[…] fig. ). these results indicate that raw interaction counts in cancer hi-c data are biased by cnvs and should be corrected to obtain per-copy chromosome interaction map. we compared the ice and hicnorm methods for normalizing the interaction matrix. ice can better correct the cnv bias than hicnorm (fig.  and supplementary fig. ), so we used it to obtain normalized hi-c matrices […]

[…] source of these non-proximity factors. instead, it operates on the principle that all genomic regions should be equally visible and partake in an equal number of interactions. the second technique, hicnorm, attempts to remove the impact of three non-proximity factors known to affect observed interactions, fragend frequency, gc content and mappability. the iteratively-corrected normalized […]

[…] read count bias, including a non-parametric probabilistic approach due to yaffe and tanay and iterative correction and eigenvalue decomposition (ice), which approximates this method. more recently, hicnorm was introduced to learn these biases statistically with poisson regression, using gc content and other features as covariates in a generalized linear model (glm) for interaction bin counts.

[…] analytical pipelines have been developed that employ two main normalisation tactics. one approach models the effects of each bias separately and has been taken by the hicpipe (yaffe and tanay ) and hicnorm (hu et al. ) pipelines, applied to hi-c libraries. whilst it has not been used in the analysis of capture hi-c libraries, these models could be extended with the inclusion of an extra […]

[…] regions may control distant genes through long-range interactions. we used chromosome conformation capture (hi-c) data to test this hypothesis. using two independent normalization methods, hicnorm and yaffe to identify consensus interacting partners in k562 and gm06990 cell lines, we identified the chromatin region containing rs1635852 and other diagram-snps reaching genome-wide […]
