bismark bowtie2 #645
Comments
Hmm this is tricky to debug, but my guess would be that you are running out of memory. On what kind of system are you running this on? I would definitely suggest you drop the parameter
|
Thank you for your response. I am using Linux version 3.10.0-862.el7.x86_64 ***@***.***) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC)) #1 SMP Fri Apr 20 16:44:24 UTC 2018. I am running the job on a slurm cluster using sbatch. However, when I tried aligning with "--hisat2 -p 10", the alignment rates ranged from 68% to 70%. I will now try removing the "-p 10" option and see if I can successfully run with Bowtie2. Thank you again for your response.

Hmm this is tricky to debug, but my guess would be that you are running out of memory. On what kind of system are you running this on? I would definitely suggest you drop the parameter -p 10, and see if that works?

Just for your information, there is still an open issue (#638) describing a memory leak specifically with Bowtie 2 v2.5.2. Is there a chance you ran into the same issue? |

The code is as follows:
bismark --bowtie2 -p 10 --genome .. /st_8_bow2_idx/ --basename Stem_WGBS_rep1 -o 2.align/ -1 .. /1.cleandata/Stem_WGBS_rep1_R1_clean.fq.gz -2 .. /1.cleandata/Stem_WGBS_rep1_R2_clean.fq.gz 1>2.align/Stem_WGBS_rep1.log 2>&1
How to solve the error as follows:
(ERR): bowtie2-align died with signal 9 (KILL)
Use of uninitialized value $alignment_score_2 in concatenation (.) or string at /home/yanghj/my_data/software/Bismark/Bismark/bismark line 3378, line 19786920.
