Hi Bastien, I have some questions about statistics after assembly. Here is the information from “info_assembly.txt”. Read assembled: 86373 Singlets: 3445 Number of contigs: 7012 The number of reads in the “info_contigreadlist.txt” is 84741. The number of reads in the “info_debrislist.txt” is 15145 Here is the statistics from result fasta file. Unigenes with “_c” tag: 6524 Unigenes with “_lrc” tag: 488 Unigenes with “_s” tag: 1813 The following are my questions. 1. What is difference between “read assembled” and reads which are listed in the “contigreadlist.txt” (86373 != 84741)? 2. It seems that you treat part of debris as singlets (3445 != 15145), and you didn’t put all of singlets into result fasta file (3445 != 1813). Could you explain more about this? I used command line as following. mira -project=CBreton_Region_1_MID22 -fasta -job=denovo,est,normal,454 -notraceinfo -OUT:sssip=yes:ora=yes -AS:ugpf=no:sep=yes:bdq=20 -AL:ms=20:mrs=85:egp=yes -CL:pvlc=no:pvcmla=25:cpat=on:qc=no:qcmq=16:qcwl=20 -ED:ace=yes -SK:not=2:pr=50 Thanks a lot in advance and Best regards, --Dong
