Furthermore, the attenuation correction was incorporated in the iterative reconstruction process, which in some reconstruction algorithms may cause problems since they require a new system matrix for each subject to be imaged.
Generally Markov models assume transitions from one health state to the next occur at the end of the cycle, however in reality this transition can occur at any point during the cycle, therefore a half-cycle correction was incorporated.
Several unique correction procedures, such as multi-read correction, bias correction and effective length correction, are incorporated only in Cufflinks2 and Cuffdiff2 [ 33]. edgeR, DESeq2 and Cuffdiff2 calculate their p values by the generalized linear model (GLM) likelihood ratio test [ 32], GLM Wald test [ 31] and t-test [ 12], respectively.
Random and scatter corrections are incorporated into the iterative algorithm, with scatter correction performed using a fully 3D approach that considers both the axial and trans-axial scatter components.
A power factor correction function is incorporated in the shunt active filter to achieve a power factor that is near to unity.
To remove systematic errors in the model simulation originating from structural and parametric errors, a parsimonious bias correction procedure is incorporated into the observation equation.
An algorithm that is able to compensate for such conflicting updates by a local correction strategy, called local compensation (LC), is incorporated into SDCC.
