Hello, thank you very much for this useful video. How to solve this problem? ''Fit did not converge. Maximum iteration setting of 200 was reached.'' Kind regards

"Save Theme as..." not found. When I click on the lock-icon on the report sheet as done at 4:43 after I have done the peak fitting, I do not have the option to select "Save Theme as...". I also do not have the options to select "Block Recalculation" and "Ignore Hidden Rows". Does somebody know why that is? What did I do wrong until this point?

[@TheOriginlab]

Hi Linus, Thanks for your question. Regarding "Block Recalculation" and "Ignore Hidden Rows", these are newer features, so your version may not have them. But as for "Save Theme As" this has been around for many versions. Could you please email us at [e-mail] so we can further look into it? Please include the version you are using and your serial number.

@@TheOriginlab Hello, thank you very much for the answer! I found another way to save the theme by clicking the top right arrow in the peak fitting dialog just before closing. This should be the same. Kind regards

How did you define FWHM? When I apply lower bound as 20, upper as 100, I can't see my fitting peaks anymore.

How did u fix FWHM for your data ?

[@abbashadjabbas]

Can we fitting the FTIR Spectra with transmittance like this method or there is another method?

[@TheOriginlab]

Yes, the Peak Analyzer tool can identify and fit negative peaks too.

after Baseline Treatment the graph disappeared! How to solve this problem?

[@TheOriginlab]

Is it because you didn't check Auto Rescale on Baseline Treatment page? Try Ctrl+R to rescale the axis range. Thanks.
