Re: [Ifeffit] Athena: Target transform function not working

Hi Bruce, No worries on the delay, I totally understand. I've followed your instructions and the Target Transform function is now working. Thanks for the fix! Cheers! On Thu, Oct 17, 2013 at 1:28 PM, Bruce Ravel wrote:

I am trying to use Athena to do some PCA work and am having trouble getting the target transform analysis to work. When I click the target transform button no TT coefficients are produced and only a residual that is shaped like the original spectrum to be transformed is plotted. This seems to happen for all of my standards. (For my data in norm3.prj I am doing the PCA on all the spectra that start with TMF and trying to target transform the other spectra.)

I have also tried this with the cyanobacteria data in the XAS-Education folder (also attached) to ensure it wasn't just a problem with my data. I am still have the same problems with this file as well. The dathena.log file and screenshot come from trying to target transform using this file.

Hi John,

Sorry it took me so long to address this. As I mentioned in my last email, I didn't do much work on the software during the ridiculous US government shutdown which left me furloughed.

This was just a bit of sloppiness on my part. While trying to make some improvements to the PCA part of Demeter, I simply left the target transform function in a non-wroking state. Sorry 'bout that.

It will be fixed in the next release. If you would like to apply the fix imemdiately, you can do so by hand. Do the following:

1. Download https://raw.github.com/**bruceravel/demeter/master/lib/** Demeter/PCA.pmhttps://raw.github.com/bruceravel/demeter/master/lib/Demeter/PCA.pm

2. Save that as C:\strawberry\perl\site\lib\**Demeter\PCA.pm

3. Download

https://raw.github.com/**bruceravel/demeter/master/lib/** Demeter/UI/Athena/PCA.pmhttps://raw.github.com/bruceravel/demeter/master/lib/Demeter/UI/Athena/PCA.p...

4. Save that as C:\strawberry\perl\site\lib\**Demeter\UI\Athena\PCA.pm

Both of those will overwrite existing files.

Be careful that your browser does not change the filename to PCA.tt.txt or some such. The filenames should be exactly as shown.

Note that both files are called PCA.pm, although they live in different folders. Don't get them confused -- they may not be swapped.
