gtrack.create_pwm_energy: Creates a new track from PSSM energy function

Description

Creates a new track from PSSM energy function.

Usage

gtrack.create_pwm_energy(
  track = NULL,
  description = NULL,
  pssmset = NULL,
  pssmid = NULL,
  prior = NULL,
  iterator = NULL
)

Value

None.

Arguments

track

track name

description

a character string description

pssmset

name of PSSM set: 'pssmset.key' and 'pssmset.data' must be presented in 'GROOT/pssms' directory

pssmid

PSSM id

prior

prior

iterator

track expression iterator for the newly created track

Details

This function creates a new track with values of a PSSM energy function. PSSM parameters (nucleotide probability per position and pluralization) are determined by 'pssmset' key and data files ('pssmset.key' and 'pssmset.data'). These two files must be located in 'GROOT/pssms' directory. The type of the created track is determined by the type of the iterator. 'description' is added as a track attribute.
