**Novoalign**

Novoalign is highly accurate program for mapping next-generation sequencing reads to a reference database. (http://www.novocraft.com/). Selected parameters used here are listed here.

------

**Indexing usage**

novoindex options indexfile sequencefiles

------

**Options - Description**

-­k 99

k­mer length to be used for the index. Novoindex will select appropriate values if either of these is not specified. Default value is log4(N/20s) where N is genome size and s step size.

-s 9

step size for the index. Typical values are from 1 to 3, usually defaults to 1 or 2.  Genomes larger than 4Gbp can be indexed using a stepsize > 1, the requirement is N/s less than 4G.

------

**Alignment usage**

 novoalign options

------

**Options - Description**

-d dbname    
  
Full pathname of indexed reference sequence from novoindex

-f read1 read2    

Filenames for the read sequences for Side 1 and 2.

-­t 99

Sets absolute threshold or highest alignment score acceptable for the best alignment.

-g 99

Sets the gap opening penalty. Default 40

-­x 99

Sets the gap extend penalty. Default 6

-­l 99

Sets the minimum number of good quality bases for a read. 

-­H [99]

Hard clips 3' bases with quality &lt;=[99] from reads before aligning them.
