No dots/lines in the coverage by chromosome view (CBCV)

[Bin-Guan]

Hello, We run version 1.1 on a bam and all steps completed without errors. However, the coverage by chromosome view in the QC_report.pdf showed 24 lines of "## Warning: NAs introduced by coercion" followed by a grid of 1 to 22 without dots or lines. What could be the problem?

Tested using the supplied bam file NA12878.grch38.subsampled.bam, it showed the same problem. The text file in SVs\qc\chromView\ only had chromosome numbers but no other information: chr1 TAB ... chrXX TAB chrY0 TAB chrM TAB

Thank you.
