Dear Bruce,

I realise you may be travelling soon ,

This is not a very serious bug as I have work rounds.

I was demonstrating linear combination fitting in Athena using the gold thiobacteria example this week.

I am using 9.25 on a windows 7 computer.

I read in all the data from the cynaobacteria project file

I mark  5 or 6 standards

In the LCF tab

I  use marked groups, untick the sum weights to 1 option leaving just the all weights between 0 and 1 option selected.

I pick a sample spectrum eg 4.73

I select fit all combinations

It rolls through them  and reports the apparently correct results but an error message is reported:

Redundant argument in sprint at C:/…  /AppData/Roaming/DemeterPerl/perl/site/lib/Demeter/UI/Athena/LCF.prm line 780, <F> line 122

 

Clicking any of the answers in the combinatorics tab brings up this error again.

 

If I  do a fit of lot of spectra using  the same set of standards, I get a similar  error message except this time it is line 906 and some of the combined spectra don’t plot properly until you refit them as a single spectra in the standards tab

 

I attach a log file but not a project as I assume you can find that on github!

 

Regards

Fred
