# Script Block Examples – Blue Read

var blueReadMarkings = $Tasks.Task.DeepLearningRuntimeBlock.Sample.Markings["Read"] as IBlueMarking;

var readmodelmatch = blueReadMarkings.Views.First().Matches.First() as IReadModelMatch;

var resultString= readmodelmatch.FeatureString;

return resultString;

- Convert Runtime Block's Sample object to an IBlueMarking object.
var blueReadMarkings = $Tasks.Task.DeepLearningRuntimeBlock.Sample.Markings["Read"] as IBlueMarking;
- Convert Blue Tool's model matches to IReadModelMatch.
  This line of code presumes that there is only one view, and only one model type.
  var readmodelmatch = blueReadMarkings.Views.First().Matches.First() as IReadModelMatch;
- Get the Model Match Feature String.
var resultString= readmodelmatch.FeatureString;
- Return the resultString to the Task level.
return resultString;
