Extract properties from Maestro, Sequence and Alignment Cells. Note that the list of available properties can only be determined if the data provided by the upstream node is already available.
The names of data items in a Maestro format file follow a convention which allows the type of the data item and the “owner” of the data to be identified. Names have the form 't_o_d', where 't' is the descriptor type, 'o' is the owner and 'd' is the actual data name.
More information on these property names can be found in the Maestro User Manual in the sub-section A.4. Data Item Names under the section The Maestro File Format.
