PWM {PWMEnrich} | R Documentation |
A class that represents a Position Weight Matrix (PWM)
id
:a systematic ID given to this PWM, could include the source, version, etc
name
:the name of the transcription factor (TF) to which the PWM corresponds to
pfm
:Position Frequency Matrix (PFM) from which the PWM is derived
prior.params
:Defines prior frequencies of the four bases (A,C,G,T), a named vector. These will be added to individual values for the PFM and at the same time used as background probabilities
pwm
:Final Position Weight Matrix (PWM) constructed using prior.params with logarithm base 2
