PCL_READ - Extract Numeric Data from PCL File

PCL_READ reads a PCL file and writes a copy containing only the numeric data. The main reason for doing this is so that the resulting file can easily be read by a program as pure numeric data.

The PCL files we are considering contain gene expression data from experiments on Arabidopsis. The first line of the file contains a (long) list of labels. There follow N records, each containing 3 labels and 14 numeric values, separated by TAB characters. PCL_READ reads this data, ignoring the title and labels, and writes N records of numeric data to a new file.

Sample usage:

        pcl_read file.pcl file.txt
      

Source code files you may copy include:

• PCL_READ.C, the source code.

PCL files you can copy include:

• i1650.pcl, 180 lines of data.
• i29111.pcl, 1031 lines of data.
• i1039.pcl, 1152 lines of data.
• i2032.pcl, 1481 lines of data.
• i29486.pcl, 8526 lines of data.
• i2282.pcl, 11016 lines of data.

Stripped down copies of the PCL files, created by PCL_READ, include:
