***********************************
HiFiASM - a fast de novo assembler
***********************************

Hifiasm is a fast haplotype-resolved de novo assembler for PacBio Hifi reads. It can assemble a human genome in several hours and works with the California redwood genome, one of the most complex genomes sequenced so far. Hifiasm can produce primary/alternate assemblies of quality competitive with the best assemblers. It also introduces a new graph binning algorithm and achieves the best haplotype-resolved assembly given trio data.

#### Assembly mode
- *Standard*
- *Trio* When parental short reads are available, hifiasm can generate a pair of haplotype-resolved assemblies with trio binning.

#### Trio Options
- *Haplotype 1 reads* : list of hap1/paternal read names
- *Haplotype 2 reads* : list of hap2/maternal read names
- *Lower bound of the binned k-mer's frequency*
- *Upper bound of the binned k-mer's frequency*

*Bits for bloom filter* (-f) - A value of 0 disables the bloom filter for small genomes. For genomes much larger than human, applying -f 38 or even - f39 is preferred to save memory on k-mer counting.

#### Advanced options
- *Length of adapters to be removed* Old HiFi reads may contain short adapter sequences at the ends of reads. You can specify 20 to trim both ends of reads by 20bp.
- *K-mer length* (must be <64)
- *Minimizer window size*
- *Drop K-mers* K-mers that occur more than this value multiplied by the coverage will be discarded
- *Maximum overlaps to consider* consider up to max(-D*coverage,-N) overlaps for each oriented read
- *Correction rounds* round of correction

#### Assembly options
- *Cleaning rounds* round of assembly cleaning
- *Minimum contig bubble* size Pop contig graph bubbles smaller than this value
- *Minimum unitig bubble* size Pop unitig graph bubbles smaller than this value
- *Tip unitigs* Keep only tip unitigs with a number of reads greater than or equal to this value
- *Maximum overlap drop ratio*
- *Minimum overlap drop ratio*
- *Skip post join contigs step*  disable post join contigs step which may improve N50

#### Options for purging duplicates
- *Purge level* 0: no purging; 1: light; 2: aggressive [0 for trio; 2 for unzip]
- *Similarity threshold for duplicate haplotigs*
- *Minimum overlapped reads for duplicate haplotigs*
- *Coverage upper bound* If not set, this will be determined automatically
- *Experimental high-heterozygosity mode*   enable this mode for high heterozygosity sample NB: May be unstable

#### Hi-C-partition options

- *RNG seed* 
- *Rounds of reweighting Hi-C links* : increasing this may improves phasing results but takes longer time.
- *Rounds of perturbation* : increasing this may improves phasing results but takes longer time.
- *Fraction to flip for perturbation* : increasing this may improves phasing results but takes longer time.

### Outputs

Non Trio assembly
- Haplotype-resolved raw unitig graph in GFA format. This graph keeps all haplotype information, including somatic mutations and recurrent sequencing errors.
- Haplotype-resolved processed unitig graph without small bubbles : Small bubbles might be caused by somatic mutations or noise in data, which are not the real haplotype information.
- Primary assembly contig graph : This graph collapses different haplotypes.
- Alternate assembly contig graph : This graph consists of all assemblies that are discarded in primary contig graph.


Trio assembly
- Haplotype-resolved raw unitig graph in GFA format . This graph keeps all haplotype information.
- Phased paternal/haplotype1 contig graph. This graph keeps the phased paternal/haplotype1 assembly.
- Phased maternal/haplotype2 contig graph. This graph keeps the phased maternal/haplotype2 assembly.
