Created attachment 393 neuromag freq structure that gives an error when trying to use ft_plot When I try to use ft_singleplotTFR with a freq structure (made a few months back) I get the following error. Before updating it worked fine. See attached freq structure to replicate the error. ft_singleplotTFR(cfg,freq) 199 tmp = sum(abs(grad.tra),2); Reference to non-existent field 'tra'. Error in ft_chantype (line 199) tmp = sum(abs(grad.tra),2); Error in ft_datatype_sens (line 150) sens.chantype = ft_chantype(sens); Error in ft_datatype_freq (line 104) freq.grad = ft_datatype_sens(freq.grad); Error in ft_checkdata (line 204) data = ft_datatype_freq(data); Error in ft_singleplotTFR (line 99) data = ft_checkdata(data, 'datatype', 'freq'); Cheers, Niels

I can reproduce the error with revision 7184 and >> ft_singleplotTFR([], freq) Reference to non-existent field 'tra'. Error in ft_chantype (line 199) tmp = sum(abs(grad.tra),2); Error in ft_datatype_sens (line 150) sens.chantype = ft_chantype(sens); Error in ft_datatype_freq (line 104) freq.grad = ft_datatype_sens(freq.grad); Error in ft_checkdata (line 204) data = ft_datatype_freq(data); Error in ft_singleplotTFR (line 98) data = ft_checkdata(data, 'datatype', 'freq');

(In reply to comment #1) and with >> ft_datatype_sens(freq.grad) Reference to non-existent field 'tra'. Error in ft_chantype (line 199) tmp = sum(abs(grad.tra),2); Error in ft_datatype_sens (line 150) sens.chantype = ft_chantype(sens);

It was due to chantype assuming that grad.tra would exist, but there seem to be cases where it does not exist. mac001> svn commit test/test_bug1894.m fileio/ft_chan*m Sending fileio/ft_chantype.m Sending fileio/ft_chanunit.m Adding test/test_bug1894.m Transmitting file data ...
