Segmentation fault when checking the environment with testing samples

[Xgiintghhuabi302]

Dear ChaissonLab,
I am trying to check my environment by running on the testing samples with command:
snakemake -p -s ../pipeline/GoodPanGenomeGraph.snakefile -j 4 --rerun-incomplete --output-wait 5
and I encountered some problems in this line:
/home/txren/my_path/danbing_tk/danbing-tk/bin/ktools serialize /home/txren/my_path/danbing_tk/danbing-tk/test/output/pan
with the err:
reading kmers from /home/txren/my_path/danbing_tk/danbing-tk/test/output/pan.graph.kmers /usr/bin/bash: line 4: 1863431 Segmentation fault (core dumped) /home/txren/my_path/danbing_tk/danbing-tk/bin/ktools serialize /home/txren/my_path/danbing_tk/danbing-tk/test/output/pan
Could you help me with this issue?

Hi, I also encountered the same problem. Have you solved it?

Command

@jingydz i haven't fixed the issue, but i note that the test was built on v1.0, so i roll back to the v1.0 and the fault didn't appear.
Hope this helps you.

Hi @Xgiintghhuabi302 and @jingydz,

Thanks for reaching out. I've just fixed the bug in the latest commit 4b64113. The reason is that genPanKmers did not write kmer names but ktools serialize require kmer names. Let me know if the issue exists or if you run into other issues.

Cheers,
-Tony
