bwa mem -a and -t options are incompatible?
Hi,
When I wanted to run bwa mem
with all alignment options -a
and parallelization using -t
, I find that the output only contains the best alignments. Even if I try to run it as a slurm job using separate nodes for each sample without -t
, I still get only the best alignments. Both ways of parallelization failed to provide all alignments. Any help is much appreciated.
example code: bwa mem -a contigs.fasta -p 0_reads.fq -t 24 > 0_sample.sam
I notice that setting the -K
option (bases to be processed in each batch) to a large value ensures reproducibility. However, will it solve the specified problem for the -a
option as well?
Thank you.
Best, Yazhini
