Fail to sterilize graph (Segmentation fault (core dumped))

[hqyone]

Hi Sir
I compiled the HLA-LA on my Ubuntu 20 EC2 with 16 core and 128G ram.
It passed the test using the command ../bin/HLA-LA --action testBinary

But got error during prepareGraph PRG_MHC_GRCh38_withIMGT. Following is the error message:
[ Thu Jan 5 04:30:34 2023 ] Read graph from ../graphs/PRG_MHC_GRCh38_withIMGT
30200000/30207167[E]

[ Thu Jan 5 04:37:05 2023 ] done
[ Thu Jan 5 04:38:04 2023 ] Now serialize (pre-gap-pathindexed) graph to ../graphs/PRG_MHC_GRCh38_withIMGT/serializedGRAPH_preGapPathIndex
Segmentation fault (core dumped)

I'm sure I have enough hard driver space and RAM.
bwa = 0.7.17-r1188
samtools=1.13
picard: installed by apt-get install picard-tools

Could you help me to fix the issue?

Thank you so much

Hi @hqyone,

This is very difficult to debug remotely. Could you try running on another machine?

Best wishes
