Table 1.

Distribution of k-mer counts found in the breast tumor single-nucleus sequencing data.

k-mer	Size of k-mer space	Observed k-mer space	Reduced space of k-mers
5-mer	4⁵= 1024	1024	1024

10-mer	4¹⁰= 1048576	1048576	1002150

15-mer	4¹⁵= 1073741824	1010206155	749386

20-mer	4²⁰= 1.0995 × 10¹²	5667547542	128425

25-mer	4²⁵= 1.1259 × 10¹⁵	1087589480	11966

Column 1 lists the different "k"s explored. Columns 2 and 3 describe the total number of possible unique k-mers for a given k and the actual number of unique k-mers observed in the data respectively. Column 4 describes the k-mer counts after adjusting for sparsity and amplification noise.
