ESBL detection via multiplex pyrosequencing

This new application was developed using an improved version of three previously published algorithms including AdvISER-PYRO for analyzing low and complex signals resulting from samples including several mycobacteria, AdvISER-M-PYRO for analyzing overlapping pyro-signals generated from multiplex reactions conducted on mono-allelic genes in bacteria, and AdvISER-MH-PYRO for analyzing overlapping pyro-signals generated from multiplex reactions to genotype bi-allelic human SNP.
While the initial version of AdvISER-M-PYRO analyzed multiplex pyrosequencing signals by selecting a single and unique sequence for each genomic region, this new version enables the analysis of multiplex pyrosequencing signals generated from samples including two distinct sequences (i.e., plasmid and chromosomal) for each genomic region.

 

AdvISER-PYRO

Interpreting a pyrosequencing signal appears highly challenging when signal intensities are low (unitary peak heights smaller than 5) or when complex signals are produced by more than one target amplicon in the sample. AdvISERPYRO is an efficient algorithm that can reliably be used to identify amplicons in pyrosequencing signals generated by Single Amplicon Samples (SAS) and Multiple Amplicon Samples (MAS). AdvISERPYRO is based on a sparse regression model and deciphers each amplicon-specific signal that contributes to the resulting global signal.

 

AdvISER-M-PYRO

AdvISER-M-PYRO is an efficient algorithm that can reliably be used to translate the global multiplex pyrosequencing signal in sequences corresponding to each genomic region.
The new SENATOR method was developed to select the nucleotide dispensation order to be used all along the multiplex pyrosequencing experiment.

 

AdvISER-MH-PYRO

AdvISER-MH-PYRO is an extension of the AdvISER-M-PYRO algorithm that integrates a new feature allowing bi-allelic SNP genotyping. AdvISER-MH-PYRO can be applied in a broad range of clinical and/or research applications relying on Multilocus Genetic Risk Score computation, hence requiring multi-SNP pyrosequencing for each patient. AdvISER-MH-PYRO package also includes 2 dictionaries for quadruplex and quintuplex assays to genotype a set of prostate cancer-related SNPs (n=9).

 

Saturation R

The main function of the saturation R package is the cms2a function. This function can be used to correct the microarray saturated spots obtained at high PMT voltage by using the corresponding spots acquired at lower PMT voltage. The cms2a algorithm is based on a two-way ANOVA model and on a maximum likelihood estimation of the scanner optical bias.
