panacus hsitgrowth returns NaN for first line of output with 0.

Hello, I have constructed a pangenome using minigraph-cactus, and was trying to use panacus to get the histogram values.

I have about 849 assemblies used for my pangenome.
I used the following command

haplo=ab.paths.haplotypes.txt
RUST_LOG=info panacus histgrowth -t8 -l 1,2,1,1,1 -q 0,0,1,0.5,0.1 -S -a -s ${haplo} ab.gfa > ab.histgrowth.node.tsv

and this is part of the truncated results:

panacus hist growth growth growth growth growth
count node node node node node node
coverage 1 2 1 1 1
quorum 0 0 1 0.5 0.1
0 18892 NaN NaN NaN NaN NaN
1 719272 913762 912915 913762 913762 913762
2 375826 1069307 1067612 758218 1069307 1069307
3 227182 1162781 1160240 696148 882358 1162781
4 156027 1235106 1231717 655229 945808 1235106
( ... )

I think there may be an issue with having too many paths?
Thank you in advance.

No, this line is not an issue and is in fact expected. The line starting with 0 tells you that there are 18892 nodes with a coverage of 0. If you have added 0 paths to the graph there is no graph and thus the concept of growth does not make sense yet. That is why NaN is inserted as a placeholder.
