hicPlotMatrix --bigwig not at correct position

[GinaRe]

When I use hicPlotMatrix --bigwig PC1.bw without --clearMaskedBins to plot a Hi-C matrix and its A/B compartment track, the position of the bw track is not correct. This only happens when the start of a chromosome is removed (using hicAdjustMatrix). The bw track in the following plot should start at the start of the matrix.

Implemented with version 3.5.

I have tested version 3.5. The same problem persists. Here are the examples:

1. hicPlotMatrix -m Dmel_m50_pearsonMatrix.h5 -o Dmel_m50_pearsonMatrix_v11.pdf --bigwig Dmel_A840_Rep1_Rep2_merge_m50_corrected_adjusted_PCA.bw --chromosomeOrder 2R
2. hicPlotMatrix -m Dmel_m50_pearsonMatrix.h5 -o Dmel_m50_pearsonMatrix_v12.pdf --bigwig Dmel_A840_Rep1_Rep2_merge_m50_corrected_adjusted_PCA.bw --chromosomeOrder 2R --clearMaskedBins

The second version using --clearMaskedBins shows the correct position of the bw track. I have removed 0-7Mb from the matrix using hicAdjustMatrix.

I have tested this, and I generated another error.
