Are there any offline tools which can analyze spectrum from given picture?

Hi Roni - I think I've seen people use MATLAB, for example -- and of course once you download the JSON or CSV or XML, you can use Excel and many other tools. What kind of analysis are you looking to do?

The kits I ordered are in Israel, and I will I will get it tomorrow, so my understanding is based on what I played on site what I read
The input for the system is the file, which is uploaded manually and uploaded to site, or captured using the Interface on site, and then the file is analyzed, displayed and numeric data representing the spectrum can be exported and downloaded. These is the data I need,
but I meed to
1. Automate the process from the point when the picture is captured till I get the numeric data
or
2. Have simple tool which can analyze the picture offline, and produce same numeric data. Tool I can feed with picture and get the data. The tool can be online.
One usage I plan for, is to have for children experiment kit, which will measure data from various sensors, and they will be able to plan experiments and share the data.
For example my kit will measure light level and temperature (easy using today Arduino) and also light spectrum, and they can use to test different street lights and different aspects of light pollution
So what I look for is automating the process, once I have the numeric data for site I can make it accessible to the children with the other data

Hi Rony,
I'm also from Kfar Saba, could try and see if I can help. I guess the nice people in th PL will do they're best to assist, but as open code goes: if you want something which is doesn't exist, make it yourself (then share).

And regarding the issue I asked about, I'm trying to establish what is available and then will need to develop the missing parts. What ever I will develop I will of course share

Hey Rony, it's been a long day at work, will try to call in the coming days, probably over the weekend. I've made a small LabVIEW code (ataced here is a link to the exe file compilation) for analyzing spectrum offline. it's very rudimentary but you can easily use it for offline work.
SW link (~1.1 MB):
I have downloaded a file from the SpectralWorkbench as an example:
you will also need to download and install LabVIEW runtime engine (~500 MB):
Once you do so open the exe file, in it, you can brows for jpg or png files, see them as intensity graph (+RGB data) and save them as csv file (placed the headers at the end of file will be fixed in the next release). I will work on adding other functions similar to the web interface (mainly calibration) when I have the time and based on feedback from members here.

greate Amir, cheers
As I wrote I am just playing around to explore the possibilities
I used your tool to export data from a file I had and the created CSV as input to plot on plotly with additional (dummy data).

I'm not sure I understood why you needed another program to generate the graph, note you can right click on it to export as image. Any way glad to hear I could help!

Eventually I will need to do it offline and give the parsing tool the file to parse as command line parameter so no need to human interversion

Apologies, I was traveling. There is a code snippet linked to at the bottom of the page I linked to: https://gist.github.com/jywarren/4945996
Once you run that (how often do you plan to do that?) you can access them at this feed: http://spectralworkbench.org/spectra/feed/rsegoly
Or, if you tag them all with a unique tag, at the URL: http://spectralworkbench.org/tags/uniquetag.json
For example: http://spectralworkbench.org/tags/cfl.json

that's a macro?
Can you walk me through? Where do I put the code?

That's right - you can paste it into a new macro at http://spectralworkbench.org/macros

Sorry for being layman
I pasted the macro and chose it as capture
I started capturing (using my laptop as is)
Does it mean files will be saved automatically? Where?

yes, if you check http://spectralworkbench.org/profile/rsegoly they should begin to show up there. But how often and for how long will you be saving? We'd like to be sure it doesn't overload the server.
Your JavaScript console should display any errors if you see some; the macro hasn't been used in a while so we should double check that it still works.

I will not overload the server, just testing now, then we will discuss how to handle, offline or on site
Currently I capture and let's see if files appear there

Great - paste in a link to your macro and I can help troubleshoot if it doesn't work.

Do I need to change something in the macro?

Ah, the example is set to hourly. So I think you should set it to every 10 seconds for testing.
To run it, go to the capture interface and find the macro in the macros menu.

Sorry, I'm offline at the moment, and haven't had a chance to look. Your macro doesn't seem to exist... i don't see it listed at http://spectralworkbench.org/macros.
But when I paste in my macro and change the interval to 1 second, it does work: http://spectralworkbench.org/profile/warren

What I do not understand is how to include a macro in capture
I cated one and defined it as capture
I started capture and clicked the script button and I get basic script.
I click on it and I get the list of macros including mine
But now what?
