Hi,
I am currently working on Peak Fitting Module (PFM) & I am unable to define a user-defined fitting function for originpro 7.5. As I am dealing with metallic peaks, I have to use a function (may be Doniach-Sunjic function) containing asymmetric parameter.
If anyone know about creating a user-defined function in originpro7.5, please help me out in this. I am having a really tough-time regarding this.
Thank you.

Hi goverdhan,

There are a lot of things that can go wrong when trying to define and use a user-defined function with the PFM. I would advise you to contact OriginLab's Tech Support department directly (tech@originlab.com), explain your problem providing as much information as you can about your function, parameters and initialization values, data (a sample dataset would be great), etc. They should be able to help you get going.
