Hi experts, 

To give more detail re my previous post....  I have created the .Qdecrc file in my Subjects directory and QDEC folder, which contains one line : MEASURE1 = pial_lgi . However, LGI is still not appearing in the drop down menu on QDEC. 

When I do command more ~/.Qdecrc it gives the following output:

# This file is automatically generated by the application

# If you change any lines or add new lines, note that all

# coments and empty lines will be deleted. Every line has

# to be in format: 

# key = value

#
