Class TXTParser

java.lang.Object

smile.data.parser.microarray.TXTParser

public class TXTParser
extends java.lang.Object

TXT gene expression file parser. The TXT format is a tab delimited file format that describes an expression dataset. It is organized as follows:

The first line contains the labels Name and Description followed by the identifiers for each sample in the dataset. The Description is optional.

Line format: Name(tab)Description(tab)(sample 1 name)(tab)(sample 2 name) (tab) ... (sample N name)

Example: Name Description DLBC1_1 DLBC2_1 ... DLBC58_0

The remainder of the file contains data for each of the genes. There is one line for each gene. Each line contains the gene name, gene description, and a value for each sample in the dataset. If the first line contains the Description label, include a description for each gene. If the first line does not contain the Description label, do not include descriptions for any gene. Gene names and descriptions can contain spaces since fields are separated by tabs.

Line format: (gene name) (tab) (gene description) (tab) (col 1 data) (tab) (col 2 data) (tab) ... (col N data)

Example: AFFX-BioB-5_at AFFX-BioB-5_at (endogenous control) -104 -152 -158 ... -44
