Advances in high-resolution mass spectrometry facilitate the identification of hundreds of metabolites, thousands of proteins and their post-translational modifications. This remarkable progress poses a challenge to data analysis and visualization, requiring methods to reduce dimensionality and represent the data in a compact way. To provide a more holistic view, we recently introduced circular proteome maps (CPMs). However, the CPM construction requires prior data transformation and extensive knowledge of the Perl-based tool, Circos. ...

...Please refer to: https://github.com/suhrig/pingpongpro Piwi-interacting RNAs (piRNAs) are a class of small non-coding RNAs, predominantly active in the germ line. There, they limit the detrimental effect of transposons on the genome. They do so by forming a complex with Piwi proteins. The complex binds and then cleaves mRNA molecules of active transposons. The resulting mRNA fragments induce the production of more piRNAs, thus reinforcing the anti-transposon response in a feed-forward loop called the "ping-pong cycle". A key question in ping-pong cycle research is identification of piRNAs which are amplified through the cycle. ...

...Protein Contact Map Generator (PCMGen) is a command line tool which takes protein 3D structures (PDB format files) as input and computes contact distances between two chains (from single or two different proteins). These matrix files can be further visualised as Contact Maps using other visualization tools/ programs (like R-heatmaps). Contact Maps can be used to understand proteins' : 1. Secondary structures 2. Conformational arrangements 3. Surface interactions
