Once you've trained your algorithm on those 60 cases the NCI-ISBI Challenge Committee will provide you access to a new 10 case "Leader board" set to which you will not have .NRRD markup data. "Leader board" is a popular term (borrowed from golf) for a procedure to see how well you are doing on a pre-test set to get a sense of your relative competitive rank before submitting to a final test. The results of your participation in the Leader board will be returned to you as feedback on a subset of sequestered markups retained on the judging analytic software using Kitware's MIDAS software. You may then use those results for further tuning your algorithm to prepare yourself for the final "Test" set of 10 totally new cases on which you will run your algorithm while attending the ISBI meeting in April 2013.
