Common Signal Shift

Distance between predicted and observed signal at the allele locus. [RBI]

Reference Signal Shift

Distance between predicted and observed signal in the reference allele. [REFB]

Variant Signal Shift

Distance between predicted and observed signal in the variant allele. [VARB]

Relative Read Quality

Phred-scaled mean log-likelihood difference between the prediction under reference and under the variant hypothesis. [MLLD]

HP Length

Homopolymer length.

Context Error +

Probability of sequence-specific error on the forward strand (reported only for deletion variants).

Context Error -

Probability of sequence-specific error on the reverse strand (reported only for deletion variants).

Context Strand Bias

Basespace strand bias (reported only for deletion variants).
