Dear experts,

I´m trying to run NiiStat with lesion masks.
I created the .mat files of the normalized masks and the excel file is ready with the behavioral data.
But when I try to run NiiStat with the GUI i get a matlab error:

Warning: Escaped character '\P' is not valid. See 'doc sprintf' for supported special characters.
Error using NiiStatGUI/GOButtonPushed (line 444)
Unable to write file C:

Error in appdesigner.internal.service.AppManagementService/tryCallback (line 207)
callback(app, event);
Error in matlab.apps.AppBase>@(source,event)tryCallback(appdesigner.internal.service.AppManagementService.instance(),app,callback,requiresEventData,event)
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 262)
Error while evaluating Button PrivateButtonPushedFcn

I´m using Windows 7 as an operative system, Matlab R2016b, and SPM12.

any help would help me a lot,

Diana
