Hello again. I've generated a gam (for many samples) using vg: variation graph tool, version v1.27.1 "Deliceto"

./vg map -t 16 -s $xg -g $gcsa -i -f "$R1" -f "$R2" > "$vg"_CP"$numbers"_2.gam

This command works and everything seems to be writing correctly to the .gam, but when I try to generate a vcf from the augmented graph it's completely blank. Here are the vg files' and augmented files' info (is the increase in size for augmented usual? Is that contributing to this issue, if so how much should I try to run this with?

bash-4.2$ ./vg pack -x sxab/mod_F_KS_P_RNA_scaffold_11_gfa.xg -g mod_F_KS_P_RNA_scaffold_11_gfa_CP41.gam -Q 5 -o mod_F_KS_P_RNA_scaffold_11_gfa_CP41.pack

bash-4.2$ ./vg call sxab/mod_F_KS_P_RNA_scaffold_11_gfa.xg -k mod_F_KS_P_RNA_scaffold_11_gfa_CP41.pack

bash-4.2$ ./vg call sxab/mod_F_KS_P_RNA_scaffold_11_gfa.xg -k mod_F_KS_P_RNA_scaffold_11_gfa_CP41.pack -a >> Reference_F_KS_P_RNA_scaffold_11_gfa.vcf

Also, is there a way to generate a vcf with invariant regions <.> in the alt column?
