[…] umina HiSeq2500 sequencer (Illumina). A total of 4.3 Gb and 4.6 Gb of 150-bp paired-end fragments were generated for IMS0493 and CBS1483 respectively. Chromosome copy numbers were estimated using the Magnolya software tool (Nijkamp et al., ; Oud et al., ). For visualization purposes, assembled contigs and their copy number were mapped on an illumina reads based-assembly of S. pastorianus CBS1483 ( […]

[…] esults. SNP/indel locations called from reads of the assembly strain were considered as false-positive and removed. The remaining hits were manually reviewed with a genome browser.With cn.mops [] and Magnolya [] two different approaches to detect potential copy number variations (CNVs) were applied. cn.mops was chosen due to its applicability for haploid organisms. Magnolya, which uses co-assembli […]

Implications of evolutionary engineering for growth and recombinant protein production in methanol based growth media in the yeast Pichia pastoris

2017
Microb Cell Fact

[…] stus [] was used for gene prediction. Annotation was performed by matching predicted genes against the CBS 7435 reference strain using blast. Variant-calling was performed using kSNP3 [] and GATK []; Magnolya [] and cn.mops [] were applied in order to test for potential CNVs in the evolved strains. Co-assembly for Magnolya was performed with velvet []. Alignment files were manually reviewed using […]

A new laboratory evolution approach to select for constitutive acetic acid tolerance in Saccharomyces cerevisiae and identification of causal mutations

2016

[…] g to the CEN.PK113-7D sequence annotation []. Raw sequencing data have been deposited as short-read archives (Bioproject: PRJNA313456/SRP070976, individual accession numbers in Additional file ). The Magnolya algorithm was used to analyse copy number variation using Newbler (454 Life Sciences, Branford, CT) for co-assembly of sequence reads of CEN.PK113-7D and the sample of interest []. Integer co […]

When there was no prior knowledge of the ploidy, the gamma setting was set to none. Magnolya uses a Poisson mixture model to estimate the integer copy number of an assembled conti […]
