Voxler does not recognize blank cells in input data as a no data value, it skips the cell. If the first cell of a data column is blank or empty, Voxler does not recognize that the column is a column that contains data. This causes the column to not appear in the drop-down menus in the Property Manager. It is recommended that a data value of 0.00 is used for blank cells if this issue occurs for you.
