Mid-Winter release 2020
Release 3.4 of HiCExplorer comes with improvements in the documentation and smaller bug fixes:
- Fixing a bug in hicAdjustMatrix:
keep
option had a bug concerning the cutting before the end of a chromosome or the start position was not from the beginning of the chromosome - hicCompartmentPolarization was renamed to hicCompartmentalization and got some bug fixes:
- set an offset to remove diagonals to help with the artifact they may generate
- Removed the last quantile from the polarization calculation
- sum devides by count at the end of the loop and only affects the final output
- Extending the option on how the observed vs. Expected matrix is computed and adding the parameter
--ligation_factor
to achieve a rescale behaviour of the values as it is implemented in Homer. The same changes are applied tohicTransform
- Improved the documentation
- Adding an option in hicAverageRegions to select start, end, center or start_end as start index for up/downstream range.
- hicBuildMatrix: Removed default value of binSize to enable mutually exclusive group error if not one of them is set. Behaviour so far was that the binSize was taken.
- hicPlotSVL: adding xlegend to plot of SVL ratios to indicate the data points per boxplots are the chromosome ratios
- hicQuickQC: Removed binSize option of hicQuickQC because it does not matter for QC calculation and adding a sentence to recommend the usage of restriction enzyme and dangling end sequence. Fixing bug issue #464
- hicNormalize: Adding option in hicNormalize to remove values after the normalization if values are smaller than a given threshold
- Capture Hi-C modules: Change background model distribution assumption from negative binomial to continuous negative binomial by using Gamma functions as a replacement for the binomial coefficient.

- hicInfo: Implementing feature request #456. The length of chromosomes is now show in the information too
