6 Description
|
|
7
|
|
8 gkmertable creates an image showing the abundance of all k-mers
|
|
9 (oligonucleotides of length k) in a given sequence. For example, for
|
|
10 tetramers (k=4), resulting image is composed of 4^4 = 256 boxes, each
|
|
11 representing an oligomer. Oligomer name and abundance is written within
|
|
12 these boxes, and abundance is also visualized with the box color, from
|
|
13 white (none) to black (highly frequent).
|
|
14
|
|
15 This k-mer table is alternatively known as the FCGR (frequency matrices
|
|
16 extracted from Chaos Game Representation).
|
|
17 Position of the oligomers can be recursively located as follows:
|
|
18 For each letter in an oligomer, a box is subdivided into four quadrants,
|
|
19 where A is upper left, T is lower right, G is upper right, and C is lower
|
|
20 left.
|
|
21
|
|
22 Therefore, oligomer ATGC is in the
|
|
23 A = upper left quadrant
|
|
24 T = lower right within the above quadrant
|
|
25 G = upper right within the above quadrant
|
|
26 C = lower left within the above quadrant
