DESCRIPTION

Simulate a custom sequencing.

OPTIONS

--help

Print a brief help message and exits.

--man

Prints the manual page and exits.

--verbose

Prints log information to standard error

--prefix

Concatenates the prefix to the output-file name.

--output-dir

Creates output-file inside output-dir. If output-dir does not exist, it is created recursively

--append-id

Append string template to the defined template id. See Format

--id

Overlap the default defined template id: single-end %i.%U %U and paired-end %i.%U %U e.g. SR123.1 1 See Format

Format

A string Format is a combination of literal and escape characters similar to the way printf works. That way, the user has the freedom to customize the fastq sequence identifier to fit her needs. Valid escape characteres are:

Common escape characters

Escape       Meaning
------       ------------------------------------------
%i   	     instrument id composed by SR + PID
%I           job slot number
%q           quality profile
%e           sequencing error
%R           read 1, or 2 if it is the paired-end mate
%U           read number
%r           read size
%c           sequence id as chromossome, ref
%s           read or fragment strand
%t           read start position
%n           read end position

Paired-end specific escape characters

Escape       Meaning
------       ------------------------------------------
%T           mate read start position
%N           mate read end position
%D           distance between the paired-reads
%m           fragment mean
%d           fragment standard deviation
%f           fragment size
%S           fragment start position
%E           fragment end position

--jobs

Sets the number of child jobs to be created

--gzip

Compress the output-file with gzip algorithm. It is possible to pass --no-output-gzip if one wants uncompressed output-file

--seed

Sets the seed of the base generator. The ability to set the seed is useful for those who want reproducible simulations. Pay attention to the number of jobs (--jobs) set, because each job receives a different seed calculated from the main seed. So, for reproducibility, the same seed set before needs the same number of jobs set before as well.

--read-size

Sets the read size, if quality-profile is equal to 'poisson'. The quality-profile from database overrides the read-size

--coverage

Calculates the number of reads based on the sequence coverage: number_of_reads = (sequence_size * coverage) / read_size

--number-of-reads

Sets directly the number of reads desired. It overrides coverage, in case the two options are given

--sequencing-type

Sets the sequencing type to single-end or paired-end

--fragment-mean

If the sequencing-type is set to paired-end, it sets the fragment mean

--fragment-stdd

If the sequencing-type is set to paired-end, it sets the fragment standard deviation

--sequencing-error

Sets the sequencing error rate. Valid values are between zero and one

--quality-profile

Sets the illumina sequencing system profile for quality. For now, the unique valid values are hiseq and poisson

--strand-bias

Sets which strand to use to make a read. Valid options are plus, minus and random - if you want to randomly calculte the strand for each read

--seqid-weight

Sets the seqid (e.g. chromossome, ensembl id) raffle behavior. Valid options are length, same and count. If it is set to 'same', all seqid receives the same weight when raffling. If it is set to 'length', the seqid weight is calculated based on the seqid sequence length. And finally, if it is set to 'count', the user must set the option --expression-matrix. For details, see --expression-matrix

--expression-matrix

If --seqid-weight is set to count, then this option becomes mandatory. The expression-matrix entries are found into the database. See expression command for more details
