Hello Thomas, thankyou for your response again. I'm not sure who Klaus Schurman is, but i accessed the website for the company you mentioned and i will try downloading a trial version. thanks again, jon | ||

Dear Jon, the name of the software is Panorama. We are distributing in France from the provider Labcognition. Ask Klaus Schurman if its software could be available in Australia. But you will see that it's much much helpfull and efficient than Unscrambler or other software like it. waiting for your comments Kind regards Thomas Ricour | ||

Thankyou everyopne for your responses. thomas- i would be interested to hear what the name of the software is that you are using. my email address is: [email protected] Bruker does have the IDENT software that can be used for qualitative analysis, but i was told that it's capabilities were a bit limited as we want to do a discriminant analysis-and we would have to buy that software anyway Tony-I have managed to get the spectra out of OPUS in a variety of possible formats, eg. data point file, pirouette.DAT, ENVI, galactic, JCAMP. This is done before PCA though so i'm hoping it is o,k, to export them to other packages in one of these formats. I also assume that once these files are imported into a package(e.g. unscrambler) all of the preprocessing procedures and wavelength selection can be carried out from there. Any suggestions would be appreciated. jon | ||

Hello Guest, The first answer is "yes". People have replicated Fisher's classic experiment using canonical variate analysis to discriminate varieties of mint (but with NIR data) but I cannot recall it being applied to trees. I expect it will work. Software Unscrambler has SIMCA, which I do not like. I beleive that Piroette has a good range of discrimination software but you may need to get your NIR data out of the instrument package - prefereably after PCA. Then you would be able to utilise the software you need in many general statistical packages. Advice: Keep asking questions but first do a search to see what is in the archive of this group. (Utilities menu to the left of your screen). Best wishes, Tony | ||

I thought Bruker had a software module called Ident that could be used to classify samples. Have you tried that and does it work well? | ||

Dear Sir, we are proposing in France but it could be avaible abroad, a software wich can provide you all the quantitavive or qualitative calibrations you need even on HPLC, CPG, UV/Visible, IR... This is much better than unscrambler and easier to use. At this time we are using it to make calibrations for NIR AOTF instead of Unscrambler. | ||

hello, i was wondering if anyone new any good references where people have identified plant hybrids using NIRS or classified spectrally different populations- i have found one paper that has identified Betula hybrids and papers by Richardson that look at finding spectral differences between different populations and species.I have found papers classifying wheat varieties and coffee but wondering if there is anything out there for tree species. I'm also wondering whether anyone can recommend any software that i can use for PCA, DA etc. The Bruker software i am using will only carry out quantitative analysis. I have been told that unscrambler is pretty good. Does anyone have any suggestions? I have just started a phd using NIRS, so any general advice would be much appreciated! |
