GDM provides standard study definitions for several
types of trials. Many corporate clients use customized study
definitions formatted for their data requirements, with dictionaries of
terms recognized by their data management system.
Standard study definitions included with ARM are stored in the GDMdef
subdirectory of ARMdef, such as C:\ARMdef\GDMdef. These “generic” study
definitions begin with “G-” (for GDM). Those study definitions are:
- G-All7.def, for crop protection, crop variety, fertilizer,
and PGR studies
- G-Seed7.def, used for seed variety testing studies when
formulated products are not included as a treatment factor
- G-Gen7.def, for trials that do not use formulated
products, with treatments that are discrete items not separated by rate
values
Standard study definitions included with ARM 6, PRM 5 or 4 are
located in subdirectories of ARMdef\GDMdef. While you may continue to
use the older study definitions, they do not contain all the updated
features/sections included in newer ARM versions. They are also less
compatible with formats used by research sponsors, and thus less
desirable to use for contracted trials.
If you receive customizations from research sponsors, they usually
begin with the company's initials and are stored in a separate
directory. Go to
Contract Researchers for additional information on this topic.
When selecting a study definition while
creating a new protocol, ARM reads a file of default settings for the
selected study definition. This defines initial settings for options
such as plot and mix sizes, number of replicates to randomize, and
experimental design. |
