 Presentations at ISMB 1994 were split further into three themed days, focusing on protein secondary structure prediction, sequence analysis and AI techniques and biochemical applications, respectively.As attendance at ISMB increased, the single track approach became increasingly unsustainable and two parallel tracks were introduced at ISMB/ECCB 2004.Further expansion meant that, by ISMB 2012, over 200 talks were presented in nine parallel tracks including multiple proceedings tracks, a highlights track and a technology track.
