Augmentation failed on one chromosome, but succesfull on other chromosomes

[mas-agis]

-->

1. What were you trying to do?
I tried to call vcf for each splitted chromosome after aligning short reads against the variation graph.

2. What did you want to happen?
Vcfs for all chromosome should be called separately.

3. What actually happened?
One chromosome reported error on the agumentation step while vcfs for other chromosomes were successfully called.

4. If you got a line like Stack trace path: /somewhere/on/your/computer/stacktrace.txt, please copy-paste the contents of that file here:

5. What data and command can the vg dev team use to make the problem happen?
These are the subsequent steps I executed. For this chr17, it failed on the augmentation step.

# augment the graph, filtering out mappings and bases with quality < 5, and breakpoints with coverage < 4
# the -s option is crucial
echo "Starting augmentation";
vg augment chunk_"$i".pg  chunk_"$i".gam -s -m 4 -q 5 -Q 5 -A chunk_"$i"_aug.gam > chunk_"$i"_aug.pg;

# compute the snarls
echo "Computing snarls";
vg snarls chunk_"$i"_aug.pg > chunk_"$i"_aug.snarls;

# compute the support
echo "Computing support";
vg pack -x chunk_"$i"_aug.pg -g chunk_"$i"_aug.gam -o chunk_"$i"_aug.pack;

# call variants on the component
echo "Calling variants";
vg call chunk_"$i"_aug.pg -r chunk_"$i"_aug.snarls -k chunk_"$i"_aug.pack -s "$indiv" > chr_"$i".vcf ;

6. What does running vg version say?

vg version v1.52.0 "Bozen"
Compiled with g++ (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 on Linux
Linked against libstd++ 20230528
Built by jeizenga@emerald

Looks like maybe the gam file is nonexistent or corrupted. You can verify by doing something like

vg validate chunk_"$i".pg  -a chunk_"$i".gam

[mas-agis]

It reports similar messages. How to chunk the gam only for chr 17? I chunk the vg and gam together before.

the pg is valid

vg validate chunk_17.pg
graph: valid

[glennhickey]

I think you have to hcunk the vg and gam together (depsite what the options may lead you to believe). You can just do that and only use the gam output.
