DESCRIPTION

Simulate transcriptome 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

--output-format

Choose the output format. Available options are: bam, sam, fastq.gz, fastq. For bam option, --append-id is ignored, considering that the sequence identifier is splitted by blank character, so just the first field is included into the query name column (first column).

--join-paired-ends

By default, paired-end reads are put into two different files, prefix_R[12]_001.fastq(\.gz)?. If the user wants both outputs together, she can pass this option. If the --id does not have the escape character %R, it is automatically included right after the first field (blank separated values) as in id/%R - which resolves to id/1 or id/2. It is necessary to distinguish which read is R1/R2

--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
 %x           sequencing error position
 %R           read 1, or 2 if it is the paired-end mate
 %U           read number
 %r           read size
 %m           read mean
 %d           read standard deviation
 %c           sequence id as chromossome, gene/transcript id

 %s           read strand
 %t           read start position
 %n           read end position
 %a           read start position regarding reference genome ***
 %b           read end position regarding reference genome ***
 %v           structural variation position ***
----------------------------------------------------------------------------
*** specific for structural variation (genome simulation only)

Paired-end specific escape characters

----------------------------------------------------------------------------
 Escape       Meaning
----------------------------------------------------------------------------
 %T           mate read start position
 %N           mate read end position
 %A           mate read start position regarding reference genome ***
 %B           mate read end position regarding reference genome ***
 %D           distance between the paired-reads
 %M           fragment mean
 %D           fragment standard deviation
 %f           fragment size
 %F           fragment strand
 %S           fragment start position
 %E           fragment end position
 %X           fragment start position regarding reference genome ***
 %Z           fragment end position regarding reference genome ***
----------------------------------------------------------------------------
*** specific for structural variation (genome simulation only)
--jobs

Sets the number of child jobs to be created

--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-mean

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

--read-stdd

Sets the read standard deviation if quality-profile is equal to 'poisson'. The quality-profile from database overrides the read-stdd

--number-of-reads

Sets the number of reads desired. This is the default option for transcriptome sequencing simulation

--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 if quality-profile is equal to 'poisson'. Valid values are between zero and one

--quality-profile

Sets the sequencing system profile for quality. The default value is a poisson distribution, but the user can choose among several profiles stored into the database or import his own data. See quality command for more details

--expression-matrix

The expression-matrix entries are found into the database. See expression command for more details
