Geoseq Analysis. Geoseq uses a tiered process to analyze sequencing data. A. Reads from a deep sequencing experiment are converted into a suffix index for rapid querying. Querying of an input sequence against the experiment is done by breaking the sequence into all possible tiles of a given size and finding the frequency of each tile in the suffix index. B. Visualization of the results can be done in either the Starts View which shows the hits for a tile at the position of the start of the tile, or the Coverage View which integrates hits from all tiles covering a particular position.
