HalX:: an open-source LIMS (Laboratory Information Management System) for small- to large-scale laboratories

Structural genomics aims at the establishment of a universal protein- fold dictionary through systematic structure determination either by NMR or X- ray crystallography. In order to catch up with the explosive amount of protein sequence data, the structural biology laboratories are spurred to increase the speed of the structure- determination process. To achieve this goal, high-throughput robotic approaches are increasingly used in all the steps leading from cloning to data collection and even structure interpretation is becoming more and more automatic. The progress made in these areas has begun to have a significant impact on the more ' classical' structural biology laboratories, dramatically increasing the number of individual experiments. This automation creates the need for efficient data management. Here, a new piece of software, HalX, designed as an ' electronic lab book' that aims at ( i) storage and ( ii) easy access and use of all experimental data is presented. This should lead to much improved management and tracking of structural genomics experimental data.
