Getting poster data...
Malcolm Hinsley, Gemma Barton, Ed Griffths ((Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge, CB10 1SA, UK)Displaying high volume data on standard desktop PC hardware presents challenges both in providing an efficient solution that operates at human speeds and also in providing tools that help the annotator understand and manipulate the data. Mapping sequence coordinates to pixel boundaries in real-time allows effectively instant presentation of the underlying data at any level of zoom with no loss of detail. Typically the time required for a display refresh with a dataset of 250k features is under 300ms. RNAseq data can come in very high volumes and we also present some approaches to visualising this such that the annotator can extract the information they want from the mass of data. A naive approach would require in some cases a display over 15000 pixels wide to show these alignments yet some simple techniques can reduce this to a manageable amount with no loss of information.
