Neural query system: data-mining from within the NEURON simulator

We have developed a simulation tool within the NEURON simulator to assist in organiza-tion, verification, and analysis of simulations. This tool, denominated Neural Query System (NQS), provides a relational database system, a query function based on the SELECT function of Structured Query Language, and data-mining tools. We show how NQS can be used to organize, manage, verify, and visualize para-meters for both single cell and network simula-tions. We demonstrate an additional use of NQS to organize simulation output and relate out-puts to parameters in a network model. The NQS software package is available a
