simFastqqRunTimes: simFastqqRunTimes: For given values of k and nSeq the function creates
FASTQ files with simulated data, collects k-mer data with the fastqq
function and reports the run times for the data collection.
Description
For each combination of the parameters k and nSeq,
the function writes one FASTQ file and collects the data.
The FASTQ files are equally structured:
Each read contains 17 randomly selected DNA 6-mers.
Therefore the read-length is always 102.
Usage
simFastqqRunTimes(k, nSeq, filedir=".")
Arguments
k
numeric. k-mer sizes which are passed to fastqq.
Default value is 2:15.
nSeq
numeric. Number of simulated reads in FASTQ-file.
Default value is (100, 1000, ..., 10000000).
filedir
character. The output can be placed in a separate
directory. When not existant, the function tries to create 'filedir'.
The function throws an error when writing is not permitted in the given
directory (Could not open file ...).
Value
.
The data frame has four columns: id, k, nSeq and runtime.
Details
The FASTQ files contain the parameter settings inside their filename.
The files are created with 'writeSimFastq'.
