Which OS are you in?
If the alps is installed on linux, check the file permission.
If it is installed on Windows, check the property of the file and uncheck the read-only box.

Dear Sir/Madam:

I am using ALPS now, but I have a question, can I add a new lattice to lattice.xml ? I did it, however, I was denied the right to do some change? What should I do ?

best wishes !
