+The *create samples file* module is used to generate the *samples file* input file for the metaQuantome workflow. This input file is used to specify the column names used for each experimental group. These column names are referenced when handling the input data and performing statistical analysis. An example file is shown below.

 1. **Specify Samples** You may specify the samples by providing the group names (ex: NS *no sucrose* and WS *with sucrose*) and each of their affilated column names (ex: X737WS, X737NS, etc...) from the input files (e.g., peptide intensity *int.tab*). 
 
-2. **Select samples from existing file's header** Alternatively, you can indicate the column indices of the selected headers for each experimental group (ex: columns 1, 3, and 5 for NS; columns 2, 4, and 6 for WS). You need to specify which file from the history you are referencing. An example is shown below.
