[FieldTrip] reject component

[qi li]

Hi there,

I am having trouble to reject components after ICA/PCA done. Can somebody
help on this?

My command is as follows,
cfg=[];
cfg.topo=comp.topo;
cfg.topolabel=comp.topolabel;
comp_o=ft_componentanalysis(cfg,data_I4);
cfg=[];
cfg.component=[1 3 7];
data_I4c=ft_rejectcomponent(cfg,comp_o)

Errors pop up,

Reference to non-existent field 'invcomp'.

Error in ft_rejectcomponent (line 181)
  [junk, remove]    = match_str(comp.label, tmp.balance.invcomp.labelnew);
