The ""RNA/DNA/FlowThrough registration wizard"" will accept this, but when storing the information a negative original quantity is calculated which is not allowed by BASE. The wizard should be modified so that the original quantity is never less than 0. The workaround so far has been to modify the data file and replace all negative concentration values with 0.",enhancement,closed,minor,Reggie v3.5,net.sf.basedb.reggie,fixed,,
