E of reads might be aligned to reference by identity varied. The valid contigs price equals the amount of the contigs which successfully aligned to references dividing the total reads quantity in the database.3. Outcome and Discussion3.1. Assembled Reads. 16 function gene samples have been sequenced in one run and two fastq files (each file includes 589573 reads) were output. The usage on the methods referred above to assembled reads and 390992 pairs of reads had been effectively assembled. The assembled reads price was about66.32 . The typical length of assembled reads was 155.ten, which illustrated that when two reads assembled nearly 50 bp locus might be overlapped. More than 98.56 assembled reads were assembled by reverse complementary reads; meanwhile PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21339327 the 1.5 assembled reads from others might have pretty low high-quality. To get accurate outcome, raw information were reprocessed (Figure 1), and only assembled reads with both forward and reverse complementary reads have been chosen for accurate sequence. As we checked the sequence data, only 1520 bp of original reads in the finish have been of low excellent. Hence the low excellent segment on the two reads is going to be aligned for the other reads (Figure 2). If there’s any diverse code in the alignment locus, that locus might be set as “N” and when we align reads to references sequence, “N” is not going to be calculated. Hence, the problem of low good quality segment in the reads will probably be solved. In blast outcome on the Rapastinel nonassembled reads database, most contigs are longer than 80 bp; meanwhile when blasting in assembled reads database, there were lots of quick contigs (extra or less than 20 bp) aligned to references. We use standalone BLAST tool to blast function genes in regional database. To examine the sequence good quality on the assembled and nonassembled reads, we made two nearby databases. 1 database consists of assembled reads and the other consists of nonassembled reads. When blasting within the assembled reads database, 321919 contigs have successfully aligned towards the function genes when the identity threshold was set as 85 identities plus the number of contigs changed to 249076 by the threshold 90 identities. Because of blasting in nonassembled database, 314977 contigs from 397162 recorders have been aligned towards the same query sequence (Table two). Comparing both assembled and nonassembled valid reads by different blast thresholds, assembled sequence performed high mapping rate (Figure 3).
