Hi,

i use the vehicle Network Toolbox to read MDF files. With a new dataset i got an error that a variable name is not valid (see pic). I recognized that the Name is too long. How can i work around this? Is there any possibility to increase namelengthmax? </matlabcentral/answers/uploaded_files/127170/namelengthmax.png>

MDFobj=mdf(inFilename.full);
grpChannelNames=MDFobj.ChannelNames;
...
            if any(Selection)
                Data{n,1} = read(MDFobj,n,grpChannelNames{n}(Selection)); % error here
                ChannelNames{n} = ChannelNames{n}(Selection);
                ChannelGroup(n).Channel = ChannelGroup(n).Channel(Selection);
            end
