Four-way data - parallel
This type of data has the following features:
- It should have 4 + N columns, with the first 4 columns representing Year, Tester (e.g, location), Block (i.e., replication), Entry (e.g., genotype), and followed by N columns of the traits.
- The first row is the header, containing the names of the columns, i.e., Year, "location name", "Block name", "Entry name", and names for each of the N traits. You could put "End" after the trait name, but this is not required if it is an Excel or Access file; it is required only if the data file is in csv data format.
- Each subsequent row contains an observation or entry, wiht values for year, location name, block (replication) name, entry name, and measured value for each of the traits, respectively.
- The data do not have to be balanced in terms of entry by location combinations. The number of blocks can differ for different testers.
- Missing cells can be indicated by anything except that it cannot be left empty for text files.
