MASON_FRAG_SEQUENCING(1) | MASON_FRAG_SEQUENCING(1) |
NAME¶
mason_frag_sequencing - Fragment Sequencing Simulation
SYNOPSIS¶
mason_frag_sequencing [OPTIONS] -i IN.fa -o OUT.{fa,fq} [-or OUT2.{fa,fq}]
DESCRIPTION¶
Given a FASTA file with fragments, simulate sequencing thereof.
This program is a more lightweight version of mason_sequencing without support for the application of VCF and fragment sampling. Output of SAM is also not available. However, it uses the same code for the simulation of the reads as the more powerful mason_simulator.
You can use mason_frag_sequencing if you want to implement you rown fragmentation behaviour, e.g. if you have implemented your own bias models.

SEQUENCING SIMULATION¶
Simulation of base qualities is disabled when writing out FASTA files. Simulation of paired-end sequencing is enabled when specifying two output files.
READ ORIENTATION¶
You can use the --mate-orientation to set the relative orientation when doing paired-end sequencing. The valid values are given in the following.
- FR
- Reads are inward-facing, the same as Illumina paired-end reads: R1 --> <-- R2.
- RF
- Reads are outward-facing, the same as Illumina mate-pair reads: R1 <-- --> R2.
- FF
- Reads are on the same strand: R1 --> --> R2.
- FF2
- Reads are on the same strand but the "right" reads are sequenced to the left of the "left" reads, same as 454 paired: R2 --> --> R1.
