Error in pipe output to samblaster from bwa-mem2

Hi,

I am trying to upgrade my command from bwa to bwa-mem2. This command usually works.

bwa mem -M -R “@RGtID:idtSM:sampletLB:lib” human_g1k_v37.fasta
sample.1.fq sample.2.fq | samblaster -M –excludeDups –addMateTags
–maxSplitCount 2 –minNonOverlap 20 | samtools view -S -b – > sample.bam

Once I start using bwa-mem2, the piping breaks.

bwa-mem2 mem -M -R “@RGtID:idtSM:sampletLB:lib” human_g1k_v37.fasta
sample.1.fq sample.2.fq | samblaster -M –excludeDups –addMateTags
–maxSplitCount 2 –minNonOverlap 20 | samtools view -S -b – > sample.bam

Do you have any idea to run samblaster from bwa-mem2 ?? Thanks !
