bs3 killed and no output

[AdrianS85]

Hello!

Im trying to use BS-seeker3 for my experiment. Unfortunately, I am getting an error "Loading index from directory... Killed" and also no output is produced despite successful (?) alignment. I know that others have raised this issue, but I figured my case may be a bit different.

SOME RELEVANT INFORMATION:

• ps3_build seemed to work well, without any problems.
• My reads are paired, around 75 bp of length.
• I am working on Singularity-Ubuntu:18.04
• Seed size is 16.
• I have about 200GB RAM available
• Command that I used:

python ./bs3-align.py --snap-t 10 -1 ../read1.fq_trimmed.fq.gz -2 ../read2.fq_trimmed.fq.gz -g mm10ucsc.fa -f sam -o ./FullBS3test.sam -d reference_genome/

THE OUTPUT:

     BS-Seeker3 beta
