Genie Global Tunes

This section contains the description of Genie's Global configurations and of their corresponding tunings against public data.

Naming convention

A uniform naming convention is required for all Comprehensive Model configuraion (CMC) and all its derived tunes (Comphensive model Tunes, in short CMT) are identified by a single label. Although an impossibly large of information needs to be encoded in the names, they should remain reasonably short. Not only a CMC name will be a command-line argument for all GENIE applications, a CMC name will be the main vehicle for communicating GENIE model configuration and tune information, often verbally.

It is rather clear that the names of the actual physics models, or the names of the datasets, can not be a part of a uniform and compact naming scheme. Such a naming scheme can only employ “keys” that can be used by users in order to look up the corresponding model configurations, parameter lists and datasets. It is expected that all this information will be maintained in the GENIE web page, and that the subset of that information pertaining to the currently supported CMTs will be included in the GENIE Physics and Users Manual.

A CMC is identified by a 7-charachter string in the form

Gdd_MMv

where
  1. G is a capital letter that identifies the maintainer of the model. The default value is G (for the GENIE collaboration). To avoid ambiguity, GENIE CMCs developed by external groups should use a different naming scheme or, if the same scheme us used, names should start by a character other than G.
  2. dd is a number describing the year during which a CMC was developed.
  3. MM is a number identifying the distinct features of a CMC.
  4. v is a character enumerating small variations to a CMC identified by any given number MM.
Hence, valid examples of CMC names are G18_05p or G17_02a.

Once a CMC is defined, in order to define a tuning, more information is required namely the set of parameters that were tuned and the dataset used to tune the CMC. Therefore the string identifying a CMT is an extension of the CMC in the form

Gdd_MMv_PP_xxx

where
  1. PP is a number identifying the set of parameters that were tuned by the GENIE collaboration. This parameter set is meaningful only in the context of a particular CMC. The number 00 indicates that a CMC has not been tuned by GENIE.
  2. xxx is a number that identifies the dataset used to tune the CMC and estimates the values of the given parameter set. This includes a unique set weights associated with each component dataset. The number 000 indicates that a CMC has not been tuned by GENIE.
Valid examples of CMT codes are G18_05p_00_000 (which is just a CMC) or G17_02a_01_024.
