Problem with Auto-Freeze

[Franek Dzimira]

Hi,

I'm quite new to Fityk and problem I have might be quite silly, yet I can't find a way thorugh.

My dataset contain one very high peak and another very small. Therefore, when I'm fitting manually, all I do is:

- guess Lorentzian - fit - activate one region where the small peak is - add a baseline - guess Lorentzian and fit. 
With Auto-Freeze it does work fine - I have both Lorentzians properly fitted.

Yet, writing the very same commands in command window leads me to different result - it looks like the first fit was not frozen automatically and therefore result is very inaccurate.

Is there any command I should write in order to Auto-Freeze to work? Or am I making a mistake somewhere else?

Commands:

@*: guess Lorentzian

@*: fit

@*: A = a and not (1.524 < x and x < 1.5396)

%bg2 = Spline(1.535,29.5)

@*: Y = y - %bg2(x)

@*: guess Lorentzian

@*: fit

Best regards,
Franek

Hi,

After using GUI fitting try to save your session history by Session -> Save History

Try to run this fit file by fityk and check the result. If it will be as you want review history file
