I'm having trouble loading any .nirs files into Brain AnalyzIR/NIRS Toolbox. When I try to use nirs.io.loadDotNirs, the following error appears:

Warning: Invalid default value for property 'auxillary' in class 'nirs.core.Data':
Undefined function or variable 'Dictionary'.
> In nirs.io.loadDotNirs (line 134)

Any help would be greatly appreciated!
