Segmentation fault: 11 on modbam files (ONT)

[Machadum]

Hi again

I am a newbie. I have modbam files from ONT that I try to call SVs on but I have Segmentation fault: 11 error. Do you have an idea of what it could be? Also it does not indicate the avg DEL/INS ratios to start with, which worries me a bit.

sniffles --mapped_reads /Volumes/Rita/Pilot/output/SL7-1_bam_pass_merged_sorted.bam --vcf SL7-1.vcf --tmp_file /Volumes/Janet/sniffles/ --threads 8 --cluster  --genotype
Estimating parameter...
	Max dist between aln events: 53
	Max diff in window: 50
	Min score ratio: 2
	Avg DEL ratio: nan
	Avg INS ratio: nan

	Writing SV calls
Segmentation fault: 11

Many thanks for your help

Hello, @Machadum
which version of sniffles are you using?
It seems that you are using sniffles1
We recommend you to switch to sniffles2

Hi thank you for your quick answer. The switch to sniffles2 unfortunately does not work:

conda update sniffles=2.3

Retrieving notices: ...working... done

CondaError: Invalid spec for 'conda update': sniffles=2.3
Use 'conda install' instead.

conda install sniffles=2.3
