You don't have the authority to "announce" the removal of a feature that is in a GEIA published specification. You may choose to not use it, however, removal from an existing specification is a difficult process. This is why the BIRD process needs to be thorough and complete.

Scott

All,

I announced removal of things like Gaussian and Table for the exact reasons that Danil stated. I did this *many many* moons ago. *Why did no one object at that time?* All decisions that have been made can always be reviewed, but we also need to be practical about it.

Radek,

I believe that since "gausian" keyword was not very clearly defined in the specs, and no developers so far have used it in their AMI files (correct me if I am wrong), the best solution is to remove it from the specs for now. The simpler the spec is, the easier it is for everybody to support it.

Best,

Danil

Walter,

I do not think we can "remove" Gaussian from the specification. It is already there.

As a matter of fact we should try to clarify issues like this one, wherever there is a possibility for misinterpretation.

For Fangyi's question I think the logically correct answer should be the second one:

(PDF 0.0 0.01)

It follows the concept of (/leaf_name value/) where "value" in this case consists of two numbers.

Fangyi,

One of the reasons why I have proposed removing Gaussian as a type in the new BIRD.

Hi, Experts;

If an AMI model has a parameter (PDF (Format Gaussian 0.0 0.01)), what should the Init input parameter string be? Should it be

(PDF Gaussian 0.0 0.01)

or

(PDF 0.0 0.01)

or other format?

Thanks in advance,

Fangyi
