Hi, I get a core dump when Mira attempts to write contigs (see below for manifest file inputs and where the dump takes place) I am running on a virtual machine that has over 20GB RAM and 4 threads allocated. Any idea how to remedy this? The only log file I could find was in the temp folder, named "miralog.noqualities", and was empty. Many thanks in advance Manifest file: project = cDNAvsReference job = mapping,est,accurate parameters = -GE:number_of_threads=4 \ COMMON_SETTINGS -SB:abnc=yes \ -OUT:ota=on \ 454_SETTINGS -CL:qc=no:cpat=1 \ -AS::enforce_presence_of_qualities=no \ readgroup=cDNA data=cDNA_in.454.fasta technology=454 readgroup=backbone data= backbone_in.fna technology=454 as_reference Error: " Sorting confirmed overlaps (this may take a while) ... done.
