How to treat massive of data in CalcZAF?
« on: January 06, 2021, 07:26:06 PM »
Hello everyone,
Could you explain me, how to treat a lot of experimental points in CalcZAF. I obtained around 100 points (K-raw intensity ratio) for my samples and  I need to calculate weight concentrations from K-raw intensity ratio using different correction methods and compare results.
The explanation how to treat data "point by point" based just on two methods is given in
https://probesoftware.com/smf/index.php?topic=81.0
but I didn't find  any information about treatment of data massive.
Also I need to compare all 10 available methods of correction. How to get the full list of methods?

Thank you so much in advance

Hi Rom,
Not exactly sure what you mean by "treatment of data massive", but once you have a properly formatted input file (did you use the CalcZAF export menu from Probe for EPMA?), just use the CalcZAF Open Input Data File and Calculate/Export All menu.  Then you can calculate your 100 k-ratio measurements and export to Excel in a couple of mouse clicks.  If you want to compare the different matrix correction methods, just perform this operation for each matrix correction method and save to a different file.

In both CalcZAF and PFE you can also select the Use All Matrix Corrections checkbox option. But in CalcZAF it will do the quant calculation for each data point for each matrix correction, while in Probe for EPMA it will perform each matrix correction calculation for all data points and give you the averages also.  Are you working with Ron Rasch? The point being that it would be easier to do this comparison in Probe for EPMA which he can provide to you for data reprocessing.

Also please keep in mind that CalcZAF doesn't perform spectral interference, time dependent intensity (TDI), or area peak factor (APF) corrections, so again, Probe for EPMA would be better for reprocessing. See the Use All Matrix Corrections checkbox in the Analyze! window.

The only stupid question is the one not asked!

Hello, Probeman,
Thank you so much for detailed explanation, it is very useful.
Yes, we are working with Ron Rash, but we are not in the same laboratory.
I will  contact him for further details.
And I have small question for you: could Probe for EPMA software can be installed on separate computer remotely (for processing data), or it should be installed just on computer connected to probe itself?

Thank you so much for your answers.

Hi Rom,
No connection to the probe computer is necessary for re-processing data.

You just need to install CalcZAF and Probe for EPMA on any remote computer, and then copy your MDB probe data file from the probe computer to your remote computer (copy both the .MDB file and the .BIM file if present), to the UserData folder (which will be created the first time you run CalcZAF or Probe for EPMA),  and then you can reprocess all the data from your probe run on the remote computer.

Ron should be able to provide you the .MSI files for installation.  Be sure to update both the CalcZAF and Probe for EPMA apps from the Help menu after installation.

See here for more details and let me know if you have any questions:
