How do I know which study definitions to use?

back

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-Gen7.def, for trials that do not use formulated products, with treatments that are discrete items not separated by rate values
  • G-Seed7.def, used for seed variety testing studies when formulated products are not included as a treatment factor

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.
