One way to visualize the similarity between two protein or nucleic acid sequences is to use a similarity matrix, known as a dot plot. These were introduced by Gibbs and McIntyre in 1970 [1] and are two-dimensional matrices that have the sequences of the proteins being compared along the vertical and horizontal axes.
This list of protein subcellular localisation prediction tools includes software, databases, and web services that are used for protein subcellular localization prediction. Some tools are included that are commonly used to infer location through predicted structural properties, such as signal peptide or transmembrane helices , and these tools ...
The dot-matrix approach, which implicitly produces a family of alignments for individual sequence regions, is qualitative and conceptually simple, though time-consuming to analyze on a large scale. In the absence of noise, it can be easy to visually identify certain sequence features—such as insertions, deletions, repeats, or inverted repeats ...
YASS (Yet Another Similarity Searcher) [1] [2] is a free software, [3] pairwise sequence alignment software for nucleotide sequences, that is, it can search for similarities between DNA or RNA sequences.
It uses the PAM120 scoring matrix for the calculation of complexity. yes [16] AlcoR 2022 downloadable: A compression-based and alignment-free tool for detecting low-complexity regions in biological data (see: Kolmogorov complexity § Compression) yes [17]

Sequence searches are a standard tool in modern biology with which the function of unknown proteins can be inferred from the functions of proteins with similar sequences. HHsearch and HHblits are two main programs in the package and the entry point to its search function, the latter being a faster iteration.
UTOPIA (User-friendly Tools for Operating Informatics Applications) is a suite of free tools for visualising and analysing bioinformatics data. Based on an ontology-driven data model, it contains applications for viewing and aligning protein sequences, rendering complex molecular structures in 3D, and for finding and using resources such as web services and data objects.
