The track operation Depth Graph (All) is used to summarize the depth of reads. It does not include soft-clipped parts of the read.
Add Depth Graph (Soft-clip) as a track operation for bam/sam. This would create a depth graph for just soft-clip parts of reads.
This should be possible to do by copying how Depth Graph (All) functions, but using only syms of instance BamSoftChildSingletonSeqSym.
