Dear Bastien, I am trying to map 4,5 million illumina reads onto 126215 reads derived from a de novo 454 assembly. I am consistently getting boost::thread_resource_error. Most illumina reads are 61 bases long (adapter clipping, quality trimming and duplicate removal were performed by external tools). It is probably not a memory problem. miramem estimates the memory needs at about 10 Gb, and I am running the job on a node with 60 Gb RAM. Here is my script to call MIRA: --project=first_Norm1_vs_combined454 --job=mapping,est,accurate,solexa -SB:lb=yes:sbuip=1:bft=fasta COMMON_SETTINGS -GE:not=1 -SK:mchr=40 96 SOLEXA_SETTINGS -CO:msr=yes Could you please tell what is wrong?
