NOTE: 1 to i refer to the simualtion number. for cases InitialSimsTI000_5, InitialSimsTI001_0 and InitialSimsTI002_0 there are 50 cases, i.e. i = 50. For the InitialSimsTI010_0 case there are 10 cases, i.e i = 10.

CMMetricsTIxxx_x:

Here XXX_X is the TI for the simulation contained in the matlab workspace e.g. CMMetricsTI010_0.mat contains the condition monitoring metrics outlined in [1] for the TI = 10% simulations.

NormCMData: Matrix (4 by (number of simulations x number of fault cases))
The matrix contains the normalised condition monitoring metrics detailed in [1], each row contains a specific metrix i.e row 1 contains CM metric 1 (as defined in [1]). In the case of the TI000_5 to TI002_0 cases, there are 50 simulations of 4 differing rotor conditions, resulting in 200 columns.
The first 50 contain data relatig to the optimum case and so on, in the order 'Optimum', 'Off6_5', 'Off9', 'Off12'.
This data was used to train the NBCs detailed in [1].
