How can I change a plot based on the file name?

I want to plot some knee angles but I want to change the line style based on the file names.
An example of the file names would be:
BFND_W1. c3d
BFND_W1.plus3.c3d
BFND_W1.minus3.c3d
So for all fname's containing "plus", I want it to plot a "--" line and for all fname's containing "minus", I want to plot a ".." line.
I tried to use an if elseif code but just don't know how to code "if fname contains the word plus", "elseif fname contains minus".
Thanks in advance!!

Alexis - depending upon your version of MATLAB, you can use use either strfind or contains to determine if a substring exists within your filename. For example, the code
filename = 'BFND_W1.minus3.c3d';
linestyle = '-';
if ~isempty(strfind(filename, 'plus'))
linestyle = '--';
elseif ~isempty(strfind(filename, 'minus'))
linestyle = '-.';
end
% plot your data with the chosen LineStyle
plot(1:10,1:10,'LineStyle',linestyle);
might do what you want.
