POL  Print-icon

Note: If you are using Excel to edit GenePattern files, be sure to save the file as a tab-delimited text file and supply the correct file extension. You can specify the file name in quotes to prevent Excel from appending .txt to the file name. Also, note that Excel's auto-formatting can introduce errors in gene names, as described in Zeeberg, et al (2004).

POL File Format

The POL file format represents a Parameter-Ordered List. This format is a tab-delimited file with 4 columns, consisting of the following:

  1. A ranking (an integer corresponding to the rank of the feature)
  2. Unique feature identifier
  3. Feature description
  4. Distance metric (value upon which the rank position is based)

If you don't have a distance metric, you can use the rank in column 4 as well. Lines from a sample pol file are shown below:

0	X59798_at	CCND1 Cyclin D1	0.0
1	S69272_s_at	Cytoplasmic antiproteinase	465.5319538
2	U37012_at	Cleavage and polyadenylation specificity factor	493.1997567
3	X69910_at	P63 mRNA for transmembrane protein	493.5331802
4	U53347_at	Neutral amino acid transporter B mRNA	515.3552173
5	M80899_at	AHNAK AHNAK nucleoprotein (desmoyokin)	539.9990741
