 Academic papers at ISMB were traditionally presented in a single track . 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 . The introduction of parallel tracks to ISMB was controversial . Christopher Rawlings ( head of Computational and Systems Biology at Rothamsted Research and organiser of ISMB 1995 ) has said : " There were a lot of people who wanted to keep it more strongly in the AI intelligent systems model and have a meeting where everybody would go to everything . But it just grew too big . We just couldn ’ t . " As the number of submitted proceedings papers has increased , the acceptance rate has decreased dramatically , from 75 % in 1994 to 13 % in 2012 . ISMB proceedings from 1993 @-@ 2000 were published by AAAI Press . Since ISMB 2001 , proceedings have been published in the journal Bioinformatics . The number of posters presented at ISMB has also increased dramatically . 25 posters were presented at ISMB 1994 ; at recent ISMB meetings , 500 @-@ 1 @,@ 000 posters have been presented in multiple poster sessions .
