Abstract Motivation: Multiple sequence alignments (MSAs) are at the heart of bioinformatics analysis. Recently, a number multiple protein alignment benchmarks (i.e. BAliBASE, OXBench, PREFAB and SMART) have been released to evaluate new existing MSA applications. These databases well received by researchers help quantitatively programs on sequences. Unfortunately, analogous DNA not available, making evaluation difficult for Results: This work presents first known that (1) comprised...

Introduction Addressing the problem of suicidal thoughts and behavior (STB) in adolescents requires understanding associated risk factors. While previous research has identified individual protective factors with many adolescent social morbidities, modern machine learning approaches can help identify that interact (group) to provide predictive power for STB.

The computing community has long faced the problem of scientifically comparing different computers and algorithms. When architectures, methods, precision, or storage capacity are very it is difficult misleading to compare speeds using ratio execution times. We present a practical fair approach that provides mathematically sound comparison computational performance even when algorithm, computer, precision changed. HINT (Hierarchical INTegration) removes need for pseudo-work measures such as...

Genome assemblers to date have predominantly targeted haploid reference reconstruction from homozygous data. When applied diploid genome assembly, these perform poorly, owing the violation of assumptions during both contigging and scaffolding phases. Effective tools overcome problems are in growing demand. Increasing parameter stringency is an effective solution obtaining haplotype-specific contigs; however, algorithms for such contigs lacking.We present a stand-alone algorithm,...

Error correction is an important step in increasing the quality of next-generation sequencing data for downstream analysis and use. Polymorphic datasets are a challenge many bioinformatic software packages that designed or assume homozygosity input dataset. This assumption ignores true genomic composition organisms diploid polyploid.

Long branch attraction (LBA) is a problem that afflicts both the parsimony and maximum likelihood phylogenetic analysis techniques. Research has shown particularly vulnerable to inferring wrong tree in Felsenstein topologies. The long extraction method procedure detect data set suffering from this so Maximum Likelihood could be used instead of Parsimony. been well cited by many authors their but no strong validation performed as its accuracy.

The contig orientation problem, which we formally define as the MAX-DIR has at times been addressed cursorily and using various heuristics. In setting forth a linear-time reduction from MAX-CUT problem to prove latter is NP-complete. We compare relative performance of novel greedy approach with several other heuristic solutions.Our results suggest that our algorithm not only works well but also outperforms algorithms due nature scaffold graphs.

Before implementing scheduling policies (i.e. job prioritization) on a system, it is imperative that their effects performance be understood. Changing without this knowledge may result in issues such as starvation, increased queue time, and decreased system utilization. This paper proposes means of reproducibly accurately determining the true impact changes policy, resource configuration, workload distribution. The proposed solution, Maui Scheduler possesses an advanced, easy-to-use,...
