RNA sequencing (RNAseq) is a method used to study gene expression and transcriptomics. The bioinformatics analysis of RNAseq data involves several steps, including quality control, data preprocessing, alignment, quantification, differential gene expression analysis, and functional enrichment analysis.
If you are interested in RNAseq analysis, here at the Core Facility Bioinformatics, we are routinely analyzing data from:
We provide quality report of the sequencing reads and alignment. We perform differential expression analysis and provide results in form of tables and different graphics (volcano plot, PCA, Venn diagram, heatmap, …). We can also provide functional enrichment analysis (Gene Onthology, KEGG pathway,…)

DNA sequencing offers a comprehensive view of the genetic landscape, and DNA variant analysis is crucial for understanding genetic diversity and disease mechanisms. We can process Next-Generation Sequencing (NGS) libraries of various sizes, including Whole Genome Sequencing (WGS), Whole Exome Sequencing (WES), and specific gene panels.
Our DNA-sequenced data analysis process consists of primary quality control (QC), mapping, and post-mapping QC to confirm adequate coverage, followed by variant calling, variant annotation, variant filtering, and visualization.
Our services include:
We are committed to offering the most comprehensive and accurate DNA variant analysis. Our services can be adapted to a wide range of research needs. Whether you are studying common model organisms or non-model species, our skilled bioinformatics team is equipped to manage your DNA sequencing data with precision and expertise.

16S metagenomics analysis is widely used to study microorganisms in the gut microbiome and understand their evolutionary relationships. The bioinformatics analysis of NGS data involves crucial steps like demultiplexing, quality control, trimming, filtering, error rate estimation, sequence clustering, taxonomy assignment, phylogenetic tree construction, and visualization. These steps collectively enable an extensive exploration of the microbial community and its dynamics.
Here at the Core Facility Bioinformatics we provide customers with comprehensive quality reports of the sequencing reads. We also recognize the importance of sequence clustering in 16S metagenomics analysis. This process, often based on sequence similarity thresholds, allows the identification of operational taxonomic units (OTUs) or amplicon sequence variants (ASVs). OTUs or ASVs represent distinct microbial taxa or species present in the gut microbiome. Clustering facilitates the reduction of data complexity while retaining important taxonomic information, enabling downstream analyses such as taxonomic assignment and phylogenetic tree construction. For this purpose we include widely used tools such as DADA2 (using ASVs) and Mothur (using OTUs) into our analysis pipeline.
Metagenomics results are visualized using various techniques such as composition barplots, heatmaps, and phylogenetic trees. These visualizations should help researchers understand the structure and diversity of complex microbial communities. We are also able to perform differential abundance analysis.

Peak calling is a bioinformatics technique locating enriched regions of a genome usually conducted as secondary analysis after the alignment. This enrichment typically comes from experiments using chromatin profiling (i.e. CUT&RUN) or immunoprecipitation protocol to seek an interaction of proteins with DNA/RNA (i.e., ChIP-seq - protein/DNA interaction; CLIP-seq - protein/RNA interaction). The common analysis involves steps like peaks annotation, motif discovery, data visualization (e.g., FRiP, peak profiles), correction based on Irreproducible Discovery Rate (IDR), and Differential Peak Calling (DPC), but more steps can be provided tailored to the individual needs in forms of a Custom analysis.

CRISPR, standing for Clustered Regularly Interspaced Short Palindromic Repeats, is a groundbreaking tool that has transformed the field of genetic engineering with its high-precision genome editing capabilities.
At our Bioinformatics Core Facility, we provide exhaustive analysis services for Genome-wide CRISPR-Cas9 knockout screen experiments. The procedure for CRISPR bioinformatics analysis is a multistep process that commences with quality control and data preprocessing, and progresses to the crucial stage of alignment and counting of sgRNAs, which essentially quantifies the proliferation of knockout gene cells.
To optimize the precision of the alignment and counting of reads from various single guide RNAs (sgRNAs), we integrate the use of the MAGeCK tool with our own custom-developed in-house algorithm. This unique pairing of techniques augments the sensitivity of the alignment process, thereby assuring superior quality in our data analysis.
As an additional part of our service, we conduct an analysis of differential cell proliferation per knockout gene between different conditions. The outcome of this analysis is presented in the form of comprehensive tables and a variety of graphical visualizations such as volcano plots, box plots, and heatmaps, among others. If required, we can also perform gene set enrichment analysis on the differentially proliferated knockout gene cells, thereby providing a more holistic view of the results.
Example: Genome-wide CRISPR-Cas9 knockout screen experiments with human cells infected with GeCKO library treated by viral infection. Samples were extracted 24 and 48 hours after the treatment with one untreated control. Three biological replicates were used per condition.

Reference assembly is a bioinformatics technique merging the relatively short sequencing reads into the original sequence. Typically, the short reads come from genomic DNA or gene transcripts (RNA). The length of reads can vary between tens and hundred thousands of bases. We provide De-novo as well as Reference-guided assembly.
The common analysis involves steps like the raw reads quality control, quality and/or adapter trimming, correction of sequencing errors, alignment to the reference (only for reference-guided assembly), sequence reconstruction performed by various assemblers with different settings, joining of assemblies based on consensus sequence or gene prediction, various quality control steps, and automatic annotation using several tools and databases (e.g., UniProt/SwissProt, NCBI’s nucleotide, RefSeq).
