Design Type

Overview

Design type identifies type of a trial design.

Some examples:
  1. Randomised Block using DiGGer 
    • The trial design of this design type is generated by the DiGGer.
  2. Unknown Design Type

Detail

Unknown Design Type

The DesignType table has a record for Unknown Design Type (Design Type Name = Unknown Design Type) which can be used when the design type information is not available.

The string value of the "UnknownDesignTypeName" key in the .config file must match the Unknown Design Type record in the Design Type table. Please read important information before making any changes in the config file.
 
  <codeToDatabaseMappings>
    <!-- UNKNOWN Design type -->
        <add key="UnknownDesignTypeName" value="UNKNOWN DESIGN TYPE" />
      </codeToDatabaseMappings> 

Template File for Design Type

The template file is used to generate input file for the trial design software such as DiGGer.
DiGGer Template File
During the trial design creation process, the DiGGer template file is cloned and named as Trial Acronym. Then each of the following tag (including < and > ) are replaced with actual value and the file is feed to DiGGer. 
 
<DiGGer_NoOfTreatments>
    <DiGGer_NoOfRows>
    <DiGGer_NoOfColumns>
    <DiGGer_NoOfRowsPerRep>
    <DiGGer_NoOfColumnsPerRep>
    <DiGGer_BlockBothDirection>
    <DiGGer_GenotypeFormatOfTrialDesignSoftware>

DiGGer processes the file and generate an output file which is used by Import Trial Design to import the trial design in to the database.
