Use K-mer Count when you need to count occurrences of an exact k-mer in a DNA sequence with overlapping windows. Enter Sequence and K-mer using the definitions and units below so the result can be reproduced.

Sequence

A sequence, category, or text value.

K-mer

A sequence, category, or text value.

The published tool contract uses this rule: Count occurrences of an exact k-mer in a DNA sequence with overlapping windows.

K-mers found

The calculated k-mers found.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.

Retain the original Sequence and K-mer values and their units alongside the result. Restriction Site Count is useful when you instead need to count non-overlapping occurrences of a restriction site inside a DNA sequence. Codon Count provides another view by helping you count how many complete three-base codons fit in a nucleotide sequence.

• Restriction Site Count

  Count non-overlapping occurrences of a restriction site inside a DNA sequence.

• Codon Count

  Count how many complete three-base codons fit in a nucleotide sequence.

• 3' GC Clamp Count

  Count guanine and cytosine bases among the last three nucleotides of a primer sequence.
