Abstract


As high-throughput sequencing applications continue to evolve, the rapid growth in quantity and variety of sequence-based data calls for the development of new software libraries and tools for data analysis and visualization. Often, effective use of these tools requires computational skills beyond those of the average researcher.

To lower this computational barrier, we have created a dynamic web-based platform, NASQAR. It provides an intuitive interface that allows users to easily and efficiently explore their data in an interactive way using popular tools for a variety of applications, including Transcriptome Data Preprocessing, RNAseq Analysis (including Single-cell RNAseq), Metagenomics, and Gene Enrichment

Citation

Lastly, if you use any of the apps on our portal as part of a publication, please remember to add the appropriate NASQAR citation, as follows:

NASQAR: A web-based platform for High-throughput sequencing data analysis and visualization
