Solution
Accepted by Sundar...

I tried that zip archive on a different PC and it seemed to work fine. I have recreated and attached again just in case and also provide a 8.6 copy.

 

If there are still problems, please let me know exactly what error you are getting...

 

Cheers,

Hello Ronke, 

 

I did not look at your color source data. However, because the rendering indices are by definition integers and the "Ra" value is an average of the first 8, the resolution cannot be less than 0.125.

 

That being said, while the code is less than perfectly constructed feel free to dig back to where all these things are calculated and remove the "round to nearest" function (located near the output of the aptly-named "Ra Calc.vi"). This will invalidate some of the actual science behind the numbers but will give you your "resolution"...

 

Cheers,

Also, I noticed that the back-save to 8.0 I used in the posted examples actually causes a little problem in the code. Please let me know if you are using the 8.0 files (the 8.6 are perfectly fine).

 

Cheers,

Hi,

 

The spectrum analyse.zip is very useful. Do you have a similar VI (from raw spectrum to color paramters) which provides the dominant wavelength? Is the source code of this program avalable so as I may update it myself? thank you.

Hello all.

 

I realize this is quite an old post, but if anyone has stumbled upon this thread because they have use for spectral analysis and/or composition, please check out the ColorTools package available on the LabVIEW Tools Network. A thorough description and trial of the package are available here: http://interfaceinnovations.org/colortools.html . In addition to a LabVIEW Toolkit, we have executables available for use with LabVIEW RunTime.

 

Please feel free to contact me directly here or at support@interfaceinnovations.org

 

Kind Regards,

Colin
