ModelMATCH: Match algorithm to detect TFBS in a sequence

Description Usage Arguments Details Value Author(s) References See Also Examples

View source: R/ModelMATCH.R

Description

Match algorithm is used to construct a PWM model of the intput TFBS sequences. The returned values are the PWM model and the parameters needed to predict using MATCH and the PWM, as the position of the Core, the minimum and maximum scores for a query sequence and its core, the Corecut parameter and the dimensions of teh TFBS matrix.

Usage

1

Arguments

iicc

options of the MEET program

Details

The specific parameters for this detection are: the transcription factor to model and the background probabilities for each nucleotide

Value

output: a list with the model and the parameters

model

logodds matrix using information per site

parametersModel

posCore=position of the core, minim_core=minimum score for the core, maxim_core= maximum score for the core, minim=minimu score, maxim=maximum score, Corecut= percentage of core score that we want to consider, core=logodds for the core, ncolTFBS=dimension of the TFBS matrix
