SFFRead-class: Class '"SFFRead"'

In R453Plus1Toolbox: A package for importing and analyzing data from Roche's Genome Sequencer System

Description

This class is a container for a single read from files in Roche's Standard Flowgram Format (SFF).

Objects from the Class

Objects can be created by calls of the form new("SFFRead", ...). Usually, objects will be created by calling the getRead method on an object of class SFFContainer.

Slots

name:

Object of class "character" representing the name of the read.

read:

Object of class "DNAString" containing the basecalled nucleotide sequence of the read.

flowgramFormat:

Object of class "numeric" representing the format used to encode each of the flowgram values for each read. Currently, only one flowgram format has been adopted and is coded by the value 1.

flowChars:

Object of class "character" containing the array of nucleotide bases ('A', 'C', 'G', 'T') that correspond to the nucleotides used for each flow of each read.

keySequence:

Object of class "character" representing the nucleotide bases of the key sequence used for these reads.

clipQualityLeft:

Object of class "numeric" representing the position of the first base after the clipping point for an attached quality sequence. If only a combined (quality+adapter) clipping position is computed it should be stored in clipQualityLeft. If no clipping value is computed the field is set to 0. The position values use 1-based indexing.

clipQualityRight:

Object of class "numeric" representing the position of the last base before the clipping point for an attached quality sequence. If only a combined (quality+adapter) clipping position is computed it should be stored in clipQualityRight. If no clipping value is computed the field is set to 0. The position values use 1-based indexing.

clipAdapterLeft:

Object of class "numeric" representing the position of the first base after the clipping point for an attached adapter sequence. If only a combined (quality+adapter) clipping position is computed it should be stored in clipQualityLeft. If no clipping value is computed the field is set to 0. The position values use 1-based indexing.

clipAdapterRight:

Object of class "numeric" representing the position of the last base before the clipping point for an attached adapter sequence. If only a combined (quality+adapter) clipping position is computed it should be stored in clipQualityRight. If no clipping value is computed the field is set to 0. The position values use 1-based indexing.

flowgram:

Object of class "numeric" containing the homopolymer stretch estimates for each flow.

flowIndexes:

Object of class "numeric" containing the flow positions for each base in the called sequence, i.e. for each base, the position in the flowgram whose estimate resulted in that base being called.

quality:

Object of class "BString" containing the quality scores for each of the bases in the sequence, where the values use the standard -log10 probability scale.
