<body class='hmmessage'><div dir='ltr'>Hi everyone,<br><br>I am new to FieldTrip and am confused about the <font style="" face="Courier New,sans-serif">cfg</font> structure that is required for running Field Trip functions. I would like to plot the topographical maps of a frequency range (e.g. 5 to 10 Hz) using Field Trip. I used the <font style="" face="Courier New,sans-serif">besa2fieldtrip</font> function to create data.<br><br>I receive the following error message when running <font style="" face="Courier New,sans-serif">ft_topoplotER</font>. Please let me know why the following error appears.
