metaQuantome: create samples file

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.

Create samples file

group	colnames
NS	X737NS,X852NS,X867NS
WS	X737WS,X852WS,X867WS

There are two methods for generating this input file:

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 3, 5, and 7 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.

int.tab file

peptide	X737WS	X737NS	X852WS	X852NS	X867WS	X867NS
