.. class:: infomark

**Purpose**

Meryl is the k-mer counter. It is built into the Celera assembler and is also available as a stand-alone application.
Meryl uses a sorting-based approach that sorts the k-mers in lexicographical order.

In addition of generating count-databases, meryl can perform simple operations on it.

**Basic functions**

The functions that meryl includes are described below: 

    ::

        COUNT OPERATIONS
        - Count: count the occurrences of canonical k-mers
        - Count-forward: count the occurreces of forward k-mers
        - Count-reverse: count the occurreces of reverse k-mers
        FILTERING OPERATIONS
        - Less-than: return k-mers that occur fewer than N times in the input
        - Greater-than: return k-mers that occur more than N times in the input
        - Equal-to: return k-mers that occur exactly N times in the input
        - Not-equal-to: return k-mers that do not occur exactly N times in the input
        ARITHMETIC OPERATIONS
        - Increase: add x to the count of each k-mer
        - Decrease: subsctract x from the count of each k-mer
        - Multiply: multiply the count of each k-mer by x
        - Divide: divide the count of each k-mer by x
        - Divide-round: divide the count of each k-mer by x and round th results
        - Modulo: set the count of each k-mer to the remainder of the count divided by x
        OPERATIONS ON SETS
        - Union-min: return k-mers that occur in any input, set the count to the minimum count
        - Union-max: return k-mers that occur in any input, set the count to the maximum count
        - Union-sum: return k-mers that occur in any input, set the count to the sum of the counts
        - Intersect: return k-mers that occur in all inputs, set the count to the count in the first input
        - Intersect-min: return k-mers that occur in all inputs, set the count to the minimum count
        - Intersect-max: return k-mers that occur in all inputs, set the count to the maximum count
        - Intersect-sum: return k-mers that occur in all inputs, set the count to the sum of the counts
        - Subtract: return k-mers that occur in the first input, subtracting counts from the other inputs
        - Difference: return k-mers that occur in the first input, but none of the other inputs
        - Symmetric-difference: return k-mers that occur in exactly one input

**Additional function: build hap-mers dbs for trios**

In addition of the basic operations, this wrapper allows to build the hap-mers databases for trios, in accordance
with `merqury's recommended guidelines. <https://github.com/marbl/merqury/wiki/1.-Prepare-meryl-dbs#3-build-hap-mer-dbs-for-trios>`_
