Memory error when using metasv

[daxian248]

I'm using metasv to merge the output of pindel, cnvnator and breakdancer. But I get the error "OSError: [Errno 12] Cannot allocate memory". I want to know if the metasv read all the bam file into memory when merge the SVs. Here is my command: run_metasv.py --reference /public/home/ylma/genome/Sus_scrofa/Sus_scrofa.Sscrofa10.2.dna.toplevel.fa
