Anonymize Siemens rda-files

Remove or modify metadata from native Siemens MRS files

This function creates anonymized copies of Siemens rda-files. The function will replace patient identifying information with generic or user specified values. It can also be used to modify non-identifying metadata, such as PatientSex or InstitutionName.

Examples:
Using default values:
anonrda('abc.20071120.123108.rda')

The same, but with progress feedback:
anonrda('D:\Data\MRS\abc.20071120.123108.rda',[],[],true)

The same, but forcing specific parameters:
R.PatientName = 'removed';
R.PatientID = 'PP1234';
[status message] = anonrda('C:\Temp\abc.20071120.123108.rda','PP1234.rda',R,true)
