LRSIM crashes and reports "not defined chr1_182578874_182579@chr1"

[morispi]

Hi,

I am attempting to run LRSIM on a human chr1, but I'm encountering the aforementioned error.

Here is the command I'm using: perl ../simulateLinkedReads.pl -r ./Chr1.fasta -p SapiensChr1 -c fragmentSizesList -x 30 -f 50 -t 500 -m 10 -0 0 -o

And here is LRSIM output:

Command exited with non-zero status 25

It does not seem to be a memory issue, since it only uses 4 GB.

Moreover, when when I try to slightly modify the parameters (for instance setting -x 10 or -n to skip the variants simulation), the error seems to change randomly.
I once had Cannot find correct chromosome and position in @chr1_82788009_82787815_1_0_0_0_0:0:0_0:0:0_0/2, and once had Cannot find correct chromosome and position in IFIHIGIIFIGFEBFCHD@DEECDCBEDECCB@BCBABBFBCABCA@DC@BAAAB@?A@?@?>?B?C@?@B<>??:??@@>>?>A@==A@@@@<@A@@>>B=@>?>C>?>?=>??;;>>?=?>==?=>;?;;==<and other variations.

I'm having a hard time understanding what is going on here.
I already managed to run LRSIM correctly on smaller datasets and never encountered this issue.

Do you have any suggestions?

Thanks,
Pierre

For information, LRSIM does work well on a subset of human chr1, if that might help.
Still not sure what's causing the issue on the full chromosome though.
