Process Description

Transpose Wide to Tall

Most of the processes in JMP Genomics software assume that the input SAS data set has a particular data structure. JMP Genomics software distinguishes between tall and wide SAS data sets.

A tall SAS data set has samples as columns, and molecular entity (such as marker, gene, clone, protein, or metabolite) as rows.

A wide SAS data set is the transpose of a tall data set, having the samples as rows and molecular entity as columns.

When specifying the input SAS data set for a process, it is important to know the required form. Most of the processes associated with genetic analyses require a wide structure, whereas most of those for microarray and proteomics analyses use a tall structure.

The Transpose Wide to Tall data set utility transposes a wide SAS data set into a tall SAS data set and generates the Experimental Design Data Set (EDDS) required for subsequent analysis.

What do I need?

One wide data set to be transposed is required.

Output/Results

Running this process generates a tall data set and the associated EDDS.
