PROBLEM(s): (i) Attune 1.2.1 does not work on MATLAB on windows 64 bit machines. Error message : " ...undefined file or function attune_lic " (ii) reference to non-existent field 'table' SOLUTION: Missing and updated files need to be copied into attune folder. TO INSTALL: Copy the attune_lic.mexw64 file into the folder where attune was installed. Usually in the matlab root toolbox/attune_v121/ folder. There should be other files similar to attune_lic.mex* in the same folder. Replace all the other files (*.m, *.p, *.jar) into the Attune Folder.
