Visualization of running alignments of reads and contigs facilitates easy analysis and is useful in presenting assembly results. Several tools such as Artemis, BLAST Web, Circos, and so on, exist. A new tool called Alvis is developed for easy alignment and visualization of contigs and reads . It can also be used for chimera detection.
Alvis is a user-friendly command-line tool capable of generating visuals of common alignment tasks. It can generate four different kinds of diagrams and accepts the input in different formats including BLAST tabular, PAF format from minimap2, SAM files, PSL file, and MUMmer’s .coords and .tiling files. Users can also filter the alignments. Alvis highlights the potential chimeric contigs or reads in the output.
The visualization output of Alvis includes:
- alignment diagram,
- contig alignment diagram,
- coverage map diagram, and
- genome coverage diagram.
Alvis is written in Java with a simple command-line interface. It is platform-independent unless it consists of a Java Runtime Environment. Alvis is freely downloadable from Github.

[Tutorial] Performing docking using DockingPie plugin in PyMOL.
How to install the DockingPie plugin on PyMOL?
DockingPie  is a plugin of PyMOL  made to fulfill the purpose of docking within the PyMOL interface. This plugin will allow you to dock using four different algorithms, namely, Vina, RxDock, SMINA, and ADFR. It will also allow you to perform flexible docking. Though the installation procedure is the same for all OSs, in this article, we are installing this plugin on Ubuntu (Linux).

DS Visualizer: Uses & Applications
Protein structure & folding information exploited from remote homologs.
Remote homologs are similar protein structures that share similar functions, but there is no easily detectable sequence similarity in them. A new study has revealed that the protein folding information can be exploited from remote homologous structures. A new tool is developed to recognize such proteins and predict their structure and folding pathway. (more…)
Pathonoia- A new tool to detect pathogens in RNA-seq data.
Detecting viruses and bacteria in RNA-seq data with less false positive rate is a difficult task. A new tool is introduced to detect pathogens in RNA-seq data with high precision and recall known as Pathonoia .
AlphaFill- New algorithm to fill ligands in AlphaFold models.
AlphaFold is a popular artificial intelligence based protein prediction tool . Though it predicts good protein structures, it lacks the capability to predict the small molecules present in the structure such as ligands. For this purpose, AlphaFill is introduced by Hekkelman et al.,. (more…)
