Origin Ver. and Service Release (Select Help-->About Origin): 9.1.0
Operating System: windows 7

I have 2 problems:

1) I need the height or maximum (and corresponding error) in the parameter table of my Voigt fit. If a go on "code" then "derived parameters" there is FWHM for example, but I cannot type anything in the window to add other parameters..

2) I have to perform this Voigt fit on 25 different spectra, in the same range for each spectrum. How can I do this in a fast way, without fitting every spectrum separately?

Hi,

1) Generally, all the fit parameters has stored in a data tree. You can get the value of a parameter in a tree node. An example can be found on this page:
http://www.originlab.com/doc/LabTalk/guide/Non-linear-Fitting#Script_Example

2) One way to achieve batch processing is to loop over multiple files or datasets. An example can be found on this page:

Hope it helps!
