Hi,

I'm trying to run graph_peak_caller on a ATAC-seq data which is aligned to a single test chromosome graph which was generated with the PGGB pipeline. After aligning the raw data to the graph using vg map, when I try to run graph_peak_caller callpeaks -g ch19.nobg -s alignments.json, I see the following:
