Abnormal size of *.0.hic

Hi, I run 3d-dna with a 4.17G genome, but I got a abnormal size of *.0.hic, The log file is as follows：

Thank you!

Hello, I encountered the same error as you, did you solve it?

[linshengnan09]

I have solved it with increasing -Xmx memory of juicebox_tools.sh script.

Hi, @linshengnan09
When I deal with a 3.8G genome with run-asm-pipeline.sh. There is an issue like '.Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded'. What would be a suitable value should I set for the parameter -Xmx in juicertool.sh to resolve this issue and will not cause my server to crash. Here is the memory status of my server (Linux):  Thanks in advance!

Hi, @zhangna123-ux , I increased the default memory by 10 times, i.e. set it to: -Xms491520m. I think you can try setting it to 5 times. If that doesn’t work, increase it a little more.

Hi, @linshengnan09 Thank you very much for your prompt reply. I will go and try your suggestion right away.
