function mc_Error(errorString,varargin)

% A utility function to make error handling and logging more compact

% A single call to mc_Error will log the error to the global mcLog,

% bring up an error dialog box with your error message, and actually throw

% an exception with the Matlab error function.

%

% FORMAT mc_Error(errorString,other variable arguments)

%

% errorString This is a string message that will be displayed

% to the user. This can either be a simple string,

% or it can take the format of an sprintf

% formatting string using % format specifiers (see

% sprintf documentation for more information about

% these format strings).

%

% other variables If you are using the sprintf format string, you

% need to pass in the other variables that need to

% appear in the formatted string.

%

% EXAMPLES

% mc_Error('File does not exist.');

% mc_Error('File %s does not exist.',filename);

% mc_Error('File %s does not exist at path %s.',filename, folder);

% mc_Error('You specified %d images but I found %d.\nPlease double

% check subject %s folder %s for images.',NumScan(iRun),

% size(P,1),subjDir,RunDir{iRun});

if (~isempty(varargin))

formatcount = size(strfind(errorString,'%'),2);

if (formatcount == size(varargin,2))

errormsg = sprintf(errorString,varargin{:});

else

mc_Error('Found %d format specifiers but %d other variables were provided.\n\nError String: %s\n',formatcount,size(varargin,2),errorString);

end

errormsg = errorString;

end
