+% This script has been implemented due to incompatibility between MSA
+% variables names and PRP ones. This is due the fact that refactoring has
+% been carried out in MSA and not in PRP (hope in the future PRP would have
+% the same var names!)
+% For now, this script which renames the fields in aeroCoefficients.mat and
+% also extract one motor among the stored ones because PRP is able to
+% handle one motor per time. They don't have appended structs in their
+% coeffs.mat
+%
+% How to use:
+% 1. Change mission name to let the script find the correct folder and path
+% 2. Choose from the dialog window the motor which PRP has asked
+% 3. coeffs.mat will appear in your misson folder, at the level of data and
+%    config folder (not inside of them!)
+%
+% Typical output:
+%
+% coeffs.mat does not exist. Creating a new file...
+% Loaded motor: HRE_ARM_OPT_2_Venturi
+% PATH: D:\GitHub\msa-toolkit\common\missions\2025_Orion_Portugal_October\data\aeroCoefficients.mat
+% Motor data saved to coeffs.mat
+% PATH: D:\GitHub\msa-toolkit\common\missions\2025_Orion_Portugal_October\coeffs.mat
