Is there any existing tool which can calculate how many reads are mapped in .gam file which is generated by command: vg map

for example the .gam file is "graph.read.gam"

You can get some basic statistics about the GAM file with vg stats -a alignments.gam [graph-name]. The graph file is optional, but if you include it, vg stats will compute some extra statistics.
