DirectRT will look for a style file in the directory that the experiment is it, otherwise it will default to the styles file in the main DirectRT directory. If you change the one in the main directory, and not create copies to the individual experiment directories, it will change the styles for all experiments without a specific styles file. I suggest arranging each experiment into an individual folder, and copy the main styles file into each experiment folder. I would then rename the styles file to specify which experiment it belongs to and adapt it to what the experiment needs. Hope this helps.
