Open Source Perl Data Management Systems

MRTG is a free, open-source tool designed to monitor and measure the traffic load on network links. It generates HTML pages containing graphical representations (PNG images) of network traffic, providing visual insights into bandwidth usage over time. Originally developed to monitor router traffic, MRTG has evolved to graph various network devices and other metrics.

xoscope is a digital oscilloscope using input from a sound card or EsounD and/or a ProbeScope/osziFOX and will soon support Bitscope hardware. Includes 8 signal displays, variable time scale, math, memory, measurements, and file save/load.

Flame graphs are a visualization of profiled software, allowing the most frequent code-paths to be identified quickly and accurately. They can be generated using my open source programs, which create interactive SVGs. See the Updates section for other implementations. Recently I've been helping with d3-flame-graph. The x-axis shows the stack profile population, sorted alphabetically (it is not the passage of time), and the y-axis shows stack depth, counting from zero at the bottom. Each rectangle represents a stack frame. The wider a frame is is, the more often it was present in the stacks. The top edge shows what is on-CPU, and beneath it is its ancestry. The colors are usually not significant, picked randomly to differentiate frames. Flame charts were first added by Google Chrome's WebKit Web Inspector (bug). While inspired by flame graphs, flame charts put the passage of time on the x-axis instead of the alphabet.

The ggplot2-book repository contains the source for ggplot2: Elegant Graphics for Data Analysis, written by Hadley Wickham. The book explains the theory and application of the ggplot2 package in R for data visualization, guiding readers through its layered grammar of graphics approach. It serves as both a practical guide and conceptual reference for building advanced plots and mastering ggplot2.

FlowViewer provides a convenient web-based user interface to Mark Fullmer’s flow-tools suite and CMU's netflow data capture/analyzer, SiLK. The inclusion of the underlying SiLK tool set enables FlowViewer users to continue to use the tool with the newer IPFIX netflow data protocol, which includes support for IPv6 and Cisco's v9 and FNF netflow. FlowViewer has been developed for NASA’s Earth Sciences Data and Information System (ESDIS) networks, and credit goes to NASA for their usual outstanding support of innovation. The FlowViewer tools provide additional graphing and tracking features by utilizing open source software including Thomas Boutrell’s gd, Lincoln Stein's GD, Martien Verbruggen's GD::Graph, and Tobias Oetiker’s RRDtool. FlowViewer v4.6 fixes non-UTC local time environments for FlowViewer and FlowGrapher, and $no_devices_or_exporters FlowMonitor_Collector problem. **Note: SiLK must be v3.8.0 or later. Version 3.9 handles sFlow data.

Data mines the voting record and other actions of Members of the UK Parliament. Extracts information from the parliament website and stores it in a database. Provides tools to analyse the information, producing statistics and tables about the MPs.

Gplot provides a convenient front-end for gnuplot. It accepts a large set of options to generate a single plot of one or more sets of data (overlaid as necessary).

As of 2018-06-28, this project has moved to https://github.com/AdamaJava. This copy of the code will remain but all new code updates and releases will be from the new site. Java code developed by the Australian ICGC team for operating on next-generation sequencing data. This code is currently being maintained and expanded by the QIMR Berghofer Genome Informatics team (http://www.qimrberghofer.edu.au/lab/genome-informatics/) More details and documentation can be found on the wiki: http://sourceforge.net/p/adamajava/wiki/Home/

CViT - Chromosome Viewing Tool. A collection of Perl scripts that enable quick visualizations of features on linkage groups, psuedochromosomes or cytogenetic maps. Intended for whole-genome views of data but can be used to create images of single chromosomes/linkage groups, contigs, or BACs, or even proteins -- any feature that has a location on a backbone. Handles most standard genetic/genomic coordinate systems. Reads GFF3 data and produces a PNG or SVG image.

Cap analysis of gene expression (CAGE) is a sequencing based technology to capture the 5’ ends of RNAs in a biological sample. After mapping, a CAGE peak on the genome indicates the position of an active transcriptional start site (TSS) and the number of reads correspond to its expression level. CAGE is prominently used in both the FANTOM and ENCODE project. MOIRAI is a compact yet flexible workflow system designed to carry out the main steps in data processing and analysis of CAGE data. MOIRAI has a graphical interface allowing wet-lab researchers to create, modify and run analysis workflows. Embedded within the workflows are graphical quality control indicators allowing users assess data quality and to quickly spot potential problems. MOIRAI package comes with three main workflows allowing users to map, annotate and perform an expression analysis over multiple samples.

g2 is an easy to use, portable and powerful 2D graphics library. It provides a comprehensive set of functions for simultaneous generation of graphical output on different types of devices.

miARma-Seq, which stands for miRNA-Seq And RNA-Seq Multiprocess Analysis, is a suite designed to study mRNAs, miRNAs and circRNAs. It is able to perform differential expression analysis, miRNA-mRNA target prediction and functional analysis among others. Most importantly, it can be applied to any sequenced organism, and it can be initiated at any step of the workflow. As a stand-alone tool, is both easy to install and extremely flexible in terms of its use. It brings together well-established software in a single bundle, allowing a complete analysis from raw data. All the capabilities can be easily and simultaneously enabled at will, regardless the step in the workflow.

PHP tool to display graphs and stats based on temperature readings stored in MySQL from 1-wire or any source of data. Also supports alarms, mobile access, and logging data from digitemp. Works in any browser.

Evoker is a graphical tool for plotting genotype intensity data in order to assess quality of genotype calls. It implements a compact, binary format which allows rapid access to data, even with hundreds of thousands of observations. PLEASE NOTE: This source repository is no longer active. See the github link above for the latest version.

A graphical microcode simulator with a reconfigurable datapath.

This project aims at displaying and analysing data recorded by Arexx temperature loggers on Unix operating systems. Although the code is currently implemented for etching data from Arexx loggers, the UI itself is completely independent and can be reused with other temperature databases.

The goal of the Perl OBD-II Logger project is to create a flexible and efficient application that can capture and log OBD-II Mode 0x01 PID data from an automotive scantool. It is designed with accurate and efficient PID data logging in mind, and provides NO support for reading or resetting diagnostic trouble codes. By default, the output log file contains time-stamped PID values in a simple Comma Separated Values (CSV) format that can be readily imported into popular data analysis or spreadsheet applications. (Output to an SQLite3 database file is also available). It is written in Perl, so it runs in any computing environment with a working Perl interpreter. The program supports scantools that are based on the ELM Electronics ELM327 or OBD Solutions STN1110 programmed microcontrollers. It has been tested with scantools using legacy RS-232 serial, serial over USB, and Bluetooth hardware interfaces. Perl OBD-II Logger even runs on the popular Raspberry Pi computer!

VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data.
