 4 weather/lisboa.wea
LATLONG= 38.73000000 -9.15000000
NROWS=2306
NCOLS=8760
NCOMP=3
FORMAT=ascii

0 0 0
0 0 0
0 0 0
0 0 0
0 0 0
0 0 0
0 0 0
0.477 0.477 0.477
1.85 1.85 1.85
4.85 4.85 4.85
11.6 11.6 11.6
10.5 10.5 10.5
...

So it doesn't have the number of columns it should, i think that each row
has the RGB value for one patch of one time step and it should have the RGB
values for all time steps of one patch, is that it?

Best regards
Humberto A.

Hi Humberto,

Actually, your header and ASCII data look OK. Although some tools would put all the columns together in one humungous line with 8760x3, white space has no meaning here and gendaymtx output has a newline for each column entry with an extra empty line between rows.

If you run the "wc" command on your file, you should get something like:

  20202873 60601692 xxxxxxxxxxx lisboa.smx

I don't know what xxxxxxx will be, but some large number corresponding to the number of bytes in your file. The first two values may not be exactly this, but should be reasonably close. Otherwise, your file really is missing some data at the end.

If your numbers agree roughly with the above, please send me a gzip'ped copies of your lisboa.wea and the output (*.smx) file in a private e-mail and I will see if I can figure out what is going on.

Cheers,
-Greg

Hi Urtza and Andy,

I am having the same issue as you do Urtza, I have already checked the headers of my view matrix, daylight matrix and sky matrix, and that doesn't seem to be the problem, my view matrix is a 6X145, the daylight matrix a 145X2306, and finally, the sky matrix is a 2306X8760, and this info is on the headers of each.

I think the problem is in the sky matrix file itself, it's not being properly written.

So it doesn't have the number of columns it should, i think that each row has the RGB value for one patch of one time step and it should have the RGB values for all time steps of one patch, is that it?

Following this up on the general mailing list...

The problem was the one Andy pointed out earlier, where the newer version of dctimestep doesn't want the "-n" option when the sky matrix has a header.

Regarding the new question (appearing below), using rmtxop in this way is indeed the simplest means to convert RGB irradiance to illuminance in lux.

Cheers,

I tried to run the command like that and it worked just fine, i got the same results as you did.

I was running the dctimestep command with the -n 8760 option, but this is not needed because the sky matrix already contains that info in the header, running it like you solved the issue.

Now there is just one thing remaining, to convert the RGB values from illum.dat file to illuminance values can i use the command below or is there a better way?

rmtxop -c 47.435 119.93 11.635 results/illum.dat> results/illum_final.dat

Note:
179*0.265=47.436
179*0.670=119.93
179*0.065=11.635

Thanks, Humberto. I ran the following command:

  dctimestep photocells.vmx singleclear.xml south.dmx lisboa.smx > illum.dat

without complaint. I am attaching the result.

Are you sure you have a recent installation of dctimestep? What do you see when you run dctimestep with no arguments? You should get:

Usage: dctimestep [-n nsteps][-o ospec][-i{f|d|h}][-o{f|d}] DCspec [skyf]
   or: dctimestep [-n nsteps][-o ospec][-i{f|d|h}][-o{f|d}] Vspec Tbsdf Dmat.dat [skyf]

Hi Humberto,

Actually, your header and ASCII data look OK. Although some tools would put all the columns together in one humungous line with 8760x3, white space has no meaning here and gendaymtx output has a newline for each column entry with an extra empty line between rows.

If you run the "wc" command on your file, you should get something like:

  20202873 60601692 xxxxxxxxxxx lisboa.smx

I don't know what xxxxxxx will be, but some large number corresponding to the number of bytes in your file. The first two values may not be exactly this, but should be reasonably close. Otherwise, your file really is missing some data at the end.

If your numbers agree roughly with the above, please send me a gzip'ped copies of your lisboa.wea and the output (*.smx) file in a private e-mail and I will see if I can figure out what is going on.

Cheers,
-Greg

Hi Urtza and Andy,

I am having the same issue as you do Urtza, I have already checked the headers of my view matrix, daylight matrix and sky matrix, and that doesn't seem to be the problem, my view matrix is a 6X145, the daylight matrix a 145X2306, and finally, the sky matrix is a 2306X8760, and this info is on the headers of each.

I think the problem is in the sky matrix file itself, it's not being properly written.

Mine looks like this:
#?RADIANCE
gendaymtx -m 4 weather/lisboa.wea
LATLONG= 38.73000000 -9.15000000
NROWS=2306
NCOLS=8760
NCOMP=3

Dear Andy and Greg,

(I am trying to follow Humberto's issue, as well)
I have added to View Matrix sensor points number (I notice that in Daylight
Matrix I have not had NROWS data and I have added NROWS=145). To sum up I
have; Sky Matrix, 2306x8760; Daylight Matrix, 145x2306; and View Matrix,
552x145. I launched dctimestep and it scripts the same error (fatal -
unexpected EOF reading Barcelona.smx).

In case, I review the Sky Matrix with "wc" and I get almost the number that
Greg suggested:

wc Barcelona.smx

20202874 60601692 213155298 Barcelona.smx

I do not know what is the problem with Sky Matrix (although it seems a
little estrange 2306x8760 data are in rows).
Thank you in advance,
Urtza.

Hi Urtza,

Are you running dctimestep with the "-n" option? If yes try to run it
without it. use:

dctimestep view.mtx daylight.mtx transmision.xml sky.mtx

For me this solved the problem, no need for the "-n 8760" option.

Hope it helps.

Best regards
Humberto A.
