Hi Julio;
Seen your reply .However it may clash with PLS tool box works under Matlab .They are also using same data structure format.Hope my friend Rambros might throw some light on it.
I am working for you to find out bugs in your tool .

Hi Venkatarman

There would probably be a conflict with the PLS toolbox as you mentioned, so I renamed the "pls" function to "iroot_pls" and changed all function calls within the library accordingly. Please let me know if something happens if you try to use PLS in IRoot.

Please note that to use PLS (under "Transform..." in datatool), you need to standardize your dataset first (this function is available in "Pre-process.."), i.e., zero mean and unit standard deviation.

Hi Venkatarman

Thanks for your post!

I corrected the problem with the "pls" function. I put a prefix, so it is now called "iroot_pls" (will do the same if similar cases occur).

Regarding the note under "modules", that was only a test, that page has been removed. I will upload a new documentation when have more fixes.

That would be great! There is some wavelet de-noising already (pre-processing). I am not familiar with self-organizing maps but heard about it.

Cheers

First notes under modules .There is a problem it getting notes .Plese check .I am using PLS tool box of eigen vector -Is there clash when installing you GLP software .Since you are using same command pls .Please mail back . Regarding contribution. We are working on Wavelet and SOM .
Once the we get bug free routine we aill back to you . Thanks lot.

LINK CORRECTION
---------------

The link http://bioph.lancs.ac.uk/iroot is working now.

It had a problem for Internet Explorer users.

Hi,

I just finished the website for our MATLAB toolbox at Lancaster University Centre for Biophotonics, UK.

The website is http://bioph.lancs.ac.uk/iroot

We are releasing under the GNU LGPL. Contributors more than welcome!!!

There is a good documentation effort, with sample datasets, demos, step-by-step tutorials and the official documentation generated by Doxygen from the sources.

In terms of tools, it already has a broad coverage, from outlier removal passing through pre-processing, exploratory analysis, classification with cross-validation and many visualization options.

It can also open directly OPUS files, both images (in datatool) and single-spectrum files (in mergetool). Some people in this list manifested their interest in this. Please note that this is thanks to 3rd-party contributors.

If you use it, please help us reporting bugs or malfunction, they will be corrected asap!

Julio - [email protected]
