motifcounterOptions {motifcounter} | R Documentation |
This function sets some global parameters for the 'motifcounter' package.
motifcounterOptions(alpha = 0.001, gran = 0.1, ncores = 1)
alpha |
Numeric False positive probabililty for calling motif hits by chance. Default: alpha = 0.001 |
gran |
Numeric score granularity which is used for discretizing the score range. Default: gran = 0.1 |
ncores |
Interger number of cores used for parallel processing, if openMP is available. Default: ncores = 1 |
alpha=0.001 amounts to calling one motif hit per strand by chance in a sequence of length 1000 bp. Decreasing gran will increase number of discrete bins that represent the real-valued score range. This will yield more a accurate score distribution due to less discretization noise, however, it incurs an increase of the computational burden.
