rdkit, a chemistry toolkit, integrates with IPython to display molecular structures.
The PyGrads Python interface to the OpenGrADS tool for access, manipulation, and visualization of earth science data.
QIIME (canonically pronounced "chime") stands for Quantitative Insights Into Microbial Ecology. QIIME is an open source software package for comparison and analysis of microbial communities, primarily based on high-throughput amplicon sequencing data (such as SSU rRNA) generated on a variety of platforms, but also supporting analysis of other types of data (such as shotgun metagenomic data).
KlustaViewa is a Python GUI software for the manual step of spike sorting, which aims at extracting spiking activity from raw extracellular multielectrode recordings. An IPython console can be opened in the program to let the user perform his own analyses on the data.
Beaker (source code) is a language-agnostic notebook UI that uses IPython kernels to power several of its backend languages and uses code from IPython's notebook viewer for the backend of its sharing service.
QtIPy is a GUI utility to enable automated running of IPython notebooks in response to file or folder changes and timers. Use it to generate automated reports and analysis for experimental data sets, output together with the code that made them.
The Spyder integrates the IPython Qt console, and IPdb for debugging. It also handles the connection to remote kernels.
scikit-bio is an open-source, BSD-licensed, python package providing data structures, algorithms, and educational resources for bioinformatics.
EMPeror is a WebGL tool for visualizing high-dimensional spaces typically through techniques like principal coordinates analysis.
qiita (canonically pronounced cheetah) the QIIME databasing effort to enable rapid analysis of microbial ecology datasets. The Qiita repository is responsible for defining the data model and the Python API for interacting with a Qiita database. Qiita relies on IPython for parallel compute support.
WooDEM, environment for Discrete Element Modeling and multi-body dynamic,s uses IPython for interactive access to all internals of simulations (exposed from c++ via boost::python).
neuropy is a command-line based Python program for interactive analysis of sorted neuronal spike data, stimulus data, and LFP waveforms. neuropy embeds IPython within its main Qt window.
The Software Carpentry Project, led by Greg Wilson, uses the IPython Notebook as one of its core technologies.
The NIH-funded course on Next-Generation Sequencing, also taught by Titus at MSU, is also based on IPython Notebooks.
Tom Softbaugh's Software development in Python course.
QIIME Workshops are taught using tutorials written to run using IPython Notebooks.
Scrapy, a web-scraping framework, uses IPython for its interactive shell if it's installed.
