Footer position missing in .hic file?

[matthias...@inra.fr]

Dear everyone,

I am reading a inter.hic file.

Here are the first lines of the file:

$ xxd inter.hic | head -1
00000000: 4849 4300 0800 0000 0000 0000 0000 0000  HIC.............

As you see, the .hic is version 8, but the footer position is not given.

The inter.txt says:

Experiment description: Sample name HiC_sample; Juicer version 2.0; BWA 0.7.17-r1188; 6 threads; openjdk version "11.0.16" 2022-07-19; Juicer Tools Version 1.9.9; /XXX/scripts/juicer.sh -d /XXX/ -z /XXX/references/mygenome.fa -p /XXX/references/mygenome.size -y /XXX/references/mygenome_mynuc.txt -D /XXX/ -t 6 -g mygenome 

Juicer worked without problem.

Is there any reason why the footer position was removed/not added?

Thanks!

Matthias.

Hi Matthias,

How do you know that the footer position was removed/not added?
