SFFContainer-class: Class '"SFFContainer"'

Description Objects from the Class Slots Methods Author(s) See Also Examples

Description

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

Objects from the Class

Objects can be created by calls of the form new("SFFContainer", ...). Usually, objects will be created by calling the readSFF method on a file in SFF format.

Slots

name:

Object of class "character" containing the name of the file this SFFContainer was created from.

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 for each read. 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 for each read. 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 for each read. 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 for each read. 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.

flowgrams:

Object of class "list" containing the homopolymer stretch estimates for each flow using one list item for each read.

flowIndexes:

Object of class "list" 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. Each read has its own list item.

reads:

Object of class "QualityScaledDNAStringSet" containing the basecalled nucleotide sequences of each read together with the quality scores for each of the bases in the sequence using the standard -log10 probability scale.
