You can extract paths as a FASTA using vg paths --extract-fasta
. I think the interface requires a GBWT as input, so you may need to pull out the GBWT from your GBZ using vg gbwt
.

Dear developer:
We encountered some problems in vg index, showing insufficient memory, but our running memory is 1TB, I would like to ask whether our code and thinking are correct, and how should we solve this problem?
vg mod -X 256 test.full.vg > test.full.mod.vg
vg index -x test.full.xg -g test.full.gcsa -k 16 -t 8 test.full.mod.vg
error:
InputGraph::InputGraph(): Memory use of input kmers (1149.82 GB) exceeds memory limit (1024 GB)
vg gbwt -g test.full.gbwt -t 8 -x test.full.xg test.full.vg

Is there a reason you are doing a manual indexing pipeline instead of using vg autoindex
? For most users, vg autoindex
is more robust to issues like this.
It's also unclear to me which mapping tool you're planning to use. The GCSA2 index is used by vg map
, but the GBWT usually is not. The GBWT is typically used in vg giraffe
. This is another reason to use vg autoindex
: it can determine exactly which indexes you need based on the mapping tool you want to use.
