-An optional second input argument is the path to an existing morphology file for importing a previously created morphology into the program for further modifications.

 Users can also import morphology sets previously generated by the Ising_OPV tool for further modification and analysis.
 To import an entire set of 10 morphologies in a parallel processing environment:
 
->    mpiexec -n 10 Ising_OPV.exe parameters_default.txt -import morphology_#.txt
+>    mpiexec -n 10 Ising_OPV.exe parameters_import.txt -import morphology_#.txt
 
 This command will import 10 morphologies (morphology_0.txt, morphology_1.txt, etc) and assign one to each processor.
-These morphology files must be located in the working directory to be found and imported into the simulation.

+Finally, users can import experimental tomogram data, generate a morphology set from the data, and then perform further operations:

-Finally, users can import experimental tomogram data, generate a morphology set from the data, and then perform further operations.
+This command will load the metadata about the tomogram image data from the .xml file and then use that for interpreting the .raw data file.  Once the tomogram data is loaded, the morphology will be segmented into 10 equal sub-volumes to form the morphology set and then the normal analysis is performed. Again, these tomogram morphology files must be located in the working directory to be found and imported. Also, the metadata format required by Ising_OPV is defined in XML schema file, tomogram_metadata.xsd.
 
 #### Output
 Ising_OPV will create several output files:
