First of all, it's difficult to know what you are talking about when you don't even give us the name of the plugin that you are trying to use.
This page contains all the available documentation on the plugin:
http://rsbweb.nih.gov/ij/plugins/fraclac/fraclac.htmlIf you can't find your answer by reading the manual (some of the manual appears outdated or missing), then, if I were you, I would probably send a polite e-mail to the creator.

Dear All,
I have a quastion regarding the values of the column entitled 'mean mass fractal dimension', action LCFD, in the 'FL local connected fractal dimension results' table (12th column). These were (for all images i analyzed) negative numbers between -0.5 and -1.8. How should I interprete them? Can I simply treat them as positive numbers? Is mass fractal dimension the same as mass dimension and regards:
DBmass= limε→0[ln με ⁄ln ε] ?
Thank You for each information!
